    Hi guys, need some advice on lighting my 7ft (2m) tank with T5's.

    I was thinking of getting 5ft 80w T5's but then I'm going to have 1ft on either side with no light.

    Question, will a 54w T5 penetrate and emit the same amount of light as an 80w?

    I could go with 4ft tubes, end to end but with a slight overlap in the centre of the tank. Kanga, draw a pic.

    I don't know what I should go for, maybe 54w as they seem to be much more readily available than 80w's.

    Good Boy. Yip, that's pretty much how I want to do it.

    I don't know, not too sure if 39w will be strong enough, I want uniformity throughout the tank and I think the 39w might not be strong enough.

    Yes, going to make up a suspended wooden hood.

    Um dean, I think 39w will be as strong as 54w...it's the same watts per cm so don't see why is should be less effective...maybe Obi-wan can confirm.

    Now that sounds great. You just wanna use your new toy hey :p

    That's what concerns me, I don't know if they work like that, would love some confirmation on this, PAR readings ideally.

    Ok, thanks SIMS.

    Mr Viper sir, why not go 4ft and 3ft together, slight overkill, but hell it would be sweet, even go 4ft T5 10 000k and 3ft T8 actinic if you worried about cost
