Does it matter which fixture I use to replace a Metal Halide, High Pressure Sodium, or Mercury Vapor?
A number of factors must be considered when choosing the best fixture to replace a Metal Halide. Choosing the right optics is one of the most important. For example, a warehouse that is comprised of ten foot aisles and a large bay area for loading and unloading trucks; the aisles would require a fixture where the reflector used was designed to push the light straight down to the work plane in a more focused distribution. The lighting in the loading area would require a standard distribution. Other factors include: mounting height, wattage being replaced, desired foot candles, color of walls, ceilings and floor, and desired energy savings. Lighting software exists and is made available to lighting manufacturers to ensure the right fixture is used for the specific application.
