    Hi Guys,

    I finally got round to building my ATS this weekend. Everything is done except the lighting. I was thinking of using flourescents as opposed to CFLs - seems more efficient to me. I also have 2 screens so the flourescents will be perfect.

    My question: does anyone forsee any problems using T8?

    Cheers
    Jason

    no problem. T8 is actually better and cheaper.

    Check out the T8 tubes in the "normal" petshops that they use on fresh water planted aquariums. Those they use to get good plantgrowth, high in yellows and reds. If it do work for aquatic plants, then it must work for algae....

    Only thing about the T8s is the lack of power. You want some nice bright light to light up the scrubber. A 25W T8 is 2.5ft long. The CFL 32W is very compact.

    Hey Marius,

    My screen is 800mm wide.......... hence my thinking behind using either T5/T8

    I would probably have to look at a 32W T5 maybe?

    agreed Marius. But for me it is the colour spectrum that is important, then the price. T8 is cheaper that T5. Can have the specific plant grow types. CFL's is better in amount of light. I used 2*45W CFL's, and downgraded to 2*35W CFL's. Cheaper globes.

    Also CFL, it is better to use warm white or cool white. Not day light.

    And CFL must be mouted sideways or pointing up. Else you overheat the balast / base and thereby shortens the livespan of the globe. That is what is promoted.

    But, I rather mount them pointing down and heating themselves, because any water spashes or accidents just drips off the tubes portion, instead of dripping into the base and blowing up the globe. And anyway then the lifespan of the globe is seriously shortened.

    Another question guys:

    I have dual 54W T5 ballasts lying around at home. Can I use these with 32W bulbs?

    Cheers

    Don't think you can use T5 ballasts with T8 globes.

    Its not advisable. The globes will lite up (if you use T5) but since you are over driving the crap out of them, you will shorten their lifespan drastically.

    CFL is "Compact Florescent Lamp". The energy savers we get everywhere. They are the same as T5 lamps. Just compact due to all the bends in them.
