Offered in cool white and incandescent white, drop-in replacement MR16 TrackLEDs have 2-pin bases, draw 2.5 W, and provide 42 LEDs. Four beam angles include 15-20, 25-30, 40-50, and 100-120 deg. LED-sourced MR16 lamps generate little heat while operating and pose no threat to objects they are illuminating. They can operate on clean or dirty 12-24 Vdc power supplies, eliminating burnout from incoming voltages that are higher than lamp's capacity.
