Hygrade™ hydroponic HPS lamps incorporate a combination of solid sodium, mercury, and xenon or a neon/argon gas mixture within an arc tube. This combination of metals and gasses produces an orange-white light with a luminous efficiency that is much greater than its mercury vapor or metal halide counterparts.
Hygrade™ has been a trusted name in commercial and industrial lighting for more than a century. From fluorescent and compact fluorescent lamps to high intensity discharge bulbs of every description, Hygrade offers a variety of cost effective, energy efficient products for virtually any commercial application.
