Architectural illumination, when executed with precision, transforms a space from merely functional to truly captivating. Among the myriad lighting techniques, coving light stands as a testament to this principle, offering a sophisticated approach to interior ambiance. It elevates environments by delivering a soft, diffused glow that enhances architectural features and creates an inviting atmosphere. Understanding its principles and components is the first step toward crafting spaces that resonate with comfort and refined design.
What are Coving Lights
Coving light represents a sophisticated application of indirect illumination. Its fundamental principle involves concealing the light source within a dedicated architectural feature, such as a ledge, recess, or trough, typically positioned high on walls or at the junction where a wall meets the ceiling. This structure, often referred to as a "cove," ensures the light fixture itself remains entirely hidden from direct view.
The mechanism of illumination relies on reflection. Light is projected upwards towards the ceiling and across the upper portion of adjacent walls. These surfaces then act as expansive reflectors, scattering soft, diffuse, and evenly distributed light back into the room. This method effectively eliminates the harsh glare and sharp shadows commonly associated with direct lighting, producing a comfortable and visually appealing ambiance. The resulting effect is one where the space appears to be lit by a gentle, sourceless glow, adding depth and architectural interest without revealing the origin of the light.
Why Coving Light Enhances Interior Spaces
The transformative effect of coving light is rooted in the scientific principles of light reflection and diffusion, fundamentally altering the perception of an interior space. Unlike direct light sources that cast concentrated beams, indirect lighting scatters light rays across broad surfaces. When light strikes the ceiling or wall, it disperses in multiple directions, a process that inherently softens its quality. This diffusion minimizes stark contrasts between light and shadow, reducing visual fatigue and the potential for eye strain often caused by direct glare.
This technique profoundly impacts spatial perception. By washing the ceiling and upper walls with a uniform field of light, coving light blurs the hard architectural lines and boundaries of a room. This creates a powerful illusion of greater height and openness, making it an invaluable tool for interior designers, particularly in spaces with lower ceilings or smaller footprints.
The success of any coving light installation depends not solely on the hardware but on a symbiotic relationship between the light source and the architectural surfaces it illuminates. The quality of reflected light is intrinsically linked to the finish of the reflective surface. For optimal performance, ceilings and any reflective wall surfaces should feature a high-reflectance, non-specular finish, such as a flat or matte white paint.
Glossy or semi-gloss finishes can create undesirable "hotspots" or mirror-like reflections of the light source, while dark colors absorb a significant amount of light, drastically reducing system efficiency. The ceiling functions as an active component of the lighting system, serving as the primary luminaire. Therefore, project planning must extend beyond electrical considerations to include meticulous surface preparation, as any imperfections will be amplified by the grazing angle of the light.
In a professional layered lighting scheme, coving light provides the foundational ambient layer—the base level of general, comfortable illumination. This can then be supplemented with focused task lighting, such as under-cabinet lights in a kitchen or a reading lamp, and accent lighting, like adjustable spotlights highlighting artwork or architectural features, to create a complete, functional, and visually dynamic environment.
Coving Versus Cornice Lighting Explained
While the terms "coving" and "cornice" are frequently used interchangeably in casual conversation, they possess distinct architectural meanings that significantly influence lighting design and aesthetic outcomes. Understanding this distinction provides precision and authority to any project discussion.
Coving typically refers to a molding with a simple, uniform profile. Its cross-section is most often a concave curve, such as a quarter-circle, where the dimension of its projection across the ceiling is often similar to its drop down the wall. Due to its clean lines and inherent simplicity, coving is naturally suited to modern and minimalist interior aesthetics, providing a subtle, unobtrusive channel for light integration.
Cornice, by contrast, is generally more ornate and decorative. It is often larger and may feature a non-uniform profile, with different ceiling and wall dimensions. Cornices frequently incorporate intricate patterns and details linked to specific historical architectural periods, such as the egg-and-dart motifs of Victorian design or the geometric styles of the Georgian era. While a cornice can certainly be adapted to house lighting, its primary function often remains that of a decorative architectural element, with light integration being a secondary consideration that must respect its inherent design.
Coving: Characterized by modern, minimalist aesthetics and a uniform profile, ideal for consistent, diffused light spread.
Cornice: Defined by traditional, decorative focus and varied profiles, potentially requiring more complex light integration to preserve its ornate design.
