opinions on good high pressure bulbs
 

I was curious as to if anybody had any good opinions or information on a great brand for high pressure bulbs, I know I already made a post before about this but was kind of looking for more information on some of the different brands that are available. Does anybody also know how I can get information regarding the different brands on their lifetime and their UVA output? I've contacted a few companies about this information but for some reason I am just getting lifetime information on the bulbs.
