Good Quality Product By Jim on 7/9/13
Jim would recommend this product to a friend
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.
