I always read danbfree's responses, but just to be clear - I put the (Hella) H1/100's in my car 4 years ago when new.....
No, I'm glad to hear that has worked out for you, I should clarify that I'm speaking in generalities... May I ask how long at a time you have used the 100w high beams? I've just heard that the wiring itself and maybe even the housing plastics themselves can have issues at such power levels, so it's encouraging to hear that's an option... I guess it depends on what you are looking for exactly, I suppose at 100w you could use a blu-ish type halogen and get decent output, but I'd like more of a pure white 5000k with decent throw and output, and I just felt that was safer to do with a lower temp LED.
Also, it is indeed easy to get really bad LED's with terrible glare, but truly effective ones with very little to no glare are indeed available now. Glare is obviously unimportant with high beams too, so that's why I lean towards H1 LED's in that regard, for effective, cheap and cool running... but for low beams it does take some research, you can't just choose whatever random set off Amazon that has high reviews by people who don't care that they are blinding people.
