thanks jenifer....they are 48" t5 bulbs,though while im building my new canopy for the icepa 660 5 bulb setup im still using my home made t12 canopy.... but i'm not in a huge need for bulbs being i only have inverts and LR and such,i should get this new bulb on friday they said anyways,if it's packaged the way it should be and is broke again i might give them another chance but if it's packaged the crapy way it was before then i'll be getting my money back....paid though paypal and it is a bit easier to get money back that way,thanks again though jen,once i get fish again and corals soon then lights are more of a must and i might take ya up on the offerHey Mario, What size bulb was it? I have two strip lights that are on my empty tank you can borrow until you get yours in, that is since I really don't think my tank is going anywhere.
