I'm getting ready to install lights in my 42 x 32 x 12' 4.5" shop and I like the CFL lights but the high watt bulbs are large and hang down low. I'm installing a Bendpak 2 post lift and when I raise a vehicle on it I don't want to worry about hitting the lights with a car. Would you guys recomend installing the T8's or the CFL's off to the side of the lift? What is more efficient between the T8's and the CFL's? Thanks, Bedrok
