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.
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.
4.5mm Slim COB LED Strip — Buyer Questions
How narrow can a COB LED strip be?
DENO's slimmest single colour COB board is 4.5 mm wide with 528 LEDs/m at 12V and a 22.72 mm cutting unit. At that width it slides into 6 mm inner-width channels, hides in a shelf lip or a mirror frame, and still produces a fully dot-free line.

Is a 12V COB LED strip better than 24V for furniture lighting?
For runs under 3 m, yes — 12V keeps the driver small and works with existing furniture wiring and battery systems. Past 3 m the voltage drop on a 4.5 mm board becomes visible, so 24V is the safer choice for continuous cabinetry or a full mirror surround.

What is the shortest cut unit on a slim COB LED strip?
22.72 mm on the 4.5 mm 12V 528 LEDs/m board. That is short enough to trim a strip to a cabinet or a stair nosing without a visible dead end. Where a project needs cuts under 5 mm, the SOB micro-cut boards go down to 3.333 mm.

Where is a 4.5mm dot-free LED strip normally installed?
In mirrors and vanities, display cases, shelf edges, handrails and signage returns — anywhere the channel is too small for a standard board and the light source may be glimpsed. The narrow phosphor line reads as a drawn stroke of light rather than a row of LEDs.

- Guide custom widths and lengths
How much power does a slim COB LED strip draw?
Typically 5–8W/m. The 4.5 mm copper cannot dissipate much more, so DENO caps the slim line there and recommends aluminium channel above 6W/m. Higher output in a narrow footprint means moving to an 8 mm board or an SOB build.

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.
