3. CANDELA : It is equalent to the illumination of one standard candle.
FOOT CANDELA : It is the amount of illumination on a surface from a light source of on candela that is a foot away from the surface.
ONE FOOT CANDELA =1 Lumen /Square foot.
ONELUX:ItIstheamountofilluminationcreatedbyalightsourceofonecandelawhichisonemeterawayfromthesurface.
1LUX=1Lumen/Squaremeter.

9. COLOR RENDERING INDEX (CRI)
The color rendering index (CRI), sometimes called color rendition index, is a quantitative measureof the ability of a light source to reproduce the colors of various objects faithfully
in comparison with an ideal or natural light source.
Color rendering: Effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant.
Finishes should be evaluated under the type of lamp (lamp and/or daylight) which will actually be used in interiors.
Color rendition depends on lamp color spectrum, reflective property of surfaces and context and condition in room.
Judgment of apparent surface color depends also on the experience of expectations of an individual with normal color vision.

How does Color Temperature affect the appearance of a room?
Warm light
Cool light
Daylight light

11. LIGHTING FIXTURES
Light fixtures is integral part of building electrical System, transforming energy into usable Illumination.
Light fixtures requires: electrical connection (power supply), lamp holder, lamp (design to diffuse, Reflect, focus light).
Form of lighting fixture, lighting sources, light Illumination:point sources, linear sources, planar sources, volumetric sources.

12. LIGHTING LUMINARIE
An assembly used to house one more light sources.
Also calledlighting fixture.

33. INCANDESCENT LAMP
WHAT?
HOTWIRE –FILAMENT SEALED IN A GLASS JAR (BULB)
HOW?
ELECTRIC CURRENT PASS THROUGH THE WIRE HEATS IT TO INCADESCENCE, AND THE WIRE EMITS LIGHT . USE STANDARD VOLTAGE CIRCUIT

34. INCANDESCENT LAMP
Inside the glass is a gas such as argon and/or nitrogen. At the center of the lamp is a tungsten
Filament up to about 2,500 degrees Celsius. Just like any hot metal, the tungsten gets “white hot” at that heat and emits a great deal of visible light in a process
