Guess you found my bulb type FAQ from www.acurainspired.com huh?

 

Yes I did, very good information. I couldn't believe nothing like this was here already. Or at least I couldn't find it.

 

There was a FAQ on this site about bulbs, but it was far from complete. Now the FAQ aren't even up anymore. Glad the information was a help. I posted the same thing on here once, but I guess it was deleted or something <shrugs>
