I'm planning to add more T5s to my tank and have researched a number of online and local vendors. Global Aquarium Supply (online) offers the 60" T5 retrofit kit (turn-key) with 4 80w bulbs included for $259, plus shipping.

Does anyone have experience with Global Aquarium Supply? Here's the link: http://www.globeaqua.com/t5_kits.html

How about T5s in the 60" length? Are there any known problems with this length? I'd like to avoid the 48" length because I'd have to buy 2 separate fixtures to cover the 72" length of my tank. I don't have that much space available unless I move my existing lights.

Any feedback would be welcomed. Thanks!
