Proper disposal of used fluorescent and High Intensity Discharge lamps are important in preserving the environment. Fluorescent lamps provide lighting and illumination for countless businesses, schools, and homes. HID lamps (mercury-vapor, metal halide and high pressure sodium) are used for illuminating streets, floodlights and industrial applications. |

Fluorescent lamps are not as powerful as a High Intensity Discharge (HID) or High Pressure Sodium (HPS) in terms of lumen output and wattages. Fluorescent lamps generate far less heat than HID lamps which makes them a good light for applications with limited ventilation. They also use much less energy than HID lamps. |

High Intensity Discharge (HID) Lamps are electric lamps that generate light in a small arc tube under high internal pressure. HID's are know for their lifetimes and intense light output. These lamps are used for various reasons, including, but not limited to street lighting, indoor large commercial/industrial buildings, stadium lighting, for lighting landscape and for growing plant indoors.
