What types of lamps contain mercury?
Fluorescent lamps (including compact fluorescent light bulbs) and high intensity discharge (HID) lamps are the two most common types of mercury-containing lamps. Fluorescent lamps are commonly used for the lighting of schools, office buildings, and businesses. HID lamps include mercury vapor lamps, metal halide, high-pressure sodium lamps and other specialty lamps that are used for streetlights, floodlights, parking lots industrial lighting and some automobile headlights. The Northeast Waste Management Officials Association provides information on how to identify mercury-containing bulbs.
