The ORIONIS 2 ft. Track Kit showcases two easily slid able, square, super-slim, and super bright and energy efficient LED modules mounted onto a low profile track. Also included is a 12 volt plug-in power supply. The track includes a touch on/off/dimming switch that memorizes the last setting used. Two screws (included) are all that is needed to attach the track to the surface. Wire clips are provided for easy wire management. Multiple Track Kits can be linked together to expand this LED system, but note, the entire system cannot exceed 15 watt. Built In LED 6W. cULus
