 To my eyes the H18 is ever so slightly whiter and brighter than the H7.
 So far I'm not tempted to make the change especially when considering the higher temps and additional draw on the electrics.
 I guess real world comparisons on the bike may be different though? What do you think?  :027:

 Thanks for taking the time to do this and share.  :028:

Tighten it 'til it strips then back it off half a turn.

I thought the H18 edged it ever so slightly, however, for what looks like it will be a tiny improvement, I dont think it would be worth the extra electrical load. Then theres the heat to consider, from a quick look at the video, seems that the H18 runs about 20C higher. Doesnt seem a lot, but when its an extra 20 degrees on an already high temperature in the small headlight housing, that much difference in temperature could have some negative effects. I may be wrong, but I wouldnt want to test it in my headlight housing.

I did test the H18 in the headlight for a while, it is not brighter even there on idle. It might be brighter when the voltage is more while riding. But the extra 15 - 20 C might cause issues in the long term, I don't think 10 W itself would do a big diffrence. But now we know the H18 is a dead end and cannot be recommended.
