I spent if I remember correctly about $110 on some submerged pond lights. It was one cord, with a plug, then a little box with a light sensor so the lights turn on automatically after dark and shut off when the sun comes up and two lights at the end about 2 feet apart. I put one just under the falls and ran the cord up the falls into the pool at the top where I placed the other one. I loved them! Really nice at night. About a week ago they quit working and I don't know why. :( I pulled them out and now they are just sitting there waiting for to decide what to do.

Here is a picture with the lights on.

i have pond lights and they really look great at night.harbor freight sells some cheap ones.or the new way to go would be with led.the negative is you have to keep the lens clean of algae.
