LEDs and Halogen lighting are pretty much your choices in pond Lighting. Each has their own advantages, LEDs are usually more expensive but use less energy whereas Halogen lighting is generally less costly but they are a little more energy demanding. I cannot stress enough that you buy underwater or landscape lighting from trusted manufacturers such as Alpine, Atlantic, Aquascape and Pondmax. I recommend these because they are very good companies and they design their lights to last. Click on one of the links below to get started.
