I decided to pick up the ones I had showed pix of. The Hella H4 55W65 halogen bulb showed 3/4 of a volt drop measured with a craftsman volt/ohm meter at the light itself, and had the usual heat radiating off it.The LED H4 showed no measurable voltage drop with the same meter hooked up, and no huge amount of heat radiating off it. The LED beam seemed a little brighter than the halogen and about the same pattern when pointed at the shop door.
