Will this led light be enough

Would one of these be enough for a 90 gallon 48x18x24 ??

Sps lps zoas

Also, is it a decent light? uploadfromtaptalk1459256109682.jpg
 
Considering that this is an all white/blue LED fixture with very little in the way of violet spectrum, it may be OK for a FOWLR tank, and possibly even some undemanding soft corals like zoas and mushrooms.

Perhaps even some LPS might do OK, but that's iffy. SPS like acropora, unlikely.

I was thinking of running 2 supplement t5s uv and something else
 
There is no UV in that fixture. Manufacturers often re-label "420 nm" diodes as "UV" because it helps their sales. But 420nm is well outside the UV spectrum. Moreover, the particular fixture in question has 4 420nm diodes out of a total of 99 diodes. Considering that diodes in the sub 450nm range are very inefficient with respect to their ratio of input power to radiometric output, I'd suggest that the 4 420nm diodes are there just for show.

Bottom line, the inexpensive way to light your tank is with T5HO. Functional LED units, even off-brand "black box" units, are considerably more expensive than the "tried and true".
 
I'm not sure if I agree with you about inexpensive way to go is T5HO, for mixed reef tank he's probably going to have to go with something with 6 bulbs at a 48" length. A decent fixture is going to cost him $300+, then $25-$30 per bulb, so that's another $150+, so you're looking at an easy $450 right there. Then add the annual bulb replacement of another $150+ each year.

Black boxes are tried and true - not going to argue this, but just look at the tanks out there that is lit with them. I don't use them myself, but they work as I seen in numerous times. So, he could go with those $100 black boxes, get 3 units to get the coverage he needs and be better off in the long run.

just my 2 cents...
 
Perhaps, but $450 + $150/year will look pretty inexpensive once the person determines that he/she's going to need to replace said $300+ in light fixtures with utterly inadequate sub 430nm spectrum. Or they figure it out after having lost a few hundred to a couple of thousand in SPS colonies.

That said, just about any light source of sufficient intensity will work perfectly well to keep unchallenging genera/species such as the lower light softies and some LPS now matter what the spectrum. But I wouldn't try it with a bunch of pricey acans and scolymias.
 
I agree with the Mars Aqua and if you have two none of the light will get block by the support.

No clue personally but I would guess that light fixture is only about 32 inches in length. Which will not be enough coverage. You could get 2 - 165Watt Mars Aqua's and have great coverage on a 4ft tank since each 165watt covers a 24x24 area. It really depends on what you want to grow and what features you can live without. There is no Timers , No Ramping, No Wifi on the Mars Aqua. You can always buy timers also to control the 2 channels of lighting.

If Ramping the light fixture * being able to simulate sunrise and sunset* and Wifi is important to you. Then I would say 2 of these would do great.

Also it looks like the lights you were looking at has ramping ability. I would how ever go with 2 of those like this...
