Most of you know that there are H1, H3, H4 and H7 bulbs, but what about the missing digits? (i think it might skip H6 and H7...i'd have to look) They actually go up to H11, but hardly any of the other bulbs are used (H9 is actually a horrible little 35w bulb that some 2002 mercedes use).
The H2 is the most efficient per watt bulb made that meets ECE code. It produces 1880 lumens out of 55w. (www.lighting.mbz.org). They never became popular because they require a ceramic base, and some other reasons. It was actually intended to improve on the H1 in the late 1960's (H1 came out in '64 i think). Here are pics of the H2s that i took out of my car and replaced with new ones just because the other ones were old. (they are now my spares). Because these bulbs are so rare, i have a hard finding them and finding them in anything but regular 55w (no yellow, no xenon mix, no HID look, no blue...nothing. Not that i want HID look or any of that crap, but nobody makes it...go ahead, look for it. I found one place that had blue bulbs in 100w..yucky and break my lights!). Believe it or not, simply replacing my bulbs with new ones, made a performance improvement...more light!
