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.

Mercury Vapor:

  • Uses a small amount of liquid mercury sealed in a quartz tube with argon gas

  • Produces both visible and invisible UV light.

  • Used in street lighting, parking lots, general flood lighting, and places where long life is not required and color rendering is not critical.
