I just recieved my Coralife T-5 series double linear strip from BigAls.com All I have to say is WOW! I never put much thought into T-5 lamps as they are much slimmer than regular flourescent bulbs. I figured that less surface area meant less light output but it doesn't seem to apply, really. Very bright with a good healthy, full spectrum. Anyway, the two lamps combined in the strip are creating about half the heat of one flourescent the same length.
The BEST thing about this light strip is its dimensions: 46.25"L x 3"W x 1"H they also make 36" 30"and 24" as well as some "mini" models for tiny tanks. Each different unit still remains 1 inch high and 3 inches wide. Thats TINY!!!!
