Setting up white light (widget type "White light")

Updated 9 October 2026Lighty

With the widget type White light you combine two channels into one light: one for warm white, one for cool white. You get a tile you can use to dim and to adjust the colour temperature smoothly from cosy warm to clear and bright. Ideal for tunable white strips, which are often also sold as CCT or dual white.

1. Choose the widget type

Go to Lighting, then to Add widget and choose White light (warm & cool white).

Choose widget type: light, ambient light and white light

2. Choose the module

Choose the Lighty your strip is connected to.

Choose module: Lighty with a descriptive name

3. Set the two channels

Set which channel the warm white light is connected to and which the cool white. Usually these are the WW and CW channels, but you can also choose two other free channels. The remaining channels stay free, for example for more lights.

4. Configure

  • Name and icon for the tile, for example "Bed light".
  • Fuse: at which current it switches off and how quickly: fast, normal or slow (time-delay). The highest selectable value results automatically from the current still available, up to 20A in total across all channels.
  • Voltage protection: undervoltage (UVP) and overvoltage (OVP) protect your battery, simply activate them.
  • External switch: whether a wall push button or a switch is connected to the channel.
  • Wireless push buttons: which buttons on your paired wireless push buttons switch this light, several too, for example at the entrance and at the bed.

Setting voltage protection, external switch and wireless push buttons

Done. Your white light appears as one tile with brightness and colour temperature, operable with the wall push button, the wireless push button, the SmartKnob and in the dashboard.

Good to know: what WW and CW mean exactly and which widget type suits which strip is explained in the article "RGB, WW, CW: what the abbreviations mean".

Related questions

What can I control with Lighty?

Lighty controls all the lighting in your camper over 5 independent channels. Everything is possible, from a single white strip to full RGBWW lighting with colour plus warm and cool white. Or you connect up to five individual lights, such as kitchen, bathroom, bed left, bed right and outdoor light, each on its own. You set colour, colour temperature, brightness and entire light scenes just as you like.

Does Lighty work on 12V and 24V?

Yes, both without any changes. Lighty works in the range from 9 to 36V, so it is just as much at home in a 12V panel van as in a 24V motorhome.

Do I need a SmartKnob for Lighty to work?

Not necessarily. From firmware 0.4.7, a new Lighty responds to its push buttons straight away, without any setup. With Lighty Extension, each of the five push buttons switches its own channel. A short press switches, press and hold dims. With just one push button and no Lighty Extension, you switch channel 2. Even if your SmartKnob ever fails, your push buttons keep switching and dimming. The SmartKnob adds colours, white light (warm white and cool white as one light), scenes, the dashboard, automations, the wireless push buttons and the double tap for all lights.

How is Lighty connected, and what is in the box?

Connection is deliberately kept simple: power and light channels go into high-quality Phoenix lever terminals, almost tool-free, safe and reusable. You wire the push button to the supplied pluggable spring terminal connector and then simply plug it in. In the box you will find Lighty, four mounting screws and the pluggable spring terminal connector for the push button.

Which LED strips work with Lighty?

Lighty controls single-colour and multi-colour LED strips with shared colour channels, meaning normal single-colour strips as well as RGB, RGBW and RGBWW strips. Addressable pixel strips (such as WS2812), where every LED is controlled individually, are deliberately not supported. Lighty is not designed for them.

How many metres of LED strip can I connect?

What counts is not the length but the current: Lighty handles 20A in total. For example, a COB strip with 14W per metre draws about 1.2A per metre at 12V. Two strips of 3m each come to roughly 7A and fit easily. Several strips may also share one channel.
