Just a couple notes I feel should be added here.
1, exelent info link but it does show that compard against MH lighting to acheive the same amoun t of light T5's will cost more to buy and will cost more to run. So there is no cost benifit when compard to MH.
2, the T5's that are being hyped are not the same T5's you can buy in a hardware store, but rather a HO version of the T5. I think a standard T5 for a 48" bulb is rated at 28 watts, but the HO T5 that the aquarium industry is trying to push now is a 54 watt or higher tube. same idea as NO T12 and VHO T12.
I have looked into the T5 stuff and as it sits right now you can get the tubes and such from some lighting places but they are not easy to get or cheep enuf throught comercial lighting suppliers at this time to make it worth the trouble as they are not ordering a large enuf amount to get the good price breaks.
I am thinking about bringing in a couple to try on the bottom tank as the PC's on there will need to be replaced pretty soon. This way I will be able to do some testing on the PAR output of them against other types of lighting.
