This 400 Watt Metal Halide Lamp produces a strong output of the blue spectrum, which will promote strong vegetative growth and plant growth. This blue spectrum is most needed by plants for rapid growth. Metal Halide is the best type of light to be used as a primary light source (if little or no natural sunlight is available). If you are growing leafy plants such as lettuce or herbs then a Metal Halide bulb is sufficient. Metal Halide lamps can be used as the primary light source to grow plants from start to finish. This is a mogul base bulb and does not fit in standard light fixtures.
