electrical level 3 mod 3
The international system (SI) unit of luminous intensity. It is roughly equal to 12.57 lumens. -
ANScandela
The measure of light intensity measured in candelas. Used to indicate the intensity of a light
source in a given direction. - ANScandlepower
The unit used to measure how much total light is reaching a surface, such as a wall or table is
called - ANSfootcandle
Lighting on a work surface or object that is not predominantly incident from any particular
direction - ANSdiffused lighting
The parts of lighting fixtures that redirect or scatter the light produced by the fixture or lamp -
ANSdiffusers
The distance above the floor where the task is to be performed is called the - ANSwork plane
The basic unit measure of the amount of light produced by a light source is called a - ANSlumen
A candela is equal to ______ lumens - ANS12.57
Spreads a strong task light over work surfaces also used for lighting stairways and entrees. -
ANSopen downlight
Throws light onto a nearby wall. A series of fixtures can produce balanced light for artwork and
bookcases - ANSrecessed downlight
Those that use MR-16 tungsten halogen lamps and back baffles are widely used for accent
lighting... - ANSlow voltage downlights
Typically 2,3,4 lamp fixture. 2'and 4'. generally used where low mounted task lighting is needed.
Work stations, storage areas and utility rooms - ANStask area fluorescent fixtures
Entrance elevator, escalator lobbies, corridors and stairways. usually lighted continuous or for
long periods of time. usually ceiling and wall mounted fixtures - ANSpublic areas
Corridor lighting levels should provide at least______ of the luminance of adjacent areas -
ANS20%
