Obviously standard light metres can do this math for you, But Im seeking to better understand this math. Lux to lumens conversion. In order to convert lux to lumens or lumens to lux, the correlation between the two quantities must be found. Since it is the emitted light on the one hand and the received light on the other hand, other factors also play a role. Therefore, 100 lux or less is generally termed as indirect or low-intensity lighting. Usually, a bright office has roughly 400 lux of illumination. Also, bright indirect light is about 800-2000 foot candles and differs based on the position of the plant.

Belysningsstyrka – Lux (lx) anger hur mycket ljus som faller in på en belyst yta. Vi får en av A Liljemark · 1958 — och 50 foot-candles (1 f.c. = 10,8 lux) än mellan 50 och 75 resp. 100 f.c. från lysrör.

How to convert foot-candles to lux. We all use different units of measurement every day. Whether you're in a foreign country and need to convert the local imperial units to metric, or you're baking a cake and need to convert to a unit you are more familiar with. A foot-candle is defined as the amount of light that falls on a surface that is one foot away from a single candle. Light intensity can also be measured in Lux (1 foot-candle = 10.764 lux).

1 lux to footcandles = 0.0929 footcandles.

Full Sun – (40,000–130,000 lux; 5000 foot candles+). Green filter: 205 foot-candles; 30 μmol/(m²⋅s) Blue filter: 205 foot-candles; 27 μmol/(m²⋅s) Interpretation: when you normalize for perceived brightness (foot-candles), the red light was the only color to show a discrepancy – that the lux/fc meter was not very sensitive to red light. One foot-candle equals 10.76 lumens (a lumen is considered the same as lux, which is what most modern light meters calculate their measurements in), so in order to convert your foot-candles to lumens, you will need to take the amount of foot-candles measured and multiply by 10.76 to get the number of lumens. 1 Nit equals 0.092903 Foot-candle.
