Replace the lamp and check to make sure the fixture is properly connected to 120–277 Vac, 50/60 Hz power. Consult all applicable codes before installing. Check fixture label(s) for the correct power requirements and supply the correct voltage from a suitable, protected (fused or breaker), and grounded power source.

RLM Xtreme Fixtures: Remove all power wires (black, white and green) from all ballast(s) – let ballast(s) sit with no wires attached for 30 minutes – this will allow a failed ballast to “reset”. Note: both white and green wires can carry just enough transient voltage to keep the ballast from resetting, so it’s best to disconnect all ballasts.

Replace the lamp and check for proper line-in voltage from your power source.

Ensure that all wiring and power source is properly routed. If that doesn’t work, try to replace the lamp ballast. All power-in wire gauge and switch ratings must be in accordance with applicable codes. Power must also be switched at all install access points with a properly rated, SPST interlock switch to completely de-energize the assembly when its install location is accessed.

Ultraviolet bulbs should be replaced annually if operated continuously (recommended) or after 9,000 hours of use if operated intermittently. Replacement bulbs must be the specific size and wattage as originally supplied from the factory. Note: Although the lights may continue to generate a characteristic blue glow beyond 9,000 operating hours, the ultraviolet radiation emitted by the bulbs degrades over time and will no longer provide the intended benefit.

UV lamps should be treated and disposed of the same as other mercury-containing devices, such as fluorescent bulbs, according to local regulations. Low-mercury bulbs often can be discarded as regular waste; however, some states and local jurisdictions classify these lamps as hazardous waste. The U.S. EPA’s universal waste regulations allow users to treat mercury lamps as regular waste for the purpose of transporting to a recycling facility. The National Electrical Manufacturers Association (NEMA) maintains a list of companies claiming to recycle or handle used mercury lamps at www.lamprecycle.org
