The light has 20,000,000 cp Halogen written on it but it is advertised to be 100w hid. We know it doesn't have 100w at the bulb but it does have a extreme intense hot spot with out much spill. It's not quite as bulky as the Thor lights with only a 6.5" reflector but has a tightly focused pincil beam. It has a fan inside to keep things cool and the battery is easily removed making it easy to change in the field if I only had a spare.
