Find 100 - 1000W Metal Halide bulbs from top manufacturers including Sunmaster, Eye Hortilux, Philips, Sylvania, Radium & Ushio
Metal Halide bulbs produce a strong output of the blue spectrum, which is beneficial for both horticulture and aquarium applications. The blue spectrum is most needed by plants for rapid growth. It's the best type of light to be used as a primary light source (if little or no natural sunlight is available) and can be used as the primary light source to grow plants from start to finish.
Aquarium bulbs range from 6500 - 20,000K, with 10k bulbs emitting a crisp white and 20,000K providing the bluest light.
