LEDs Change The World DIMMABLE LED Spot GU5.3 MR16 12V AC / DC 6,3Watt genuine warm white 2700K silver coated aluminum housing replaces at least 35 watts halogen with Nichia LEDs
35 watts are realistic at 6.3 Watt LED, very pleasant warm tone, for any 50 Watt (touted), it unfortunately is not enough still top for 50 watts, I would choose one with 8-10 watt LED.
