CCT Tunable White COB LED Strip 48V 10mm 480LEDs/m IP20 2700K-6500K 20m Run

A tunable white COB LED strip that shifts from warm 2700K to cool 6500K on the same run, so one installation covers evening warmth and daytime task light. Dot-free 48V COB, CRI over 90, cut to any length you need.

How does a tunable white LED strip work?

Two LED channels sit under one phosphor layer — a warm set and a cool set. A CCT controller varies the balance between them and your eye blends the result. The strip is mixing two fixed whites, not changing colour. Hence three wires: a shared positive marked 48V+, and C− and W− for the two channels.

Will an ordinary dimmer work?

No. A dimmer has one output channel, so it varies brightness only and leaves the colour fixed wherever the wiring lands it. You need a 48V constant-voltage driver for power plus a CCT controller to mix the two channels.

Wire it mains → driver → controller → strip, and size the supply on metres × 10W plus 25%%: 10 metres is 100W, so take a 150W supply. If warm and cool come out reversed, swap C− and W− at the controller — nothing is damaged, both are negatives.

Is it equally bright at every colour temperature?

No, and most suppliers do not say so. The 780 lm/m headline is both channels at full, which lands mid-range. At the extremes only one channel works: roughly 350 lm/m at 2700K and 400 lm/m at 6500K.

If a room will sit at 2700K permanently, size the run on the single-channel figure — or buy a fixed 2700K strip and get the full output for less.

How long a run will one feed carry?

20 metres. Double the 24V version, because 48V halves the current for the same wattage.

Past that the far end dims and drifts warm — that is voltage drop, not a faulty strip. Feed both ends, or a second feed in parallel, never in series. The 24V strip is brighter at 930 lm/m — pick 48V for reach, not output.

Where can it be fitted?

Dry interiors only — IP20. Cut every 50mm on the marked pads. For a bathroom or anywhere damp, specify an IP67 strip instead.

3M adhesive holds on clean, cool surfaces; on longer runs use an aluminium profile as a heatsink. Never power it while still coiled.

• Right for: kitchens, bedrooms, home offices, hospitality and showrooms — anywhere one room does more than one job.
• Not right for: bathrooms, outdoors, or any run that needs one fixed colour.
