FEATURES & SPECIFICATIONS
INTENDED USE — Ideal for applications where steel housings or metal lamp heads are a requirement.
CONSTRUCTION — 18-gauge steel housing finished in instrument tan color.
Hinged faceplate for easy maintenance.
OPTICS — Glass sealed-beam PAR36 lamps in thermoplastic housing, available in incandesent and halogen
lamp types.
ELECTRICAL — Dual-voltage input capability (120/277V).
AC/LVD reset allows battery connection before AC power is applied and prevents battery damage from
deep discharge.
BATTERY: Batteries are sealed, maintenance-free, lead-acid (SLA) with wattage capacities for 90 minutes
of emergency operation. 16-watts (ELT16), 24-watts (ELT24), 36-watts (ELT36) and 50-watts (ELT50).
Current limiting charger maximizes battery life and minimizes energy consumption.
Thermal protection senses circuitry temperature and adjust charge current to prevent overheating and
charger failure.
Thermal compensation adjusts charger output to provide optimum charge voltage relative to ambient
temperature.
Low-voltage disconnect prevents excessively deep discharge that can permanently damage the battery.
