I've got two on our AGP. The Aqualuminator and Nitelighter. The AL does a decent job of lighting up our 33' round pool. It also acts as a pool return and came with a nice fountain attachment. I installed a three way valve so I can adjust the flow between the two pool returns.

The Nitelighter installs under the top seat of the pool and comes with a standard electrical plug. We use it only on occasion. The cord tends to get in the way of lawn mowing and trimming.

My only problem with the luminator was the non standard plumbing fitting they use. They make you buy a "Hard Plumbing Adapter" if you intend to hard plumb your returns with rigid PVC pipe. The only place I could find it was online and it cost $10 dollars to get it delivered. It's a .25 part.

If you intend to install it on a permanent pool it does need to be wired to code. Our is wired thru conduit to a sub-panel in our storage shed. Otherwise it just comes with a cord for plugging into any outlet.
