Lux is the globally standardized SI unit of illumination. It provides a uniform standard by which the amount of visible light present in a given space can be described. A lux rating is used to describe the perceived illumination of a known space, such as
The lumen is presently the standard against which the candela, the unit of light intensity, is measured. The power of a point source of monochromatic light with a 555 nm wavelength and a luminous flux of 1 cd/m2 equals one candela. What are the relationships between Candela, Lux, and ...

Use that amount and divide it by the result on your digital lux meter, and you should get the estimated number of nits your device's display contains. What is the Ideal Nits Brightness? Now that you're past the technicalities of a nit and know what it is, it's time for this ...
DLP is a technology from Texas Instruments (TI) that uses a single chip with many tiny mirrors to reflect different color segments from a color wheel very precisely in one second. Thus, its colors may not be as vibrant as those produced by three-color LCD technology, which is why some pe...
If you have no idea how to compare a projector's brightness output to a TV or any other emissive display, fret not; we were in the same boat when we started developing our projector test bench. What's a lumen anyway, and more importantly, how many nits (cd/m²) is it?
ANSI lumens = average of Lux readings X image area in square meters Why Measure Lumens in Different Color Modes? Most projector spec sheets, and even many reviews, give a single value for ANSI lumens, stating the projector's highest brightness level. Although this tells you the maximum illumin...
Amount of light is measured in lumens & Lux. Lumen is intensity of light, while Lux = light amount per square meter. Almost all of the lighting products mention lumens in their description. So you need to decide how much lumens you require. ...
Afoot-candleis a measurement of light intensity. One foot-candle is defined as enough light to saturate a one-foot square with one lumen of light. Lumensmeasure the total quantity of visible light emitted by a source. However, this measure doesn’t consider the wavelengths of light and theref...
Its unit is the lumen (lm). There are tables that indicate what the proper amount of lumens per square meter is for each environment. Generally this amount is given in lux (lx), which corresponds to a unit of luminance or illuminance, or the lumen of a surface for each square meter....
