Lamp Voltage: The voltage at which lamps operate when they are fully warmed up Lamp Wattage: The power consumed by a lamp after warm-up Light Center Length (LCL): The distance from the center of the arc discharge to the end contact of the base Lumens: A measurement of light output; takes into account the human eye sensitivity curve so that more weight is given to the yellow-green part of the light spectrum Lumen Maintenance: The lumen output provided by a lamp at a given point in or percentage of its life Lumens Per Watt (LPW): A ratio of lumens to watts; often calculated with either lamp watts or system watts; measured in lumens per watt (LPW) Luminaire Requirements: The type of luminaire a lamp requires; i.e., enclosed or open rated Maximum Overall Length (MOL): The maximum allowable distance from the top of the glass bulb to the end contact of the base Normal (Low) Power Factor Ballast: A ballast of the multiple-supply type that does not have a means for correcting the input power factor Occupancy Sensor: Control device that dims or turns lights off after the space becomes unoccupied; may be ultrasonic or infrared-actuated Open Circuit Current (Line): The RMS current measured through the input terminals of a ballast with lamp removed or inoperative Open Circuit Voltage, Ballast (OCV): The voltage across the output terminals of a ballast when no load is connected (RMS, unless otherwise stated) Open Rated Lamp (E27): Designed for open luminaires; has a narrower neck than standard E27 base lamps. Lamp arc tube is surrounded by a protective quartz shroud. Open Rated Lamp (E40): Designed for open luminaires. Lamp arc tube is surrounded by a protective quartz shroud. Operating Current (Line): The power factor corrected current measured through the input terminals of a ballast which is operating a reference lamp Operating Voltage: The voltage at which lamps operate when they are fully warmed up Peak Lead Ballast: A ballast that produces a highly peaked open circuit voltage wave shape and has a capacitor in series with the lamp Position Oriented Mogul Base (POMB, EP39, EP40): Used with horizontal burning lamps; has an aligning pin embedded in the base for proper lamp orientation when it is screwed into its socket; should only be used in yellow Glossary cont.
