About Light & Illuminance Conversions

Illuminance conversions between lux, foot-candles, and phots are used in photography, interior design, workplace safety standards, and agricultural lighting. Luminance conversions help display engineers and lighting designers work across different measurement systems.

Luminous flux (lumens) and luminous intensity (candela) conversions are important when comparing light bulbs, projectors, and LED specifications. These units help you understand both the total light output and the directional brightness of light sources.