Main Components of a Coving Light System
A high-performance coving light installation is not a singular product but an integrated system of carefully selected components. Each part plays a critical role in the system's performance, longevity, and aesthetic outcome. Understanding the function and key specifications of each component is essential for achieving a professional result. This reframes the process from simply selecting a light to designing an effect, where the entire system must work in harmony.
LED Strips
The dominant light source for modern coving light is the flexible LED strip. This technology has rendered older systems like T5 fluorescent tubes and cold cathode largely obsolete due to numerous advantages. LEDs offer superior energy efficiency, an exceptionally long operational lifespan, significantly reduced maintenance, and a much smaller physical footprint. Crucially for coving applications, they provide continuous, uniform light without the dark spots or shadows that occurred at the ends of fluorescent tubes. Their flexibility in control, including dimming and color-changing capabilities, is also unparalleled.
To select the correct LED strip, one must decode its key technical specifications:
- Brightness (lumens per meter): This metric quantifies the light output. The required lumen value is entirely dictated by the application's goal. For subtle mood or accent lighting, a lower output is sufficient. For general ambient lighting, a mid-range is appropriate. When coving light is intended as the primary source of illumination, a high output is necessary.
- Color Temperature (CCT): Measured in Kelvin (K), CCT describes the color appearance of white light. Lower Kelvin values produce a warmer, more yellowish light, while higher values produce a cooler, bluer light. For most residential settings, a Warm White (2700K to 3000K) is preferred to create a cozy and inviting atmosphere. In kitchens, offices, or commercial spaces, a Neutral White (4000K) can provide a cleaner, more energizing feel.
- Color Rendering Index (CRI): This is a crucial, yet often overlooked, measure of light quality. CRI is rated on a scale of 0 to 100 and indicates how accurately a light source reveals the true colors of objects and surfaces compared to natural daylight. For any high-quality interior space, a CRI of 90 or higher is essential. Light sources with a low CRI (below 80) can make interiors look dull, washed-out, and unnatural, misrepresenting the colors of furniture, artwork, and even skin tones.
- Voltage (12V vs 24V): LED strips are low-voltage devices. For most architectural applications, including coving, a 24V DC system is superior to a 12V DC system. 24V systems are less susceptible to "voltage drop"—a phenomenon where brightness diminishes over the length of the strip. This allows for longer continuous runs of the LED strip before performance is affected, simplifying wiring in larger rooms.
- Wattage (power consumption): Measured in watts per meter, this value indicates the energy consumption of the strip. It is a critical figure for calculating the total power load of the installation, which is necessary for selecting a power supply of the appropriate capacity.
Application Goal | Recommended Lumens (lm/m) | CCT (K) | CRI | Wattage (W/m) |
|---|---|---|---|---|
Subtle Accent | 300-1150 | 2700-3000 | 90+ | 6-13 |
General Ambient | 1200-1850 | 2700-4000 | 90+ | 13-20 |
Primary Illumination | 1650-3300+ | 3000-4000 | 95+ | 16-33+ |
Aluminum Profiles
Using an aluminum profile is not an optional accessory; it is a non-negotiable component of any professional and long-lasting coving light installation. These profiles, also called channels or extrusions, serve several critical functions that extend beyond simple housing.
- Essential for heat dissipation: The primary function of the aluminum profile is to act as a heat sink. LEDs generate heat during operation, and if this heat is not effectively dissipated, it can lead to a significant reduction in the LED's lifespan, lumen depreciation (dimming over time), and color shifting. Mounting the LED strip inside an aluminum channel provides a thermal pathway for heat to escape, ensuring the LEDs operate within their specified temperature range.
- Provides physical protection for LEDs: The profile shields the delicate LED strip from dust, moisture, and accidental physical impact, which could otherwise damage the diodes and circuitry.
- Ensures straight, rigid light lines: A profile provides a perfectly straight and rigid mounting surface, preventing the strip from sagging or creating a wavy line of light. When paired with a diffuser, it helps to shape and soften the light output for a clean, polished, and professional appearance.
- Types: Profiles are available in various forms to suit different installation requirements: surface mount, recessed, corner (often 45-degree angled to direct light optimally), and plaster-in (trimless, for seamless integration where only the light-emitting diffuser is visible).
Diffusers
One of the most common indicators of an amateur LED installation is "spotting"—the visibility of individual bright dots of light from the LEDs, which creates a distracting effect on the illuminated surface. The solution to this problem is a diffuser.
