Life span:Conventional "bulbs" have a life of 1000 hours. The new LED high-power lamps ielli live up to 50,000 hours.

Kelvin:Kelvin: The Kelvin [K] is used not only on the temperature information on thermometers, but also serves as a measure of the color temperature of light. A burning candle has approximately 1,500 K, a traditional light bulb 3,000 K and 6,500 K the sunlight. The lower the value, the "warmer" the light appears. High Power lamps were deliberately modeled after the bulbs and appear therefore warm white.

Light and color rendering:To describe the color rendering of light sources, the so-called color rendering index (CRI abbreviation) was developed. He is based in principle on the measurement of light at defined wavelengths or colors (pastel colors). Although not all of the light spectrum is taken into account because it gives a good indication of the quality of light.
Traditional light bulbs have, by definition, the value of CRI = 100. Lamps with a color index greater than 80 indicate already good quality of light.

High-power lamps…have value of more than CRI 80. By the way incandescent and halogen lamps produce very little blue light, which is why it is sometimes difficult to distinguish blue and black. This was taken into account in our LED lamps and corrected accordingly.

Luminous flux:This value is the amount of light, irrespective of the direction of radiation and is measured in lumens [lm]. The luminous flux of a 40W incandescent lamp is around 330 lm and is almost radiated in all directions from the lamp. But a very large portion of the light is mostly lost in the lightsource or in shade. Critical to the brightness of a lamp is therefore more likely to use and the resulting illumination.

Illuminance:Illuminance is the luminous flux, falling on a given surface. This is measured in lux [lx] and is calculated as lumen per square meter [lm/m2]. A high-power LED lamp with 7 W achieved in a hanging lamp, even a higher range than a 60 W incandescent lamp.

Brightness:The intensity describes the part of the luminous flux emitted in a certain direction. The light intensity is therefore largely determined by light-directing elements. A typical example is the "lamp shade" of a light by which can radiate the light of the lamp only screwed down. The unit of luminous intensity candela [cd] (candle) is. An ordinary candle has a luminous intensity of 1 cd, reached a 100-watt light bulb 1,100 cd.
