Quick Answer
For architectural cove lighting, choose COB LED strips with CRI 90+, 2700K-3000K color temperature, and 24V for professional installations. COB provides seamless, dot-free illumination ideal for cove applications. Use dimmable drivers (0-10V or DALI) for smooth brightness control, and IP65 for coves in bathrooms or outdoor eaves.
Why COB is Best for Cove Lighting
Cove lighting reflects light off ceilings and walls, making any LED dots or inconsistencies highly visible. COB strips with 384+ LEDs per meter create a completely seamless, uniform line of light with no visible dots. This produces a premium, professional appearance that SMD strips cannot match at close viewing distances.
Color Temperature Selection
For residential cove lighting: 2700K (warm white) creates a cozy, intimate atmosphere. For commercial/hospitality: 3000K offers a warm yet professional feel. For modern/minimalist spaces: 3500K-4000K provides neutral, clean illumination. Avoid 5000K+ for cove lighting as it can appear harsh and clinical.
CRI Requirements
CRI (Color Rendering Index) measures how accurately colors appear under the light. For architectural lighting, CRI 90+ is strongly recommended—it makes wood tones, paint colors, and artwork appear rich and accurate. CRI 95+ is available for museum, gallery, and high-end residential applications where color accuracy is critical.
Dimming and Control
Cove lighting benefits greatly from dimming capability. 0-10V dimming is the professional standard for commercial projects. DALI offers addressable control for complex installations. TRIAC dimming works for simple residential retrofits. Wireless options (Zigbee, WiFi, Bluetooth) are available for smart home integration. Always use dimmers rated for LED loads.

Frequently Asked Questions
Q: How do I calculate the power supply size for led power supply?
A: Multiply the strip's wattage per meter by total length, then add 20% headroom. For example: 5m × 14.4W/m = 72W + 20% = 86.4W, so choose a 100W power supply. Always use a power supply rated for LED applications.
Q: What should I consider before buying led power supply?
A: Key factors include: required brightness (lumens/m), color temperature, voltage (12V/24V/48V), IP rating for environment, LED density, CRI requirement, dimming compatibility, and total run length. Calculate total wattage to size your power supply correctly.
Q: How do I dim led power supply?
A: Multiple dimming options available: 0-10V, PWM, TRIAC, DALI, DMX512, and wireless (WiFi/Zigbee/Bluetooth). Ensure your dimmer is compatible with the strip's voltage and current. COB strips dim especially smoothly due to uniform light output.
Q: Can led power supply be used outdoors?
A: Only IP65 or higher rated strips are suitable for outdoor use. IP65 for covered/splash areas, IP67 for exposed outdoor, IP68 for underwater/submersion. Always use waterproof connectors and properly seal all connections for outdoor installations.
Q: What is the maximum run length for led power supply?
A: This depends on voltage and copper weight. 12V strips typically max 5m, 24V up to 10m, 48V up to 20m. For longer runs, use power injection at both ends or intermediate points to prevent voltage drop and color shift.
Conclusion
For architectural cove lighting, choose COB LED strips with CRI 90+, 2700K-3000K color temperature, and 24V for professional installations. COB provides seamless, dot-free illumination ideal for cove applications. Use dimmable drivers (0-10V or DALI) for smooth brightness control, and IP65 for coves in bathrooms or outdoor eaves.
