01 What Are Tunable White LED Strip Lights?
Tunable white — also called CCT or dual-white — LED strips combine warm-white and cool-white LEDs on one strip, so you can dial the color temperature anywhere between them.
With a simple controller or remote, you can go from a cozy 2700K glow in the evening to a crisp 5000K working light in the morning — no separate strips needed.
Prefer a single fixed color? See our single-color LED strips.
02 How Do Tunable White LED Strips Work?
A tunable white strip carries two sets of LEDs — one warm and one cool — wired to a common power input. A CCT controller blends the two channels, so you can set any color temperature from warm to cool in seconds.
Most are dimmable too, so a single strip covers everything from bright task lighting to a soft night light. They cut to size like any LED strip and run from a standard 12V/24V supply.
For a clean, built-in finish, most installers mount strips inside Profil aluminium LED to hide and diffuse the light.
03 How Do I Change My Cool White LED to Warm White?
You change the color of a white LED strip by changing its color temperature. Color temperature describes how much blue or red light is in the emitted spectrum — the cooler the temperature, the more blue light; the warmer, the more red.
With a tunable white (CCT) strip you don’t need to modify anything — simply use the controller or remote to dial from cool to warm:
1
Choose a CCT Strip
Pick a tunable white (CCT) strip rather than a fixed single-color reel.
2
Connect the Controller
Wire the controller between the strip and the 12V/24V power supply.
3
Set the Color
Dial warm to cool (2700K–6500K) with the remote, wall switch or app.

Q1What is a tunable white LED strip light?
A tunable white strip lets you adjust the color temperature from warm to cool on the same strip.

Q2What is the difference between tunable white (CCT) and single-color LED strips?
Single-color strips are fixed at one color temperature; tunable white strips can be changed at any time.

- Tunable white: adjustable across warm and cool white
- Tunable white needs a controller; single-color runs direct
- Both are cuttable, dimmable and available in waterproof versions
Q3Can tunable white LED strips be used outdoors?
Yes — choose a waterproof version and they are safe for outdoor use.
- IP65/IP67 options protect against dust and moisture
- Silicone-coated strips suit patios, gardens and signage
- Keep the controller and power supply in a dry location
