You're welcome! If you have a good LFS with knowledgeable fishkeepers, they should be able to recommend a good series of broad spectrum lamps with the proper wattage for your tank.
I run 8 T5 High Output lights over my 55 gallon reef tank and just use the total watts listed for the bulbs (8 x 54 = 432 watts). To be on the safe side I don't add watts to this total, like how a 15 watt compact fluorescent is comparable to a 60 watt regular fluorescent... I think the T5s penetrate to the deepest levels of the 55 gallon just fine.
How many T5s and what bulb wattage do you have over your tank?
