Frequently Asked Questions
What is the maximum continuous run length for this COB LED strip?
This 480d COB LED strip offers an ultra-long maximum continuous run of 100 meters without the need for additional power injection or welding.
Is this COB LED strip suitable for dimming applications?
Yes, the 480d COB LED strip is fully dimmable, allowing for flexible light control and ambiance adjustment in commercial settings.
What is the cutting increment for installations requiring custom lengths?
The 480d COB LED strip features a convenient 50mm cutting increment, enabling precise customization for various project requirements.
Does DENO LED offer customization options for large B2B orders?
Yes, for large B2B orders, DENO LED can discuss customization options and provide tailored solutions to meet specific project needs.
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.
