A nationally accepted electrical installation code to reduce the risk of fire, developed by the National Fire Protection Association.
Industry:Lights & lighting
A federal law enacted in 1988 that sets energy standards for ballasts consistent throughout the United States.
Industry:Lights & lighting
The standardised part number used by the US Government for procurement.
Industry:Lights & lighting
Laboratory that sets safety standards for building materials, electrical appliances and other products for Mexico.
Industry:Lights & lighting
Capacitor used in ballasts to help provide power factor correction. Contains no polychlorinated biphenyls and meets EPA requirements.
Industry:Lights & lighting
Ballasts with power factor less than .90 and do not incorporate any means of Power Factor Correction.
Industry:Lights & lighting
Open Circuit Voltage measured across the socket the lamp screws into, with the ballast powered on. It is dangerous to stick a voltmeter into such a socket without precise knowledge of the ballast because exceedingly high voltages could be present.
Industry:Lights & lighting
Lamps that are approved for burning in open fixtures (as opposed to enclosed fixtures which have an acrylic lens or plate glass enclosure).
Industry:Lights & lighting
Mercury and High Pressure Sodium lamps may be operated in any burn position and will still maintain their rated performance specifications. Metal Halide and Low Pressure Sodium lamps, however, are optimised for performance in specific burn positions, or may be restricted to certain burn positions for safety reasons. U = Universal burning position; HBU = Horizontal -15º to Base Up; HBD = Horizontal +15º to Base Down; HOR = Horizontal ±15º; H45 = Horizontal to -45º only; VBU = Vertical Base Up ±15º; VBD = Vertical Base Down ±15º. If no special burn position is noted, the burn position is universal.
Industry:Lights & lighting
For electrical discharge lamps, this is the voltage measured across the discharge when the lamp is operating. It is governed by the contents of the chamber and is somewhat independent of the ballast and other external factors.
