What is Light Measurement? Understanding Lux And Foot-Candle

Proper lighting isn't just about aesthetics—it's essential for productivity, safety, comfort, and even energy efficiency. Whether you're setting up an office, checking indoor plant conditions, or inspecting a workspace, knowing how to measure light accurately is crucial.

What is Light Measurement?

Light measurement refers to the process of quantifying the intensity of visible light in a particular area. This is especially important for:

  • Interior design and architecture
  • Workplace safety compliance
  • Photography and cinematography
  • Agriculture and plant growth
  • Industrial inspections

Units of Measurement: Lux vs. Foot-Candle

Lux (lx)

Lux is the metric unit of illuminance.
It measures how much light hits a surface.

  • 1 lux = 1 lumen per square meter

Common lux values:

  • 50 lux – hallway lighting
  • 300–500 lux – office or classroom
  • 1000+ lux – surgical or laboratory work

Foot-Candle (fc)

Foot-candle is the imperial unit of illuminance.

  • 1 foot-candle = 1 lumen per square foot
  • 1 foot-candle ≈ 10.764 lux

Some industries in the U.S. still use foot-candles, especially in construction, film, and OSHA standards.
