Yeah bro these lights are not gonna work for your tank, even if you ran 6. That's a big deep tank. I do not recommend the chinese boxes on anything over 24" deep.

I would DIY LED on a tank that size, that's gonna be your only option, or spend some real money on higher quality commercial boxes - which in that case just keep the MH...

Look into DIY perhaps

You can check out my build thread. No complaints with the lights. They work.

They key is making sure you have enough and nothing deeper than 24"

So 4' 24" deep = 2 lights
6' 24" deep = 3 lights

etc

I have 1 on a 3' tank works great!

Depending on the ballast, bulb, and reflector, these black boxes can be close to, or higher par, than a 250 watt MH. For those needing something equivalant to 400 watt MH, they do make these boxes with more power/leds.

How deep is your tank,and do you have the 120w 14k version? If so do they seem too blue to you?

they do not list what kind of leds they are using and what ratio blues to whites. Also they are all listed as using 1 Watt LED's. I think this is like buying a box with out knowing what is realy inside it.

this is interesting if you read the small print and do a little calculations.

first off they are ysing 144 LEDs to produce 300 Watts. That basicly means each led is 2.08 Watts each. Then they are stating that they are running at 300 ma. For a LED to produce 2.08 watts of light at 300 ma it would need
roughly 7 volts per LED. I do not know of a manufacturer that makes a LED that comes even close to specs like that.

Creee does have high voltage line XT-E-HV but they run at a max of 66ma and 60 volts producing almost 4 Watts.

2 would work. But I would get 3.

3 and your set to grow anything.

Maybe they use the same leds as aquariumleds.com? Their specs state 120watt, 40 leds, 300mA. 3 watts per led at 300mA. The aquariumleds, specs say the leds are: Semi/Bridgelux.

Ill prob start with 2 and go from there ... Just dunno if I want the 14k or the 20 k I like a blueish look but the ratio on the 20ks is a litte much I think its 27 blues to 13 whites I believe I wish pictures were more accurate or someone local had these ones to go check out

[BigCountry74]

go with the 14k (50/50). the 20k will be to blue

here are 3 pics from my tank of the 14ks - white only, blue only, then both

also I highly recommend 3 of these lights on your 120g. not sure if 2 will do the job.

Same light, 7% off for 3 of them.

I am not so sure you need to dim these lights though. Nice feature and all, but I think its not needed, unless your running them in a very shallow tank.

I would be interested to see how good they are, esp being dimmable. If that's legit, that's a great deal.

R u reading?
That unit is a 1:1 ratio and it isn't including optics that cost like $0.17 each...

So same website yes but not the same light

[BigCountry74]

Oh sorry. I was not reading that.

I just ordered 2... I'll post pics....
Dimmer for me is so I can get the blue I want and so I don't have to move coral or fixture to avoid burning coral...
Dimmer makes for Good night lighting to..

On the link it doesn't say if it has two power cords. Just says it has 2 switches. I am e-mailing to make sure it has 2 cords. One for white and one for blue.
