The EarthLED LumiSelectTM MR16 XACT Beam Lamp allows for high powered LED lighting in MR16 fixtures while maintaining full dimming capabilities. It uses a 3x2 watt LED light engine to produce light comparable to a 40-50 watt halogen lamp using only 6 watts of power. The beam angle of the lamp can be changed from 45 to 25 to 15 degrees in the field, providing flexibility.
