I just purchased a GLA 36-L (6 gallon) rimless. Dimensions are 15 x 9 x 11 inches. Im thinking of the Fugeray 16" light. .. and since my tank is 11 inches tall.. I plan on probably having 1-2 inches of substrate.. I noticed that these lights have legs on them.. so do you think I would have algae problems WITHOUT running co2?

The legs will give you about 1-2" inches above the rim. To be honest, without knowing your stock, I suspect you'll get a hint of algae at the beginning but nothing a routine dose of excel can't take care of if you're not planning on a co2 setup.

150 gallon light

would a single ray 2 be enough lighting for a 150 low tech tank with low to mid light requirement plants. The tank is 60x24x24.. So by the time you lift the lights up a couple inches and add a couple inches of substrate its still 24" from light to sub.. Would the fugeray be to little light??

Thanks so much for these post! I was going to get the new marineland led lights for my 72 bowfront (medium to high light) but looks like the Ray II has just the PAR im looking for and half the price of the marineland

Your par would be 74 directly under the light and 64, 57, 45 as you go further away from the centerline.

I cant find any data on there being a 30 inch Ray2. Is this true that it comes in a 30 inch?

How do you get those numbers? I thought flipanda was right.

Re: Finnex RAY II & FugeRAY PAR Data

I appreciate all the work and data put in this thread. I just wish I understood it all
What I am trying to figure out is.....
I have a 6' 125 gallon tank that has an older halide fixture. 300 Watts of halide and 90 of florescent.
it is time to replace that fixture.
I was going to do a 4 bulb 320 watt t5ho fixture.
In looking at these.... I got to thinking about 2 of the 32 inch fixtures.
I have looked at the numbers, but am still confused. I am using co2 and would like to continue.
I was thinking that the ray 2s may be the answer, but don't wasn't to order them and be disappointed.
Any help/opinions would be greatly appreciated.

Hey shadetreeme, I think that, while these are excellent lights for many tanks, your tank is a bit outside of what these lights are designed to be used for. They certainly don't make a six foot model. Perhaps 4 three foot Ray 2s would work but they aren't designed to be mounted partway over a tank, and in the center where the light fixtures would meet, your tank would have a dark area. I recommend T5s or some other LED system.

I do use a Finnex Ray, and I plan on getting another one for my next build. I'm very impressed with it.
