Metal Halide High Bay Lights have been the standard type of lighting for high-ceiling applications for many years. Their brilliant output, reliability and durability makes them still the number one choice for many types of large high bay environments including warehouses, manufacturing facilities, gymnasiums, barns, gymnasiums and sports arenas as well as outdoor parking lots and other facilities.
Over last few years there has been a lot of attention placed on phasing out all High Intensity Discharge (HID) lamps and replacing them with energy efficient alternatives such as linear fluorescent, compact fluorescent, induction lamps or LED lamps. Proponents of this wholesale shift away from HID claimed low efficiency, poor color, quick lamp lumen depreciation among the failures of HID. Some of the claims were valid for fixtures with magnetic ballasts, also known as core and coil ballasts. Some of the claims do not take into account deficiencies of fluorescent and LED technologies. However, if you include in the conversation electronic HID ballasts with pulse start Metal Halide lamps, particularly Ceramic Metal Halide lamps, HID is still the best high bay lighting solution on the market when all things are considered.
They are especially effective on surfaces at least 20' away from the lighting. Because of the wide spectrum of light they deliver they are also popular for indoor growing operations. Effective lighting is essential for workplace safety and productivity.
