Some ponds require illumination that can only be provided by larger light fixtures. LunAqua 5.1 is such a fixture, which now comes with an energy-saving 80W halogen bulb, that outputs as much light as older 120W bulbs. The LunAqua 5.1 runs directly with 110V which means it can be run without the need of a transformer at all, making it truly a flexible lighting system.
