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.

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.

Frequently asked questions

What are the primary advantages of using a 4.5mm slim COB LED strip compared to standard LED strips?

The primary advantage of the 4.5mm slim COB LED strip is its compact form factor, allowing for discreet integration into narrow channels or architectural features. SCOB technology provides a uniform, dot-free illumination without the need for diffusers, enhancing aesthetic appeal in close-proximity applications.

What are the typical electrical specifications for DENO LED's 4.5mm slim COB LED strips?

DENO LED's 4.5mm slim COB LED strips typically operate at 24V DC. Power consumption varies by model and LED density, commonly ranging from 5W/m to 15W/m. All models are designed for consistent performance, featuring high CRI (>90) and 1 SDCM binning for color accuracy.

Can these 4.5mm slim COB LED strips be cut to custom lengths, and what is the minimum cut unit?

Yes, DENO LED's 4.5mm slim COB LED strips can be cut to custom lengths. The minimum cut unit is typically 50mm, allowing for precise sizing to fit specific project requirements. Custom OEM lengths beyond standard rolls are also available upon request for B2B orders.

What certifications do DENO LED's 4.5mm slim COB LED strips hold, ensuring compliance and quality?

DENO LED's 4.5mm slim COB LED strips typically hold CE, UL, and RoHS certifications. These certifications confirm compliance with European safety, North American electrical safety, and hazardous substance restrictions, respectively, ensuring product quality and suitability for various markets.
