Understanding Lux and PPFD

Lux is a unit of illuminance that measures the amount of light falling on a surface. PPFD (Photosynthetic Photon Flux Density) measures the number of photosynthetically active photons (400-700 nm) falling on a surface per unit area per second. The conversion factor of 0.55 is used for a typical 4000K light source, but this can vary depending on the light source's spectrum.

Practical Applications

This calculator is useful for greenhouse growers, hydroponic enthusiasts, and plant researchers who need to ensure optimal light levels for plant growth. By converting Lux to PPFD, you can better understand the photosynthetic efficiency of your lighting systems.
