LED Power Draw Question
(OP)
Hey everyone, I am purchasing this LED head light for my motorcycle. This website gives 2 different wattages (low/high beam maybe?). I'm confused because non of those numbers match with ohm's law formula of 36 watts. Can someone explain this to me?

It's likely close to the "3 A" specified.
You're right, the specs are all over the map.
