New York Approved Ballasts & Drivers
Ballasts & Drivers
An electrical ballast or driver is a device intended to limit the amount of current in an electric circuit.
A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.
Emergency Lighting is now selling programable LED drivers that will allow your LED lighting to be dimmable. When your driver goes out let us know the milliamps of the driver and we can program the LED to the exact milliamps.
New York Approved
New York City requires that any exit signs and emergency lights:
- Meets New York City Electrical Code (meets UL certification)
- NFPA & OSHA require initial illumination of 1 foot-candle and a minimum at any point of 0.1 foot-candle. New York City emergency lighting requires TWICE that (an average of 2 foot-candle or 22 lux and a minimum at any point of 0.2 foot-candle or 2.15 lux measured along the path of egress at floor level). This is why The Exit Light Company recommend emergency lights with nine (9) watts on each head. Since even with the requirement for brighter lighting, the minimum standard of 90 minutes of run-time on battery backup power is in effect, NYC Code approved emergency lights are heavy-duty units with larger batteries.
- The letters of exit signs and exit sign/emergency light combos are mandated to be red.
- The height of letters shall be not less than 6 inches (152 mm), except that in Group A (theaters and concert halls) and Group R-1 (Shelters, Fraternity & Sorority Houses) occupancies letters shall be not less than 8 inches (203 mm) high. A change from previous years, now U.S. standard 6" exit signs are acceptable in most locations, but certain locales still require 8" exit signs.
- All signs shall be of metal or other durable materials.
- All high-rise buildings require photoluminescent exit path markings for egress routes.
