Help me decide Photon fixtures
Hey All,
My old LED fixtures power supply/controller finally gave up the ghost after many years and they are no longer available. So I have decided on replacing them with Reefbreeders Photon fixtures. My tank is a standard 90gal 4ft long that has some LPS and SPS in it. I have the LPS moved out towards the corners/ends of the tank to help keep them from getting too much light. My question is, should I replace them with 2 16" Photon fixtures, or just go for the 48" Photon? With my current setup of 2x16" and the way I have them hung over the tank, I can move them side to side if needed, but if I get the 48" I won't really be able to do that. I know I can get great coverage of the entire tank with the 48, but I worry that I might bleach out the LPS if I have to up the intensity for some SPS. Here's a pic of how I have the current fixtures set up:

My tank is 48 long and 24 front to back. I have the Photon v2+ and like it. The coverage is perfect and I position my corals up or down to depending on light needs. They are very nice looking and you would not really need a hood.

Today I can move the fixtures left and right a bit and adjust how much light the corners are getting. The hood/canopy is decorative so it'll be staying.

You should use the 32" model.
That leaves you 9" on each side, actually even less since the cord come out the end & it has to be accounted for on spacing. I have 2 over my 72" tank with no problems.

The fixtures in the picture above are about 6" off the water and while the V2 is thinner, I'm sure I could eek out a couple more inches since the V2 is thinner than my old fixtures.

All I can add is that I have a 48" tank with the Photon v2 8" off the water and it works for both sps and lps with good coverage and no noticeable light spill. Ron Reefman had a 60" tank and had great success growing all types of corals using the 50" Photon v2.

If u use the 48” model u can use the legs that come with it & do away with the pvc u have your lights hanging from. If u want the fixture a little higher then the stick legs then u can place a board on each end similar to what u have now & let the legs sit on top of the board. I don’t have a photon, but if I was in your shoes I would just get the 48” model

I couldn’t edit my post but with the 48” u can use the legs, have less wires to hide & only have to program one fixture instead of two. For those reasons I would get the 48”. The only time I would get two is if I had a 72” tank.

I am currently using the 48" Photon 2 over my standard 75 gal tank and it will work great on your 90 with no shadow from the center brace. I also had a canopy with 2 AI sol blues before, but since I swapped to the photon I removed the canopy so I could place my lights higher since I'm running about twice the amount of LEDs now and I didn't want to bleach my lps on the sand.