A diffuser is a translucent cover, typically made of polycarbonate or PMMA, that snaps or slides into the aluminum profile. Its purpose is to scatter the light emitted from the individual LED diodes, blending them into a single, uniform, and continuous line of light. The choice of diffuser involves a critical trade-off between diffusion effectiveness and light transmission efficiency:
- Eliminates visible LED "hotspots": This is the primary function, transforming individual points of light into a smooth glow.
- Types: Clear diffusers offer the highest light transmission but minimal diffusion. Frosted (semi-clear) diffusers strike a balance, offering good diffusion with relatively high light transmission. Opal (milky) diffusers provide the best diffusion, completely eliminating hotspots and creating a perfectly smooth, homogenous line of light.
- Trade-offs between light transmission and diffusion: The superior diffusion of an opal diffuser comes at the cost of light transmission, which can be reduced significantly. To achieve a desired level of brightness when using an opal diffuser, it is necessary to select a more powerful, higher-lumen LED strip to compensate for this light loss. This interconnectedness highlights a key principle: the initial aesthetic choice for a perfectly smooth light has a cascading effect on the technical requirements for the entire system.
Power Supplies (Drivers)
The power supply, also known as an LED driver or transformer, is the heart of the system. It performs the crucial function of converting high-voltage mains electricity into the stable, low-voltage Direct Current (DC) required by the LED strips.
- Converts AC to stable low-voltage DC: This conversion is fundamental, as LED strips operate on low-voltage DC, typically 12V or 24V.
- Strict voltage and wattage matching: Selecting the correct driver is a matter of safety and performance. The output voltage of the driver must exactly match the operating voltage of the LED strip. Connecting a 12V strip to a 24V driver, or vice versa, will immediately and irreparably damage the LEDs, the driver, or both. The driver must also have a sufficient power rating to handle the total load of the connected LED strips.
- Importance of derating for longevity: To ensure safety, prevent overheating, and prolong the driver's life, it is standard industry practice to "derate" the power supply. This means the total wattage of the LED strips should not exceed 80% of the driver's maximum rated capacity.
- Strategic placement for ventilation and access: A common challenge for installers is finding a suitable location for the driver, which can be bulky and requires ventilation. Practical locations include placing it in an adjacent closet, an accessible section of an attic or ceiling void, inside a kitchen cabinet, or within a purpose-built in-wall enclosure for the cleanest and most professional installation.
Control Systems
Given that high-output LED strips can be surprisingly bright, the ability to dim the coving light is not a luxury but an essential feature for creating a versatile and comfortable space.
- Dimming capabilities: Implementing dimming requires a compatible system where the LED strip, the power supply, and the dimmer control are all designed to work together. Common professional dimming protocols include 0-10V and DALI, which offer smooth, flicker-free performance. More common in residential settings is phase dimming, but compatibility must be carefully verified.
- Integration with smart home platforms: Modern installations increasingly incorporate smart and wireless control systems. These can range from simple radio frequency remotes to more advanced Wi-Fi or Zigbee-based controllers. These systems allow for convenient control via a dedicated remote, a smartphone application, or integration with smart home ecosystems for voice control through assistants like Amazon Alexa or Google Assistant.
Planning and Installing Coving Light
A successful coving light installation is defined by meticulous planning and attention to detail. The difference between a high-end, architectural effect and a disappointing DIY result lies in understanding and executing a series of critical steps. The physical installation process is relatively straightforward; the most common and costly mistakes—such as uneven light, visible hotspots, and dimming strips—are almost always failures of planning.
Pre-Installation Blueprint
Before any materials are cut or wires are run, a comprehensive plan is essential. This phase is the most critical for ensuring a successful outcome.
- Detailed room layout and precise measurements: The first step is to create a detailed drawing of the room, marking the exact path of the coving light. Precise measurements of each wall segment are required to determine the total length of LED strip and aluminum profile needed.
- Optimal placement guidelines for light source: The positioning of the cove relative to the ceiling and wall is paramount for achieving a soft, diffuse glow. A widely accepted guideline is to place the light source a minimum of 100mm (approximately 4 inches) down from the ceiling and at least 50mm (approximately 2 inches) out from the back wall. This spacing allows the light beam to spread out before it hits the ceiling, softening the light and preventing a harsh, concentrated line of light or "hotspot" directly above the cove.
