Illuminance

… indicates how much luminous flux hits a certain surface. The unit of measurement is lux (lx) . The formula for illuminance is: Luminous intensity in candela (cd) divided by the distance2 (/ Radius2) between the light source and the surface.

Kelvin

... is the unit of color temperature and describes the color of a light source. (see also CCT and color temperature). Comfortable light has 2000 to 3300 Kelvin, cold, radiant light like in large warehouses has over 5300 Kelvin. LEDs, for example, can cover the entire span.

LED

… stands for light-emitting diode and denotes an electronic semiconductor component which emits light when a current flows through it. Leds are very economical in comparison to conventional incandescent lamps, have a significantly longer service life and can reproduce a wide range of color temperatures..
