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
