24” Metal Halide T5 LED Combo light

[PacoPetty]

Would two of these be enough light for a 72” long 125 gallon tank? I would upgrade the bulbs.

3 of those 250W 24" fixtures would work over a 72" long tank.

They make that in a 72” version. Would be a heck of a lot easier replacing 4 t5ho bulbs than 12

I haven't had any luck finding the same fixture in 72". Do you have a link or website info where I can buy it?

Unless you had a reason to choose the 12 bulbs over 4, like you really wanted to go crazy with bulb combos, I would pick the 4 bulb larger system. Two of those smaller ones just won't cover a 6' tank well, would leave a very large gap between with no lights.

You might be able to get away with two of those, if you space them well and place more sps under and lps in the gaps.

That 72 is gonna run real hot, T5s might not do as well.

I'm not planning on having any SPS. I just prefer the MH T5s over LEDs.

In that case you can get away with 2 for sure. you'll be able to raise the two a little higher for more spread since you wont need sps level par. May I suggest 250w radiums

You may not lol. That’s a DE fixture. Phoenix 14k are close though

Thank you all so much for your help! I am going to go with two 24" fixtures and raise them up a little to get a little wider spread. Eventually as the tank matures I would like a Euphyllia garden and a Zoa garden. A nice Monti would be nice too.

Like Bpb said, those are DE fixtures and you will need 3 of those for sure. They aren't the best to offer over a 72" tank to tell the truth. I was assuming you would have a real great deal getting those. Even though, you just can't raise them because of the type of reflectors. They are not designed that way It's not going to work, realistically speaking. Try to search for other fixtures like a Hamilton, etc. Get the right thing for your tank if you will invest. Halide fixtures will basically last forever.

OK, I found this 72” Hamilton light fixture.

 

[YankeeTankee]

Something like this. With LPS only I don't think you need the third bulb. Leaves 6 inches on either side, about right.

That's the one to get.
