well, i have been holding on to my pc actinics for long enough, and finally decided to switch over to T5 for actinic suppliment instead. i was running eight 65 watt actinic retro kits on my tank, and decided to switch over to eight 24" and four 36" high output T5 bulbs. i went to workhorse 7 ballasts for this - three of em. the bulbs i chose are the URI super actinic that supposedly put out 40 watts on a 24" and 65 watts on a 36" if you have the ballast power to do it. so if that is true, i am now running 580 watts of T5 lights. here are a few pics.

i used solartube material to make the reflectors.

tank with PC actinics


acrylic shells i built to house the T5s


the two configurations i used

2 X 24"

a 24" with a 36"


one side installed (looks the same on the other side of the tank) they BARELY fit! :o


cruddy full tank shot with the T5s - with the PC lights, my camera wouldnt go faster than 1/6 of a second exposure, where with the T5s, it was set at 1/30 of a second - translation, the T5s are WAY brighter
