Lithonia Lighting support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I test my Lithonia emergency light or exit sign?

    Most units have a 'TEST' button. Pressing it for 30 seconds simulates a power outage to check the battery and lamps. If the lamps do not illuminate, the battery or lamps may need replacement.

  • What should I do if my exit sign is beeping or the red light is flashing?

    A beeping sound or flashing indicator often signals a maintenance alert, such as a disconnected or failed battery, charger failure, or that the unit is in a diagnostic mode. Check the manual for specific flash codes.

  • Are Lithonia LED fixtures dimmable?

    Many Lithonia LED residential fixtures are dimmable with compatible triac dimmers. Check the specific product specification sheet or packaging to confirm dimmer compatibility.

  • Where can I find replacement parts for Lithonia products?

    Parts like diffusers, lenses, clips, and batteries can often be ordered through authorized distributors like Home Depot, or by referencing the parts list in your specific instruction manual.
