Frequently Asked Questions
What are the advantages of this COB LED strip light over traditional SMD strips?
COB LED strips offer a continuous, uniform light line without visible dots, improved thermal management, and higher light density for a premium aesthetic.
Is this 12V COB LED strip light dimmable and what power supply is recommended?
Yes, this 12V COB LED strip is fully dimmable. A compatible 12V constant voltage power supply (driver) is required for optimal performance and dimming control.
What color temperatures and mono colors are available for the 528-4.5 model?
The 528-4.5 model is available in mono white (various CCTs), as well as dedicated Red, Green, and Blue options to suit diverse project requirements.
Can this COB LED strip light be customized for specific project lengths or IP ratings?
While the standard maximum run is 5m with an IP20 rating, DENO LED offers customization for specific project lengths. Higher IP ratings may be available for certain models upon request.
Which aluminum channel should I use with this COB LED strip?
Match the channel inner width to the strip PCB width — 8mm and 10mm COB strips fit DENO 10x10mm, 12x8mm and 17.5x7mm profiles. A surface mount channel suits shelves and ceilings, a recessed trimless channel suits plaster-in cove lines, and the aluminum body also acts as the heat sink the strip needs.

Need more than 12W/m of dot-free light? Meet the SOB upgrade
COB LED strip is the reference for seamless, dot-free lines — bare flip-chip dies sit under one shared phosphor layer, and conventional COB strip is generally limited to about 12W/m. DENO's SOB (Solder-on-Board) series builds the same continuous line from individually encapsulated SMD packages, with verified builds up to 24W/m at 24V DC (25 °C ambient, aluminum profile). Spec COB for shorter, lower-load coves and joinery; consider SOB when the output target, cut unit or package protection calls for it — run length always depends on the exact model and feed layout.
