An attractive emergency lighting solution for harsh, vandal-prone environments, the SV16 employs MR16 lamps. The housing, back plate, and electronics shell are molded from high-impact polycarbonate and meet UL's flame-retardant standard for emergency lighting products. Appropriate for wet locations, the SV16 is fully gasketed to prevent water entry and functions in temperatures ranging from 5 to 104 degrees Fahrenheit-a capability achieved through the use of an optional battery heater.
