About Lux & Lumens

Understanding lighting terminology:

  • Lux (lx): Unit of illuminance, measuring light intensity on a surface
  • Lumen (lm): Unit of luminous flux, measuring total light output
  • 1 lux = 1 lumen per square meter
  • For a specific illuminance, Required Lumens = Area × Target Lux

Fixture Guidelines

Typical lumen outputs by fixture type:

  • LED Bulb (60W equivalent): 800-900 lm
  • CFL (15W): 800-1100 lm
  • Incandescent (60W): 650-800 lm
  • LED Strip (per meter): 400-600 lm
  • T8 Fluorescent (4ft): 2500-3000 lm

Usage Tips

  • Consider layering different light sources for better ambiance
  • For task lighting, increase lux levels in specific work areas
  • Account for wall reflectance - dark walls absorb more light
  • Higher ceilings may require more powerful fixtures or more fixtures
