Lithonia Lighting - Lithonia ELM2 120/277v QUANTUM Incandescent Emergency Light Unit, White, 2-Lamp

A slim, LED emergency lighting unit for general purpose applications. Provides a minimum of 90 minutes of illumination for the rated wattage upon loss of AC power. Ideal for applications requiring attractive unit equipment with quick installation. Features: Engineering-grade thermoplastic housing is impact-resistant, scratch-resistant and corrosion-proof.; Features two LED lamp heads with 12 parallel white LEDs in each. The typical life of the LED lamp is 10 years.; Unique track-and-swivel arrangement permits full range of direction of lamp head adjustment.; Battery: Sealed, maintenance-free Ni-cad battery that delivers 90 minute capacity to emergency lamps. - Installation: Ceiling- or wall-mount standard. Flexible conduit entry provision on top of the unit. - Intended Use: Provides a minimum of 90 minutes of illumination for the rated wattage upon loss of AC power. Ideal for applications requiring attractive unit equipment with quick installation. - Electrical: Dual-voltage input capability (120/277V). Edge connector on printed circuit board ensures long-term durability.; Current-limiting charger maximizes battery life and minimizes energy consumption. Provides low operating costs.; Short-circuit protection . current-limiting charger circuitry protects printed circuit board from shorts.; Thermal compensation adjusts charger output to provide optimum charge voltage relative to ambient temperature.; Regulated charge voltage maintains constant-charge voltage over a wide range of line voltages. Prevents over/ undercharging that shortens battery life and reduces capacity.; Filtered charger input minimizes charge voltage ripple and extends battery life.; AC/LVD reset allows battery connection before AC power is applied and prevents battery damage from deep discharge. - Optics: Two LED lamp heads with polycarbonate lens, 12 series-parallel white LEDs each, provide redundant light sources to ensure emergency lighting performance. Typical LED lamp life is 10 years. - Construction: White, compact, low-profile contemporary design. Engineering-grade thermoplastic housing is impact-resistant, scratch-resistant and corrosion-proof. UL94V-O flame rating. UV-stable resin resists discoloration from natural and man-made light sources.; Low-profile, integrated test switch/pilot light. Easily visible bright red status indicator.; Unique track-and-swivel arrangement permits full range of direction of lamp head adjustment. Universal J-box mounting pattern. Tool-less access for maintenance. - Listings: UL damp location listed standard 50-104±F (10-40±C). Meets UL 924, NFPA 101 (current Life Safety Code), NEC and OSHA illumination standards.
