 - the American National Standards Institute, Inc is the coordinator of including lighting standards on a national level.


Arc Lamp - a discharge lamp in which the light is emitted by an arc tube.


Arc Tube - a tube made of clear quartz or ceramic material within a glass envelope of an HID lamp that contains the arc stream.


Ballast - a device used to create a starting voltage and stabilize electrical current for fluorescent lamps and HID lamps.


Base - the part of the lamp that connects to the socket.


Beam Candlepower - measure of beam intensity reflected from a reflector lamp.


Beam Spread - the angle of light distributed from a reflector lamp.


Color Rendering Index (CRI) - a rating for fluorescent lamp to examine its variance from outdoor natural light which has a defined CRI of 100. The rated ability of an artificial light source to render an objects true color.


Foot Candle - a unit of illumination. Equivalent of one candle emitting light on one square foot of surface area from one foot away.


Halogen - a tungsten incandescent filament lamp with a quartz envelope containing a proportion of halogen inert gas.


Kelvin Temperature Scale - a measurement of color appearance in degrees Kelvin (K).


Krypton -a heavier inert gas used in a variety of lamps to produce a brighter white light as well as longer lifetime by reducing the rate of filament decay.


Lumen - a measure of luminous flux. The quantity of light emitted by an artificial light source.


MOL - Maximum Overall Length. Length from the tip of the glass envelope to end of the base.


Nominal Length - overall length of a fluorescent lamp including sockets.  Generally, this measurement is from the back of one socket to the back of the opposing socket.


Watt - a unit of power consumption.
