Frequently Asked Questions
What are the common applications for the COB-512-8mm strip light?
This COB LED strip is ideal for accent lighting, under-cabinet lighting, display cases, architectural coves, and any area requiring a seamless, dot-free linear light source in commercial settings.
What color temperatures and single-color options are available for this series?
The COB-512-8mm series is available in mono white (various CCTs), and also in vibrant single-color options including Red, Green, and Blue to suit diverse project requirements.
Is this COB LED strip dimmable, and what kind of power supply does it require?
Yes, the COB-512-8mm is fully dimmable. It requires a 24V constant voltage (CV) LED driver, which must be purchased separately and matched to the total wattage.
Can DENO LED provide custom lengths or tailored solutions for large projects?
DENO LED offers flexible solutions for B2B clients, including custom length requirements and project-specific consultation. Contact our sales team for detailed customization options and bulk orders.
Is a COB LED strip better than an SMD strip for dot-free lighting?
Yes for continuous linear light. A COB LED strip spreads phosphor over the whole surface, so there are no visible dots even without a deep diffuser, while a standard SMD strip needs 240 LEDs/m plus a frosted cover to get close. Choose SMD only when you need higher output per watt or RGB pixel control.
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.
8mm COB LED Strip — Buyer Questions
When should you use an 8mm COB LED strip instead of 10mm?
Use the 8 mm board when the profile is narrow or the strip must hide inside joinery, and the load stays under about 10W/m. It carries 480 to 576 LEDs/m with the same dot-free 180° line as the 10 mm build, but with less copper it is more sensitive to long runs and high drive currents.

Is an 8mm dot-free LED strip bright enough for cove lighting?
Yes for most coves. At 8–10W/m an 8 mm COB tape puts out roughly 1200–1600 lm/m at 4000K, which lifts a 2.7–3 m ceiling comfortably. For double-height atriums or wall-wash throws over 4 m, step up to a 10 mm board or the SOB high-power line.

Can an 8mm COB LED strip be mounted in a shallow profile?
Yes, and that is its main advantage. Because the emitting surface is already continuous, an 8 mm COB tape needs no diffuser gap — 6–8 mm of depth behind a frosted lens is enough for an even line, where an SMD tape would need 15–20 mm to hide dots.

What voltage options exist on the 8mm COB board?
12V for short furniture and cabinet runs, 24V as the project standard, and 48V where a single feed has to cover 10 m or more. The 8 mm 24V builds are the volume sellers; 5V USB versions are available on request for display and consumer products.

Do you supply 8mm COB LED strip in 5m, 15m and 30m reels?
Yes. Standard 24V reels ship at 5 m, and roll-to-roll unibody production allows continuous 15 m and 30 m reels without a solder joint along the run. Long reels remove the dark gaps that reel-to-reel joints create in a continuous cove line.

Single Colour COB LED Strip — Buyer Questions
Which colour temperature should a single colour COB LED strip be?
Pick 2700K–3000K for hospitality and residential warmth, 4000K for offices and kitchens, and 6000K–6500K for retail, task and technical areas. DENO bins every single colour COB LED strip to SDCM ≤3 so two reels installed end to end read as one colour, and 1800K to 2400K amber options are available for façade and bar work.

How do you cut and connect a COB LED strip?
Cut only on the marked copper pads, then solder or use a clamp connector rated for the board width. Cut units on DENO COB tape run from 22.7 mm on the 4.5 mm 12V board to 50 mm on the 24V 360 LEDs/m board, so check the cutting unit before designing joinery — the shortest usable piece equals one cut unit.

Which COB LED strip works best for under cabinet and shelf lighting?
A narrow 4.5 mm or 8 mm 12V/24V COB tape at 480–528 LEDs/m is the usual answer. It fits shallow aluminium channel under a cabinet or inside a shelf edge, the dot-free line hides no hardware, and the 180° beam fills the worktop evenly without the striping an SMD tape shows at close range.

Need more than 12W/m of dot-free light? Meet the SOB upgrade
COB LED strip is the reference for seamless, dot-free lines — but the shared phosphor layer caps most builds around 12W/m and a 5 m single feed. DENO's SOB series is the direct upgrade: the same continuous line on flip-chip dies and 105 µm copper, carrying 24W/m, CRI 95 and 15 m runs from one feed. Spec the COB range for coves and joinery; step up to SOB when the lux target or the run length says so.
