Well, I bought a complete set of what were supposed to be 55W "super white" H7 bulbs from a vendor on E-bay a week or so ago. They showed up on Saturday. When I opened the box, the bulb container stated 100W 12V H7 "low input". I really didn't want 100W bulbs as I was concerned about damage to the reflector and headlight housings on the car. Anyway, just for curiosity purposes, I brought them in to work and tested them for current draw. Turns out that they each draw 6.4 Amps at 12 Volts, which works out to about 60W/65W output each. So if you've purchased a set of these Chinese "low input" 100W bulbs, keep in mind that they are probably only 60W bulbs (safe for your headlight housings, that's a good thing). I agree with others on this site who are concerned with damage to headlight housings using high output bulbs.

 

they mean "the output equivalency of 100w bulbs" but are really just normal-rated bulbs, as you found out. i think that's what the "low input" means; it won't draw any more than stock, but will "appear" to give off 100w of light power.
