Oh, the horror...
@1995z71: My lenses are pointed down, really. Nobody will be blinded unless I get right up behind them. It's actually so bad I really need to adjust them. More like 20" from the bumper is the top of the light beam hitting the road surface. Besides that, 15% difference in brightness isn't that much. I want to be able to see off road without putting a lot of giant light bars on.
@poncho62: Not sure about that blue coating, I think it dims the light slightly. I went with clear bulbs. Philips Rally Vision 9005's are 100w and the 9006's are Hella 80w.
I will consider those lenses on ebay. I dunno, maybe too bright then.
a 63.25 watts bulb would be 15% "brighter" on the the low beam, 74.75 watts would be 15% "brighter" for the high beam bulb...as you say......your math is incorrect.
