Installation Notes

Mercury vapor HID lamps must be installed by a qualified electrician in accordance with NEC requirements for high-intensity discharge luminaires. Always de-energize and allow the existing lamp to cool completely before handling, as operating temperatures are extremely high. Mercury vapor lamps require a ballast matched to the lamp wattage and type; verify ballast compatibility before installation. Dispose of spent mercury vapor lamps in accordance with applicable federal, state, and local regulations governing mercury-containing devices.