- Accurate power calculations and wiring plan: Revisit the power calculation: (Total Length [m] x Watts/meter) x 1.2 = Minimum Driver Wattage. With this figure, a suitable power supply can be selected. The next step is to map out the physical location of the driver(s) and plan the entire wiring route from the mains power source to the driver, and from the driver to the LED strip's starting point(s).
Preventing Voltage Drop
Voltage drop is the most common technical problem in large-scale LED strip installations. It is the gradual decrease in electrical voltage along the length of a conductor. In the context of an LED strip, this manifests as a noticeable dimming of the LEDs that are furthest from the power supply. A long run of strip light might be bright at the beginning but visibly dimmer at the end, ruining the uniform effect.
- Understanding the phenomenon and its effects: Voltage drop causes uneven brightness, leading to an unprofessional and visually inconsistent appearance.
- The 5-meter rule for continuous runs: As a general guideline, most standard-density 12V LED strips should not be powered in a single, continuous series longer than 5 meters (16.4 feet). For 24V strips, this maximum run length can sometimes be extended, but 5-10 meters is a safe planning range.
- Solutions: For rooms requiring a continuous perimeter of light longer than the maximum single run, several professional wiring techniques must be employed:
- 24V systems: Starting with a 24V system provides greater inherent resistance to voltage drop compared to 12V, making it the preferred choice for architectural lighting.
- Multiple "home runs": This is the most common professional solution. The total length of strip is divided into sections, each no longer than the maximum recommended run length. A separate, parallel pair of wires is then run from the power supply directly to the start of each new section. The strips are not connected to each other in series.
- Looping: For a complete perimeter around a room, a single, sufficiently powerful driver can be used to power the strip from both ends. The strip forms a continuous loop, and power is injected at both the start and the end point, ensuring voltage is distributed evenly from both directions.
- Heavier gauge wiring: The wire connecting the power supply to the LED strip also contributes to voltage drop, especially over long distances. Using a thicker gauge of wire (a lower AWG number) for these connections will minimize voltage loss.
Step-by-Step Installation
With a solid plan in place, the installation can proceed. Before beginning any electrical work, always de-energize the circuit by switching off the corresponding breaker at the main electrical panel.
- Mounting the coving or profile securely: Thoroughly clean all mounting surfaces of dust and debris to ensure a secure fit and proper adhesion. Measure and cut the aluminum profiles to the required lengths, using a miter saw for clean corners. Secure the profile to the wall or within the cove, ideally using manufacturer-supplied mounting clips or by drilling and countersinking screws.
- Installing the LED strip correctly: Clean the interior of the aluminum profile with an alcohol wipe to ensure the adhesive backing on the LED strip will bond effectively. Starting at one end, gradually peel back the protective layer from the strip's adhesive backing while pressing the strip firmly into the channel. Avoid peeling the entire backing at once, as the strong adhesive can be difficult to reposition.
- Wiring and connections: If the strip needs to be shortened, cut it only at the designated cut points, which are typically marked with a scissor icon and exposed copper pads. Cutting anywhere else will break the circuit. Connections between strip sections or to power wires can be made by soldering, which provides the most secure and reliable electrical connection, or by using high-quality, clip-on solderless connectors. Throughout the entire circuit, it is imperative to maintain correct polarity: the positive wire from the power supply must connect to the positive terminal on the strip, and the negative wire must connect to the negative terminal.
- Thorough final testing: Before installing the diffuser and tidying up, perform a final check of all wiring and connections. Once confirmed, restore power to the circuit and test the entire system to ensure all sections illuminate correctly and respond to the controller or dimmer.
Professional Finishing Touches
The details elevate an installation from good to great.
- Measuring down from the ceiling for visual uniformity: Room ceilings are rarely perfectly level. To ensure the gap between the coving and the ceiling is visually uniform all the way around the room, do not use a spirit level for your reference line. Instead, measure a consistent distance down from the ceiling at multiple points and connect these marks to create your installation line. This ensures the coving follows the contour of the ceiling, hiding any imperfections.
- Staggering rigid linear fixtures: If using rigid linear LED fixtures instead of flexible strips, stagger the joints between adjacent fixtures (similar to laying bricks) to prevent a faint shadow line from appearing at each butt joint.
