    In my search for lighting, I came across T4's. Does anyone have a clue about T4's? Is it better than a T5? I really get confused with all the choices.

    Hi Richard

    The T number indicates the size of the tube in eights of an inch.

    T8 = 1inch tubes
    T5 = 5/8 inch tubes
    etc.

    I have never heard of T4 tubes and if they will be any better than T5's.

    Thanks for the heads up

    I have T4 in one of my tanks. Spec as follows

    T4 PL
    Power - 28w
    Voltage - 220 to 230
    Frequency - 220 to 230

    I have four tubes in it; 2 white & 2 blue. It is quite bright and makes a huge difference in my tank as far as plant development is concerned and enhancing fish colour. It is an all-in-one (ballast, holder, reflector, tubes)

    Cheers
    Dale

    Price = Dunno as I paid R 150 for this unit I have (Got it from Kyle)
    Will check tonight for Kelvin rating...got it as it, no box no nothing, so I got the info I posted directly off the unit.

    @icarus - Will confirm later when I'm home

    @turando - The tubes of T4 are thinner than T5 and looks much nicer. On the actual spec between the two, I think we'll have to use our old friend google :)
