Lumens will provide the overall brightness of the image, while lux will determine how clearly the image is visible. When it comes to projectors, both lumens and lux should be taken into consideration. Generally speaking, the higher the lux, the clearer and brighter the image will be. Lux is important to consider when projecting onto a screen, as it will determine how much of the image is visible. The other factor to consider is lux, which is the measure of brightness per square meter. However, the brightness can also depend on the size of the projector and the environment in which it is used, with larger projectors and darker rooms requiring more lumens. The higher the lumens, the brighter the image will be. Lumens refer to the amount of light projected from the projector, which is measured in lumens per square foot. While both are important factors to consider when choosing a projector, each has its own unique benefits and drawbacks. The comparison of ANSI Lumens vs Lumens will also help you make better informed brightness decisions.When it comes to projectors, there is often a debate over which is better: lux vs lumens. So when trying to compare the brightness of two light sources, you must consider all relevant factors to ensure an accurate comparison. However, you must remember that perceived brightness is not entirely defined by a value but dependent on other determining factors, such as the size of a projected screen and its distance from the source, the viewing conditions, ambient lighting levels, and most importantly contrast.īrightness is a subjective measurement of how bright or dark something appears, and although we use it as a description of luminance, ‘brightness’ does not produce luminance, merely how we perceive it. So in terms of choosing displays, TVs and projectors, the difference between light output and ‘brightness’ or the luminance of a screen, can be calculated and compared. 2000 lumens of projected light = 613 nits of screen luminance.400 nits brightness of a screen is equivalent to 1370 lumens from a projector. ![]() * dividing 3.426 into the LED Lumens to convert to Nits Comparing BrightnessĬomparing lumens to nits is ultimately a brightness comparison so you can understand which value will be visibly brighter.įor example, when comparing the brightness of a projector to a TV or display: Lumens vs Nits Conversion Table LED Lumen Therefore, 1 Nit is perceived as brighter than 1 Lumen. The ratio for the difference between Nits and Lumens is: Lumens to Nits ConversionĪlthough Nits and lumens are two different units of measurement, there is a way to convert between the two to assist in a comparison between different sources, such as comparing the brightness of a projector with a TV or display screen. In terms of displays, lumens measure a projector’s output and nits measure the screen’s brightness. Lumens or ANSI lumens are used as a measurement of how much light is being projected whereas the Nit unit defines the luminance or brightness of an object.īoth are used to quantify optical output but Lumens are a unit of light created, whereas Nits are a unit of measurement for how much visible light is being seen. ![]() What is the Difference Between Lumens vs Nits The higher the nit rating, the brighter your screen will appear. Nits are important because they directly affect the perceived brightness of a screen. The brightness of a digital display or screen and how it appears to the human eye are often quantified in nits. The unit of a NIT is derived from the latin word ‘ nitere‘, meaning ‘to shine’. ![]() The nit is a unit of measurement that quantifies the luminance of an object or how much visible light an object emits and is being seen.ġ nit is equal to 1 candela per square meter (cd/m2). The brighter you need your image to be, the higher its lumen rating should be. Lumens are a unit of measurement that directly affect the brightness of your projector or screen. The ANSI Lumen rating is the most common measure of brightness used by projectors, and it’s generally considered to be the most accurate method to compare different projector models.
