What are the 3 types of metering schemes? - correct answer ✔Master
Metered, Direct Metered, Sub-Metered
IESNA - correct answer ✔Illuminating Engineering Society of North America
Lamp - correct answer ✔A generic term for a source created to produce
optical radiation.
Lumens - correct answer ✔Technically "luminous flux". The amount of light
that a bulb produces. It is a unit of output.
Initial Lumens - correct answer ✔Lumens measured before depreciation
occurs.
, Mean Lumens - correct answer ✔The lumen output that lamp is statistically
likely to output at 40% of the lamps rated life.
Foot Candles - correct answer ✔Units of light density striking a surface. One
footcandle is defined as one lumen distributed uniformly over one square foot.
Efficacy - correct answer ✔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 - correct answer ✔Correlated Color Temperature
CRI - correct answer ✔Color Rendering Index
Ballast - correct answer ✔A device used with a discharge lamp to provide
the necessary circuit conditions (voltage, current, and waveform) to start and
operate the lamp.
Luminaires - correct answer ✔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.
Luminaire Efficiency - correct answer ✔The ratio of luminous flux emitted by
a luminair over that emitted by the lamp (or lamps) contained in the fixture.

correct answer ✔The number following the T indicates the diameter in 1/8ths
of an inch.
