24" Ray II on a 37g

Would this fixture (24" Ray II) be too much on a 37g tank? I really like how compact it is. The tank dimensions are 30" x 12" x 22" and my substrate is about 2 1/2" to 3" deep.

My light currently is a Coralife 2T5NO and a 30" T8 strip light that came with the tank.

I'm aiming for medium lighting as I am not running pressurized CO2 and 1/3 EI dosing.

Here's the tank with the current lighting minus the T8 strip light:

Check this thread they have some par values for them.

cause your tank is so high it might work very well

Thanks NWA,

I've been reading that thread and it looks like I'm on target (30-80 PAR) for my lighting needs but wanted to be sure that this one fixture would be enough.

Assuming par values are accurate you should be golden.

I just ordered an original fugeray for my desk pretty excited to get it in

Do you happen to know if the legs slide out? I have a glass lid that it could stand on, but it would be nicer if I cans slide it out to the tank edge.

Thanks!

If it is like the Ray2 it should slide out, that is what I have.

I ordered this light for my 38Bow (almost the same dims as yours), but I will be injecting CO2.
It should arrive tomorrow...can't wait to fire it up and see the light.

BTW...your plants look great.

Thank you syzygy9! If you don't mind, can you post pics?

Thanks!

You want pics of just the light or of it on the tank? I ask because I'm spending the long weekend tearing down the tank and then rebuilding it with all new stuff (including this light) so tank shots would probably be Monday.

After your rebuild. Good luck!

Hey there. I appreciate our fellow users helping him out in my absence!

To address your query, you're probably looking at good medium light for your application. The FugeRay may be a bit on the low light side and I'd hate to risk your plants because of it. Saying that you had 2xT5 and a T8 would lead me to believe the Ray II would be more ideal than the FugeRay

It just came and is even smaller than I imagined. It's very nice looking, but I will likely either paint the gray end caps black or machine new ones from aluminum and send them along the next time I have to get something black anodized.

The legs do slide out to adjust, but not a huge amount. The fixture itself is 23 5/8" long and the legs look like they could extend out to maybe a max tank width of 26". This doesn't matter to me as I'm just setting it on my glass top.

The light color seems great...I'm not perceiving any yellow (I got the 7K/7K version). The light spread for each LED is also very impressive. I put my hand directly against the splash guard to block the light from numerous LEDs and expected it would create a giant shadow on the floor....nope. There was a vague dimming affect on one side, but I had to look for it.

Sorry for turning your thread into an improptu review...I'll try to post some pics in a few days.
