54 x 3w cree led diy fixture

[fishman1]

I found this fixture and it is diy and contains a 2:1 blue:white ratio and is 36"x10" They are also dimmable the seller was asking for $300 and has 2 of these fixtures I was wondering if this is a good price as I'm new to leds and don't know much about the. Also I was wondering if this would be enough light from a single fixture for a 72" long 18" wider and 24" tall tank? It's for tropheus and I figured that the saltwater people would know more about leds. Also since I was going to use it for tropheus should I dim the blues and make the white brighter? Also can you replace the blue for whites?

This should probably go in the aquarium equipment forum . . . but either end of your 72" tank will be dark with this fixtrue.

If its for a fresh tank you really don't need blue in it maybe a few for night lighting, and 1 fixture won't be enough for the whole tank like said already it will be dim/dark on the ends look into the DIY led kits I believe rapidled.com is a site that sells them and have instructions on how to put it together you may come out cheaper that way as well

Okay thanks and I thought this was the aquarium equipment forum?

You need more white LEDs for tropheus.

Blues hurt their color IMHO.

Also, LEDs are very directional even with no optics.

For 300 bucks you can find some really good used 72" fixtures.

Used led 72" fixtures?

for $165 you can get a pair of brand new MarineLand Double Bright 36-48in LED fixtures. You don't need super powerful LEDs designed for reef tanks. your wallet and the fish will thank you.

54 x 3W LED is quite a few of them for a 36" fixture expecially considering you arent growing plants/corals. You could probably invest that much in a more suitable fixture. depending on how they were installed, changing out emitters may not be easy and i they may not be wired so that you can dim the different colors independantly of one another.

but aren't those only 1w leds?

find a place with a leanient return policy, i havent heard many good things about this fixtures but that has been mostly by reef and planted tank guys...they may be fine for what you are doing. they make a reef version too that uses 3W but then again there are blues present.

Why does that matter if you keeping tropheus?
