Flood (Light): describes light cast in a confided manned over a broad area as a result of interaction with optics and reflectors.
Fluorescent Lamp: A light source technology that relies on the excitement of
phosphors to convert a limited spectrum of radiation into a more complete spectrum of visible light Foot-Candle (FC): The (English) unit of
expressing and measuring light flux onto an object, where 1 Foot-candle is the equivalent of one lumen of light arriving evenly onto a surface area of 1 square foot.
G
Glare: Excessive brightness created by an unshielded light source. Also describes the reflection of bright objects visible in a specular surface Grazing: The tactic of lighting a surface at a severe angle from a nearby light source. Tends to spread light over a great distance and reveal texture H
Halogen lamp: A light source technology that relies on an incandescing
filament within a pressurized environment of halogen gas.
High Intensity Discharge (HID) Lamp: A light source technology that relies on an arc of electricity passed between electrodes to excite an environment of vaporized metal. Includes sources such as Mercury Vapor, High Pressure Sodium and Metal Halide.
I
Illuminance: An expression of light quantity incident onto a surface. Expressed and measured in Foot-candles (FC) (English unit) or Lux (LX) (SI unit).
In-grade (Luminaire): (See direct burial)
Incandescent lamp: A light source technology that relies on radiant energy emitted from a metal filament resisting a flow of electricity.
Indirect Light: light distributed after it reflects or interacts with a shielding
surface
Inter-reflection: The product of light interacting with the objects and surfaces of a space.
L
Lamp: The generic term for an engineered light source
Lamp Life: An expression of the expected operating life of a light source expressed in hours.
