            NEMA Lighting Answers

            NEMA-Lighting-Answers-IMG-300x265Q. Some LED lamps have integral batteries and chargers, can these be used as emergency lighting?

            No. These types of lamps are usually intended as substitutes for the original lamp in a luminaire and are user replaceable. They are not provided with a means for fixing in place to ensure a permanent installation. Accordingly, there is no protection from these lamps being replaced with lamps not equipped with batteries, thereby eliminating the emergency egress lighting.  These lamps are certified (listed) as Self-ballasted, Light-emitting-diode Type lamps, to UL1993.  The UL guide card for this category (OOLV) states: “These products have not been investigated for use in emergency lighting equipment or exit signs.” 

            UL924, The Standard for Safety for Emergency Lighting Equipment, requires emergency battery packs to have a means for permanent mounting to a luminaire. This ensures compliance with National Electrical Code, Article 700, and NFPA 101, section 7.9. Only products and components that are certified as Emergency Lighting and Power Equipment, to UL924, are suitable for use in emergency lighting systems.
