Frequently Asked Questions

How do I convert lux to foot-candles?

Multiply lux by 0.0929 (or divide by 10.764). For example, 100 lx = 9.29 fc. Foot-candles are commonly used in the US, while lux is the international standard.

What is a good illuminance level?

General office work requires 300-500 lux, reading needs 500-1000 lux, and detailed work needs 1000-2000 lux. Outdoor daylight is 10,000-100,000 lux.

What's the difference between illuminance and luminance?

Illuminance (lux) measures light falling on a surface, while luminance (cd/m²) measures light emitted or reflected. Use illuminance for lighting design, luminance for displays.

How many foot-candles in a lux?

1 lux = 0.0929 foot-candles. Conversely, 1 foot-candle = 10.764 lux. This conversion is essential for US building codes and lighting standards.

What illuminance is needed for photography?

Photography typically requires 100-1000 lux depending on ISO settings. Studio lighting often provides 500-2000 lux for controlled conditions.
