3-Channel RGB Knob LED Controller

This compact RGB LED controller allows easy manual control of colour and brightness using a simple rotary knob. It is designed for constant voltage RGB LED strips and is ideal when you want straightforward colour control without needing apps, Wi-Fi or remote controls. The controller can be neatly panel mounted into walls, furniture or custom joinery, so only the knob remains visible. This makes it particularly suitable for professional installations where a clean and discreet finish is required.

It is well suited for hotels and hospitality projects, where it can be built into bedside panels, headboards or feature walls so guests can easily adjust the lighting colour and atmosphere. It also works well in offices and meeting rooms when installed in wall panels or furniture, allowing quick colour changes during presentations or events. In retail environments it can be used in display cabinets and shelving so staff can adjust the coloured lighting on the spot. It is also popular in residential projects for feature lighting, cove lighting and media walls where simple manual control is preferred. Bars, restaurants and leisure venues often use it when they need quick colour changes without any technical knowledge required from staff.

The controller uses a standard 4-wire RGB output to connect directly to any constant voltage RGB LED strip, with power supplied separately through a 5-24V DC input.
