> This article mainly introduces the relevant knowledge for quickly building General Lighting panel mini-apps based on templates.

#### Number of Channels

Depending on the different white and color light DP support, the lighting is divided into one to five channels.
The meaning of each channel is as follows:

- One Channel lamp (C) : "C" is an abbreviation for "Cool", representing one white light lamp, which is a lamp with adjustable brightness. [related modules] (/en/miniapp/solution-panel/ability/special/lamp/module-set/common-white)
- Two Channel lamp (CW) : "CW" is an abbreviation for "Cool Warm", representing two cold and warm white light lamps, which are lamps with adjustable brightness and cold and warm colors. [related modules] (/en/miniapp/solution-panel/ability/special/lamp/module-set/common-white)

- Three Channel lamp (RGB) : "RGB" is an abbreviation for "Red Green Blue", representing three color light lamps, which are lamps with adjustable color light colors. [related modules] (/en/miniapp/solution-panel/ability/special/lamp/module-set/common-colour)
- Four Channel lamp (RGBC) : "RGBC" is an abbreviation for "Red Green Blue Cold", representing four color light lamps, which are lamps with adjustable color light colors and cold white light brightness. [related modules] (/en/miniapp/solution-panel/ability/special/lamp/module-set/common-colour)

## Development Template

Next, you can quickly start developing General Lighting panel mini-apps by creating a new [project template](https://github.com/Tuya-Community/tuya-ray-materials/tree/main/template/PublicPanelLamp) through Tuya IDE.
