A Foot Candle/Lux Meter simply measures the intensity of light as perceived by the human eye. One lux is the equivalent of the amount of light by a full moon on a cloudless night, where direct sunlight is over 32,000 lux. One Foot-Candle, on the other hand, is about the same amount of light as is produced a foot away from a candle; two simple scales to measure the same thing-light intensity.

Light intensity is typically measured in office buildings, photography studios, schools, computer labs and anywhere that motion pictures are being recorded. Light intensity is very important for the proper development of pictures and film and it can even change people’s moods. Workers prefer a well-lit environment and work more efficiently if they aren’t straining their eyes to see a computer screen due to dim light.

This meter is especially accurate thanks to its ability to narrow down light based on how it is produced. With 4 different light settings to choose from it is easy to get a highly accurate reading. This instrument has a range up to 50,000lux (5,000Fc) to measure light intensity even in direct sunlight. This meter also has the ability to interface with a PC for downloading data.
