i know the fluorescent are a huge favorite of body shops and detail shops cause they are cheaper to buy and run versus halogens but you have to be very selective when picking your bulbs. without a high enough C.R.I. or kelvin temp. there will be a huge difference when car is out in sun. C.R.I. should be 93 or higher and kelvin temp 5500.
i was also looking to setup lighting in my garage for detailing purposes and called about 20 different lighting consulted companies and they all recommended to go with halogens. they are a truer replica of the actual sun. but if you still want to go with flourescents check out this site. it will explain alot so you can mke an educated choice. if i had the money i would have bought lights from this site. but the 2000 watts of halogen light that i have now works great
