DX18 Hybrid T5HO Dimmable Fixtures (lamps not included). The ultimate way to have both T5HO and LED lighting over your aquarium, the Aquatic Life DX18 Hybrid Fixture provides the platform for you to create the ideal lighting for corals and plants. With decades of experience growing corals and plants, seasoned hobbyists have realized that a combination of different light types works best over their aquarium. Like the metal halide lights of years ago, LED fixtures can provide high intensity, but without the operating cost. Also, like halide lights, LED’s are a point-source light, creating a shimmering effect in the aquarium. Combining LED light with T5HO fluorescent light provides the benefits of efficient intensity and diffused lighting – meaning no more shadows often seen with only LED lights. The patent pending Aquatic Life Hybrid fixture provides a means for you to combine your preferred LED fixture with controlled T5HO fluorescent lighting.
