Light Spectrum(controlled by 2 channels): Blue 430nm;Green 500nm;Red 620nm;Warm White 3500K;Pure White 6300K;Cold White1000~15000K
90 degree and 120 degree mixed Beam Angle,30 degree secondary optic lens
Plug Standard: US Plug
Material: Aluminum and Iron housing, glass lens
Working Temperature: -20~40 Degree Celsius
Recommend Height above Water: 12"-16"
Recommend Lighting Time: 14 hours on,8 hours off
Recommend tank Size: 24"x24"
Lifespan: 50,000~100,000 hours




Two light modes
Two On/off switches and two control knobs control separately
Channel 1(60 LED): Blue
Channel 2(60 LED): Red,Green,Warm White,Pure White,Cold White
Rotate dimmer to adjust light intensity in the tank

1080 watts of LEDs :eek2:....probably severe overkill IMO...

I say that considering I had 240W of LEDs on a 72" 120G tank and was able to grow corals just fine..

I would just stick with 3 x 165W Chinese black box fixtures..

well I want to make sure I can grow sps. did you have a 5 or 4 ft 120? the 180 is 72x24x24.


the depth is about the same between the two.

I guess it was really a 125G.. 72 x 18 x 24

I think 3 x 165W is plenty on your tank even to grow high light demanding SPS..

missed that. dyslexic. haha :wildone:

I wonder what the height was? that is what I was most concerned with especially since I will be getting SPS. That is my next question. Did you have SPS (acros monti etc).

Sorry.. edited my post after to include a bit more..

And FWIW.. A very generic rule for determining how many watts of LEDs you need for SPS is to multiply the tank length x depth x 3 divided by 16
So 72 x 24 x 3 / 16 = 324 watts
So 3 x 165 = Plenty..

perfect!! That is the question answered! that is a good rule of thumb. As for the three fixtures, I wanted to make sure I got good coverage across the whole tank. In addition there wasn't a big difference in price between the 165 and the 360
