    On a 800mm 600 deep cube what lightning options do I have,
    T5 39W is just too long.

    T9 24W at 600 should be OK, then I have to do 10 globes to cover inner 600*600 with 100mm open at the sides (can get my hand in there)

    Or MH, right in the middle, and 4 T5 around it

    Any suggestions please

    Hi Riaan - I would go for a 1 x 150 watt Metal Halide + 2 x 24 watt T5's lighting Unit, like the one I got. You can then add another 4 x 24 watt T5's on the outer "edges" of the T5 unit.

    My unit is 600mm long....

    On a tank that is 600mm deep, so the water will be at about 550-570. So corals etc will at at max dept 500mm and higher up.
    Must I go MH? plus 3 to 6 T5? That is if I can fit that all above the 800mm cube.
    Or should 10 or 12 T5 24w at 600mm length be enough light.

    depending on what you are going to keep, either 1x 250w Mh for maily SPS or 1x 150w for LPS and softies, perhaps 2x 24w to supplement.

    after having 8x 54w T5s on my tank, Mh look much more natural IMO.

    I'm with the guys on this one especially seeing the length of your tank.

    Or how about just 1*250W MH on a Luminarc reflector? That will look cool. Oh yes, and a 14K bulb :)

    Exactly what I have on my 650 cube... everything has coloured up very nicely, but the tank looks just a little too blue for my liking

    Another option I can think off is maybe a 10K 250W MH supplemented with 2*20K T5's. That should break it up a bit.
    PS. High time you post pics of your tank Dave ;)

    I think I will go with Mekaeel suggestion,
    250w MH in the center, flanked by two T5 20000K (one at each side)
    with 4 led moonlights, 2 in front and 2 behind the MH.

    So moonlights will always be on.
    T5 first on, last off, one or maybe 2 hours before MH comes on and same thereafter
    Mh middle period, max 10 (maybe 12) hours.

    Question, what is the physical size of a 250W MH unit.

    How could I forget about moonlights. That will be excellent bud!
    Im not too sure about the size of the reflector Riaan. Perhaps drop Lanzo a pm and check up with him. :)

    The reflector is in the region of 400x400mm

    So that should be fine if placed 25-30cm above water level.

    Pretty much yes. I have mine 15 cm or so above the water surface. These light units give excellent cover and should easily cover 800 mm

    The MH units that comes in those combined MH plus T5 units, Lanzo also have some, why are they a lot more compact?
    Or are they only 70w?

    You can either buy the MH/T5 combo or just the Luminarc reflector and DIY your T5's with decent reflectors.
    The Luminarc reflector is much larger than the combo, so better light distribution.
