Not for Hydra 52's By Ken on 9/1/2014

I jpurchased these for my Hydra 52's and they wouldn't work at all. I finally "rigged" them so they would hold the lights.

The rail system was easy to put together and very light weight. Only thing I would change is the end caps seemed a little flimsy, could have used a stronger/thicker plastic or metal.
Good Quality Product By Jim on 7/9/2013

I had purchased (3) Aqua Illumination Hydra LED Modules for my 150 gallon reef tank. The mounting rails are high quality aluminum, the ends are plastic, but durable. The reason I only give it 4 stars is, I already payed out $1200 for the lights and another $65 for the(48") rail system. Then I needed to order the hanging kit to install it all. I think for the money, the rail system should include the hanging kit. Just make sure you don't purchase the wrong kit. I ordered the EXT Kit instead of the Rail Mounting Kit. But I would recommend this product.
