The H37 ballasts are mercury vapor ballasts and they are specifically designed to run the Iwasaki bulbs. I didn't know that when I got them but it was a good deal so it doesn't matter.
Heh, you know if you just scroll down so that you can't see the second photo, the first picture doesn't look all that bad. Of course compared to the second picture now I want 10000K bulbs!
Yeah this poll is prompted by the fact that I'll probably need new bulbs soon. The iwasakis can go for up to 2 years, I usually replace them every 18 months or so but I figure Merry Christmas to me (again)
