Hi. I've been viewing this board but just joined and this is my first post.
I've got a 37 gallon tank that I set up a few months ago and just had my 30" coralife lighting unit stop working. Unfortuantely my girlfriend bought me the tank because she knew I wanted one and thought i would be nice but was sold a bunch of junk (including 30" coralife light) with it.

I'm looking to replace it with an LED set up and thought the marineland plant light was interesting. Here's my question:
being that the 37 gallon is 30" long, will the beam from the 24"-36" light be wide enough to cover the bottom? I'm concerned that the light will be quite direct and leave me with a dark perimeter around the tank.

Any thoughts, observations, or suggestions are greatly appreciated.

Thanks!

that 24"-36" unit is 24" long, it will be 3' to short on both sides. I just did the same thing, hated it, so if you do it, save the box so you can return it if you hate it.... you could plant shade loving plants around the edge...

That's what I'm afraid of. It seems so appealing as I could actually try some high light plants but I really don't want something so short.

I'm not familiar with the PAR rating of the MarineLand fixture you are currently using, but the new Finnex Fugeray fixture comes in a 30" width and is rated at 30 PAR @ 18" (a relatively common light to substrate distance for 30-50G tanks).

Here is a link to the PAR data for the different fixture sizes.

I believe the 37 gallon is 24" deep which would give me 17par at the bottom with the 30" light. I don't think thats going to be enough. I appreciate the recommendation though.