- Caulking and painting for a seamless appearance: After the coving or plaster-in profile is installed, use a flexible painter's caulk to fill any gaps at the joints, corners, and along the edges where it meets the wall and ceiling. This creates a seamless, monolithic appearance. Once the caulk is dry, prime and paint the coving to match the surrounding surfaces.
Common Coving Light Challenges and Solutions
Manufacturers' instructions provide a roadmap for an ideal installation, but the real world is often more complex. Addressing common challenges demonstrates a deep, experience-based understanding of the entire user journey.
Ceiling Imperfections Highlighted
One of the most frequently cited and unexpected issues is that coving light can unflatteringly highlight ceiling imperfections. Users install their new lighting system only to discover that the upward-directed light acts as "grazing light," which casts long shadows from every minor bump, trowel mark, or uneven patch in the plaster. This exaggerates surface texture and can make a seemingly smooth ceiling look rough and flawed.
- Grazing light effect explained: This effect is not a flaw in the lighting but a fundamental property of light itself. Light that strikes a surface at a very shallow angle is a well-known technique used by lighting designers and architects specifically to reveal and accentuate texture. In the case of coving, this is often an unintended consequence.
- Pre-installation testing with a light source: The most crucial piece of advice is to simulate the effect before committing to the installation. This can be done by holding a powerful flashlight or a portable work light tight against the wall and shining it up and across the ceiling. This simple test will immediately reveal the quality of the surface finish and show how it will look when illuminated from a grazing angle.
- Importance of high-standard surface preparation: The best and most effective solution is to ensure the ceiling surface is finished to a high standard, meaning it is perfectly smooth and free of defects.
- Mitigation through placement and diffuser choice: If refinishing the ceiling is not an option, the effect can be mitigated. Increasing the distance of the cove from the ceiling or angling the light further out into the room can soften the shadows. Using an aluminum profile with a high-quality opal diffuser will also help to soften and spread the light more evenly, reducing the harshness of the grazing effect.
Insufficient Brightness for Primary Lighting
A common point of anxiety for those planning an installation is whether coving light can truly provide enough functional illumination to be the sole light source in a room, or if it will be relegated to mere mood lighting.
- Feasibility of coving as sole light source: The consensus among lighting professionals is that it is entirely possible to use coving as the primary ambient light source, but it requires careful specification of high-output LED strips.
- Minimum lumen output requirements: A lighting design engineer recommends a minimum output of approximately 1000 lumens per meter (around 300 lumens per foot) for this purpose. Anything less is likely to feel underpowered for general illumination.
- Limitations of RGBW strips for white light and solutions: A critical insight is the limitation of many all-in-one RGBW (Red, Green, Blue, White) LED strips. While versatile, the total power of the strip is divided among all the color channels. When only the white channel is activated, it may not be bright enough for primary lighting. For projects where bright, functional white light is the priority and color is a secondary feature, the superior solution is to install two separate, parallel strips within the cove: one dedicated, high-output white-only strip for primary illumination, and a second, standard RGB strip for color-changing effects. This ensures both functions are performed without compromise.
Hiding the Power Supply
LED drivers are essential but can be bulky, generate heat, and require ventilation and future accessibility for maintenance. Hiding them effectively is a frequent logistical puzzle for installers.
- Addressing bulk, heat, and accessibility needs: These factors dictate the placement strategy.
- Practical locations: Common solutions include placing the driver in an accessible space above the room, such as an attic or ceiling void, with low-voltage wires chased down the wall. A nearby closet or a high kitchen cabinet can provide an excellent, accessible, and ventilated location. For the cleanest and most professional approach, especially when multiple drivers are needed for a large room, they can be consolidated within a single, recessed in-wall electrical enclosure.
- Considerations for placement within the cove itself: Some very compact drivers might fit within the cove. However, this should only be done in an inconspicuous corner where it is least visible. It is also critical to overlap the LED strips in this area to prevent a dark spot where the driver is located.
DIY Versus Pre-Made Coving
The premise here is whether an installer should construct a custom cove from standard timber and moldings, or purchase a purpose-built LED coving profile.
- Pros and cons of custom construction: Building a cove from scratch offers maximum design flexibility and customization, allowing the installer to create a profile that perfectly matches the room's existing architectural details. This requires significant skill and time.
- Advantages of purpose-built LED coving profiles: Several companies offer lightweight coving made from high-density polystyrene or polyurethane that comes with a pre-formed channel specifically designed to hold an LED strip and sometimes an aluminum profile. These products can significantly simplify and speed up the installation process.
