A battery operated LED-projector, a 15Watt RGBW LED has been used to avoid unwanted color shadows. For many applications exhibition booths, parties, special events and more. Great way to up light bottles and glasses. Eight hours use in 3 color fading mode on a fully charged battery. Each projector is equipped with a wireless transceiver module. This projector can still be used with an empty battery just connect it to the mains. Very smooth RGBW color changes thanks to high frequency dimming electronics. The battery charger charges the battery while the projector is working on mains power.
