Lux is a standardised unit of measurement of light level intensity, which is commonly referred to as “illuminance” or “illumination”. So what is exactly 1 lux? A measurement of 1 lux is equal to the illumination of a one metre square surface that is one metre away from a single candle.
What lux means?
lux, unit of illumination (see luminous intensity) in the International System of Units (SI). One lux (Latin for “light”) is the amount of illumination provided when one lumen is evenly distributed over an area of one square metre.
Is lux the same as lumens?
Lux is used to measure the amount of light output in a given area – one lux is equal to one lumen per square meter. It enables us to measure the total “amount” of visible light present and the intensity of the illumination on a surface. Thus, it is important in what direction the light source shines.
How many lumens is a lux?
1 lux equals 1 Lumen/m2, in other words – light intensity in a specific area. Lux is used to measure the amount of light output in a given area. One lux is equal to one lumen per square meter. It enables us to measure the total “amount” of visible light present and the intensity of the illumination on a surface.
How many lux is the sun?
In the real world, sunlight delivers about 120,000 lux. Set the brightness of the sun in your game to 120,000 lux, and voila — your sunlight matches reality. Candela and lumen ratings for real lights are freely available.
How do I check my lux level?
