I have a boat load of halogen spotlights with various wattages and also quite a few Cree led spots that use multipule
cree's. I am trying to come up with a "rule of thumb" efficency comparison watt for watt, so if all things were equal
and compared to the typical halogen spot, what wattage HID would it take to equal a spot with a 50w H3 bulb. Same
with led/cree, what wattage would it take to equal the 50w H3 spot?
