The Garden HighPro LumaxPro HPS Lamp - 400W is a bright lamp, designed for optimal photosynthesis. This lamp features an optimised light spectrum for photosynthesis, making your plants happier, and allows them to grow better indoors. These lamps are designed to be used with magnetic and digital/electronic ballasts and any type of reflector or cooling hood with an E40 lamp holder.

HPS bulbs are the most efficient bulbs that are commonly used by the hobby gardener. They are high in the red and yellow parts of the spectrum and low in the blue, this imitates the fall sun. Because of this spectrum some plants that are grown with HPS lights only can grow elongated and rather leggy, while many other plants are not effected by the light spectrum. For plants that normally bud and flower in the fall this is usually the light of choice because the light spectrum promotes flower production.
