Hey there, For my new tank I'm not sure what lighting to go for. I was highly considering the realux T5 all in one jobbys, getting 2 x 35". I am a little worried about the fact that once the light blows you need to throw the whole thing away. If it comes with a years guarantee then it's fine, but otherwise I'd prefer to get something that will last a little longer. I wasn't sure which way to go T5, HOT5, T5 HO, high-lite T5, T5 PC or T6... Then I saw this:- http://cgi.ebay.co.uk/ws/eBayISAPI....m=160170359250&ssPageName=STRK:MEWA:IT&ih=006 I asked the seller the following questions:- Hi there, How long are the actual T5 tubes which go in the luminaire? Are there separate switches for each light? Are the T5 bulbs linear or the power compact variety? Sorry last question, can the luminaire use the new high output T5 lights? Thanks The reply I got:- Hi, 39W is high output already. U canÂ´t dim them, length is standard. Rgds Jerry I'm a bit hmmm, I don't think he quite understood what I meant. But for a potential Â£16 maybe I could afford the risk!!! What do you guys think?
