How many Lux equal a foot-candle?
10 lux
Thus a foot-candle is equivalent to approximately 10 lux or 10.57 lux. A higher number of lumens are indicative of a brighter, more intense light, whereas a lower number of lumens represent dimmer, more subdued lighting.
How many foot candles is 1000 lumens?
A lumen is a way of measuring how much light gets to what you want to light. To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens.
What are 1000 foot candles?
Full daylight typically equals about 1,000 foot-candles, while an overcast day would have only 100 foot-candles of light. Twilight produces just 1 foot-candle, while a night with a full moon has 0.01 foot-candle and an overcast night has only 0.00001 foot-candle.
How do you calculate lux?
One lux is equal to one lumen per square meter (lux = lumens/m2). Essentially, as light travels from the emitter, it will disperse throughout an area. The further the light has to travel the more it will be dispersed.
What is the difference between foot-candles and lux?
Foot-candles and lux measure the same thing—the amount of visible light that falls on a surface. The difference is that the foot-candle uses the Imperial standard measuring system (feet, pounds, etc.), while the lux uses the metric system (meters, grams, etc.). For conversion, 1 foot-candle = 10.764 lux.
What does lux mean in lighting?
illuminance
Lux is a standardised unit of measurement of light level intensity, which is commonly referred to as “illuminance” or “illumination”. 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.
How do you convert Lux to foot candles?
A foot-candle equals 1 lumen per square foot. The international standard (SI) counterpart of the foot-candle is the “lux.”. A lux equals 1 lumen per square meter. The equation used to convert foot-candles to lux is: 1 foot-candle = 10.76 lux.
