i had been searching for a t5 fixture that was really low profile..... 3 inches or less. i wanted a 4 bulb fixture with a good built in reflector and i think i've found it. t5s seemed to be the way to go and now that hagen makes a t5 power glo i think i'll be pleased. here is the link:

its 244.00 and has a good reflector while only being 2.5 inches tall. that gives me plenty of clearance in my canopy.
has anyone ever used this company or can you recommend a better fixture with low clearance? thanks
happy holidays!
