Metal Halide lamp produces powerful light in the blue spectrum, perfect for growing plants. This lamp will run hotter than a sodium lamp, and is something to keep in mind. The lamp can be used right up until flowering as soon as plants are established. For best results, switch to a sodium or mixed spectrum lamp when flowering and fruiting starts. Long Life Has an average life of 15,000-20,000+ hours, more than ten times that of incandescent. Better Light Quality The output of metal halide lamps is closer to natural sunlight than most other light sources. People prefer white light because of better visual acuity, even at lower light levels. Metal halide lamps can be designed to produce almost any color temperature desired, from 2700K to 20,000K. Specialty colors, including blue, green, aqua and pink, can also be produced.
