In other words, your better off going with 55 watt hid's because you get all the wattage in light output instead of light+heat in the 35 watt hid's.
Thoughts? True or not? Anyone that can test this in their car if You have aftermarket hid's?

Headlights are basically just a simple DC circuit... Think V = I x R and P = V x I
The 35W lights should have higher resistance which means lower amps. Power is thus reduced because the amps are lower, the voltage has stayed the same (nominally 12V).
However, in the grand scheme of things, it's almost irrelevant. Saving 20 watts x two lights is 40 watts. 745watts per hp, so you're saving a whopping .05hp by switching lights. I'd rather have the better lighting.