- Factors influencing the choice based on skill and design: The choice depends on the project's goals and the installer's skill level. Pre-made LED coving is often the faster and more straightforward option for beginners, guaranteeing the correct shape and dimensions. The DIY route offers greater creative freedom for those with more experience and specific design requirements.
Troubleshooting Common Issues
- Flickering: This is often caused by an incompatibility between the dimmer switch and the LED driver, an overloaded power supply, or simply a loose wire connection.
- Incorrect colors or shifts: In almost all cases, this points to an issue with the wiring. Either the polarity is reversed on one of the connections, or one of the color channels has a loose or faulty connection.
- Sections of the strip not illuminating: This is typically caused by one of two things: the strip was cut at a point other than the designated copper cut pads, breaking the circuit, or a connection between two sections is faulty.
Integrating Coving Light into Architectural Design
Coving light is far more than a simple perimeter glow; it is a versatile design language that can be applied in numerous creative ways to enhance architecture and define spaces. The most sophisticated and impactful lighting designs are those that are fully integrated into the building's structure, rather than being applied as an afterthought. Moving beyond the basics unlocks the full potential of this elegant lighting technique.
Living Rooms and Media Centers
In living areas, coving light serves as an ideal foundation for a layered lighting scheme.
- Reducing screen glare: It can provide soft, general illumination that reduces glare on television screens, enhancing viewing comfort.
- Defining zones and highlighting features: More advanced applications involve using linear profiles to define specific zones or highlight architectural features. For example, a recessed channel of light can frame a media wall, creating a floating effect and drawing attention to the entertainment center. Similarly, it can wash light up a feature wall behind a fireplace, adding texture and drama.
Kitchens and Bathrooms
In utilitarian spaces like kitchens and bathrooms, coving light excels at layering atmospheric and functional illumination.
- Layering atmospheric and functional illumination: In a kitchen, a perimeter of warm coving light on the ceiling can be paired with bright, direct task lighting from under-cabinet LED profiles, creating a space that is both welcoming and highly functional for food preparation.
- Creating spa-like retreats: In a bathroom, coving light can transform the room into a spa-like retreat. A soft glow around the room's perimeter is perfect for a relaxing bath, while integrating vertical light strips around a vanity mirror provides flattering, shadow-free illumination for grooming tasks.
Bedrooms and Hallways
The primary goal in a bedroom is often to create a tranquil and relaxing environment.
- Achieving tranquil ambiance: A warm, fully dimmable coving light system can provide a soft, hotel-like ambiance that is perfect for unwinding at the end of the day.
- Enhancing perceived space in narrow areas: In hallways, which are often narrow and lack natural light, coving can have a transformative effect. By washing the walls and ceiling with light, it can make the space feel significantly wider, more open, and more inviting.
Advanced Techniques
Beyond the ceiling perimeter, the principles of concealed, indirect light can be applied to many other architectural elements for a truly integrated and high-end result.
- Accentuation of vaulted and coffered ceilings: Coving light is exceptionally effective at accentuating complex ceiling architecture. In rooms with vaulted ceilings, running a light strip along a ledge or beam can emphasize the room's height and volume. In coffered ceilings, placing light within each recess adds depth, dimension, and a sense of luxury.
- Integrated lighting for shelving and niches: Installing a slim aluminum profile behind the front edge or along the back of bookshelves or display niches creates a beautiful effect. The light can be directed upwards or downwards to highlight the objects on the shelves and make the shelving unit appear to float.
- Illuminating staircases and skirting boards: For a dramatic and modern aesthetic that also enhances safety, LED profiles can be integrated along the stringer of a staircase or directly into a specially designed skirting board (baseboard). This provides low-level wayfinding light and creates a stunning visual effect.
- Intentional wall washing for texture: The grazing effect can be used intentionally. By installing a profile at the base of a wall with a rich texture—such as exposed brick, stacked stone, or Venetian plaster—and directing the light upwards, the texture is revealed in a play of light and shadow, turning the wall itself into a work of art.
Frequently Asked Questions
How does coving light differ from traditional indirect lighting?
Coving light is a specific form of indirect lighting where the light source is hidden within a dedicated architectural feature, such as a ledge or recess, directing light upwards onto the ceiling and adjacent walls.
