COB High-Efficiency Series: Perfect Uniformity for Precision Lighting
Achieving a dot-free, high-fidelity lighting effect is no longer a challenge with our Professional COB Series. Unlike standard SMD strips, COB technology places chips directly on the flexible circuit board under a continuous phosphor layer. This results in a 180° ultra-wide beam angle that eliminates harsh shadows and light “beads,” making it the ideal choice for reflective surfaces like marble countertops or glossy cabinetry.
Key Features:
True Dot-Free Output: this COB strip provides a seamless linear glow right out of the box. No more “beady” light reflections on polished marble counter tops or glossy furniture.
Superior Luminous Efficacy: Engineering a balance between brightness and energy saving, this strip delivers 110-120 lumens per watt, ensuring high brightness with lower heat generation and power consumption.
CRI Ra>90 Color Precision: Designed for environments where color matters. High color rendering ensures that interior decor, merchandise, and skin tones appear natural, vivid, and true to life.
Compact 8mm PCB Design: The slim 8mm width allows for installation in the tightest of spaces, fitting perfectly into minimalist aluminum profiles and slim recessed tracks.
Safety & Reliability Certified: Fully compliant with CE and RoHS international standards, ensuring electromagnetic compatibility and the absence of hazardous materials for global market entry.
Extended 3-Year Warranty: We stand behind our high-density COB packaging technology with a 3-year commercial-grade warranty, providing peace of mind for contractors and project managers.

High-Value COB LED Strip Light RFQ:
Q1: Can these COB strips be used in narrow aluminum profiles?
A: Absolutely. COB technology is perfect for shallow or narrow profiles because it doesn’t need a deep diffuser to blend the light. With 320 or 480 chips/m, the light is already blended at the source, giving you a perfect “light bar” look in even the slimmest furniture tracks.
Q2: What is the benefit of the “Green 3M Tape” used on this COB strip?
A: Unlike cheap generic adhesives, the Green 3M Tape is specifically chosen for its superior thermal conductivity and bonding strength. Because COB strips generate a more concentrated heat line than standard SMD strips, the Green 3M adhesive helps transfer that heat to your mounting surface or aluminum profile more efficiently, protecting the chips and securing the strip for its full 3-year lifespan.
Q3: When should I choose the 480D (480 Chips/m) model over the 320D?
A: If you are using very shallow aluminum profiles or translucent covers where the distance between the LEDs and the diffuser is extremely short, the 480D model is highly recommended. Its ultra-high density ensures a perfect “neon effect” even at close range. For general accent lighting where the strip is hidden deeper in a cove or cabinet, the 320D model offers fantastic efficiency at 8W/m while still providing a dot-free visual experience.
