Color Temperature,Color Rendering Index and Reflection Factor
What is color temperature? The color temperature of a lamp determines whether the light gives a warm or cool impression. The color temperature is given in Kelvin and can be assessed on a scale. The lower the color temperature, the warmer and darker the light appears. The higher the color temperat...Read more -
How are lumen, candela and lux related?
The terms lumen, candela and lux occur very frequently in light measurement. They are all photometric quantities. The following diagram shows the relationship between the three terms. The unit lumen stands for the total light output of a luminaire emitted in all directions. However, since the li...Read more -
What is lux?
Lux provides information about the illuminance. It is a measure of the brightness with which an area is illuminated. Lux indicates how much luminous flux (lumen) of a light source arrives per unit area of a receiver surface. The value lux is purely a receiver quantity. Illuminance is calculated w...Read more -
How to measure light intensity?
Luminous intensity is an important value for comparing different lamps. Lamps with the same luminous flux can have completely different luminous intensities due to their beam angle. The beam angle indicates the angle at which the light is emitted by the lamp. The luminous intensity or its candela...Read more -
Introduction of luminous efficiency and light intensity
The luminous efficiency is a measure that indicates how efficient a light source is. It is the ratio of lumens to power or watts, so it is measured in lumen per watt (lm/W) in the International System of Units. The higher the value, the more efficient a light source is. Exemplary lumen val...Read more -
Introduction of Light and the Light Flux
What is light Light consists of photons, also called light particles. They travel in waves and transmit energy impulses. Light is created when energy is converted. When visible light is emitted, this is also called luminescence. How bright and colorful the human eye can perceive a light depends o...Read more -
