Lumen is the international unit of lumonous flux, a measure of overall light emitted by a light source.
2. Candela (cd)
Candela is the international(sl) unit of luminuous intensity,a measure of light emitted by a light souce in a particular direction. Any given light source will have different luminous intensities in different direction considered. [candela = lumen/solid angle]
3. Beam Angle [Unit: degree]
Beam angle is the angle betweent two directions for which the luminous intensity is 50% of the maximum intensity as measured in a plan through the nominal beam centerline.Beam angle of a lamp give an idea of how the light beam spread away form the beam center.
4. LUX (lx)
Lux is the international(SL)unit of illuminance, a measure of light arriving at a surface, 1 lumen per square foot equals 1 footcandle, while 1 lumen per square meter equals 1 lux .[lux = lumen/m2]
5. Color Temperature / Correlated Color Temperature (CCT)
A black-Body radiator will have different color whent it is heated up to different temperature(in kevin). The Temperature at which the heated black-body radiator matches the color of the light source is the color temperature of the light source.
6. Color Rendering Index (CRI)In easy terms CRI is the quality of light and is represented by a number from 1 (worse) to 100 (best). A CRI of 100 means the light has the same quality as sunlight, it is pleasant and all colors look natural. At CRI of 60 the light has an unpleasant feel and colors look unnatural (for example Skin appears less pink, and hence “unhealthy”)
A: Because LEDcan nowachieve the necessary light output levels to compete with other sources such as halogen and fluorescent, as well as being much easier to install, and eminently more versatile in their areas of use,
LED’s are now the most discerning option for both domestic and business users.
Apart from offering a very bright, cool running, controlled instant light, LED products can last up to 15 times longer than conventional light sources; use on average 80% less energy to create comparable light levels,
which directly translates into considerable reductions in utility bills, as well as contributing to a sizeable reduction in CO2 emissions.
