For small installations, where manpower is needed, we have the Mundosoft STICK-GU2, a 128 DMX channel controller in one area, which is pre-programmed with RGB effects and can be programmed with Easy Standalone software.
You can manually select the color and light level (Dimmer). It has a push button "on/off" which acts on their lights and/or DMX receivers.
Specially indicated for small areas control; restaurants, retail, windows, etc.
