Question 1

What are the advantages of using COB LED strips like the 576-CCT-5 for B2B applications?

Accepted Answer

COB LED strips provide a uniform, dot-free illumination, making them ideal for high-end applications where a seamless light line is required. Their flexibility and narrow profile simplify installation.

Question 2

Is the 576-CCT-5 COB LED strip dimmable and what drivers are compatible?

Accepted Answer

Yes, the 576-CCT-5 is fully dimmable. It requires a compatible 12V constant voltage LED driver. DENO LED can recommend suitable drivers for optimal performance and flicker-free dimming across various control systems.

Question 3

What is the expected lifespan and warranty for this 5mm COB LED strip?

Accepted Answer

This DENO LED COB strip boasts an impressive lifespan of 50,000 hours, ensuring long-term reliability for commercial installations. It is backed by a comprehensive 5-year warranty for peace of mind.

Question 4

Can the 576-CCT-5 strip be cut to specific lengths for custom projects?

Accepted Answer

Yes, the 576-CCT-5 COB LED strip is cuttable every 20.8mm, offering precise customization for various project requirements. This allows for highly tailored lighting designs.

Question 5

Which aluminum channel should I use with this COB LED strip?

Accepted Answer

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.

Question 6

What is a CCT COB LED strip?

Accepted Answer

A CCT (tunable white) COB LED strip carries two white channels — typically 2700K and 6500K — under one continuous phosphor line, so the colour temperature blends anywhere between them with no dots and no colour banding. DENO builds it at 576 LEDs/m on a 10 mm 24V board and 576 LEDs/m on a 5 mm 12V board.

Question 7

What is the difference between dual white and dim to warm?

Accepted Answer

Dual white lets you set any colour temperature independently of brightness; dim-to-warm follows the dimmer, cooling at full output and warming as it dims. Specify dual white CCT for offices, hotels and circadian schedules, and dim-to-warm where the room should feel like halogen at low level.

Question 8

How do you wire a tunable white COB LED strip?

Accepted Answer

Three conductors: a shared 24V (or 12V) positive and one negative per white channel, driven by a 2-channel CCT controller or a DALI DT8 gateway. Total wattage is the sum of both channels, so size the driver for full output on both, not for one.

Question 9

Does a CCT COB strip stay dot-free at every colour temperature?

Accepted Answer

Yes. Both channels sit under the same phosphor sheet, so a mid-point 4000K mix looks as continuous as either extreme. That is the practical advantage over an SMD CCT tape, where alternating warm and cool packages can show a faint two-tone pattern at close range.

Question 10

Where is tunable white COB tape specified?

Accepted Answer

Hotel rooms, meeting rooms, showrooms and homes with circadian schedules — anywhere one installed line must serve daytime task light and evening ambience. The 5 mm 12V CCT board also fits mirror and vanity work where the light must flatter skin tones at 3000K and read accurately at 5000K.

Question 11

What is the difference between CRI 90, CRI 95 and CRI 98 COB LED strip?

Accepted Answer

The gap is in the deep reds and the efficacy you trade for them. CRI 90 suits general architectural light, CRI 95 with R9 > 50 is the practical standard for retail and hospitality, and CRI 98 is specified where colour judgement matters — galleries, showrooms, cosmetics. Each step up costs roughly 5–10% in lumens per watt, so specify the grade the space actually needs.

Question 12

How do you cut and connect a COB LED strip?

Accepted Answer

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.

Question 13

Which COB LED strip works best for under cabinet and shelf lighting?

Accepted Answer

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.
