OSHA - Occupational Safety & Health Administration
EPA - Environmental Protection Agency
NFPA - National Fire Protection Association
ASHRAE - American Society of Heating, Refrigeration and Air Conditioning Engineers
EEMs - Energy Efficiency Measures
What are the 3 types of metering schemes? - Master Metered, Direct Metered, Sub-
Metered
IESNA - Illuminating Engineering Society of North America
Lamp - A generic term for a source created to produce optical radiation.
Lumens - Technically "luminous flux". The amount of light that a bulb produces. It is a
unit of output.
Initial Lumens - Lumens measured before depreciation occurs.
Mean Lumens - The lumen output that lamp is statistically likely to output at 40% of the
lamps rated life.
Foot Candles - Units of light density striking a surface. One footcandle is defined as one
lumen distributed uniformly over one square foot.
Efficacy - The efficiency of the lamp, expressed in Lumens per watt (LPW). It is the ratio
of the total light (lumen) output over the total energy (watt) input.
CCT - Correlated Color Temperature
CRI - Color Rendering Index
Ballast - A device used with a discharge lamp to provide the necessary circuit conditions
(voltage, current, and waveform) to start and operate the lamp.
Luminaires - A complete lighting unit consisting of: lamps, ballast (if applicable), as well
as parts designed to: distribute light, position the lamp, protect the lamp, and connect
the lamp to the power supply.
