HID (High Intensity Discharge) Basics:


The operational concept of HID lamps are very similar to fluorescent lamps.  HID lamps include Mercury Vapor, Metal Halide, High Pressure Sodium/Low Pressure Sodium (SOX). 



  • In an HID lamp, the electrical arc, gasses and metals are contained in the arc tube.

  • Like fluorescents, HID lamps require a ballast to control the electrical current in the arc tube.

  • HID lamps need a start-up time to reach their full brightness. This usually takes 5 to 10 minutes.


Metal Halide



  • Uses metal halides of sodium iodide and scandium iodide

  • Most popular and widely used in the HID category

  • Used in general lighting as commercial/industrial/outdoor flood lighting where good color and high efficiency are desired
