    • Kelvin Temperature of a Light Bulb

    Kelvin is the “color temperature” of the light bulb.

    Kelvin scale comparative values of light sources.

    Here is a list gives you an idea of where some light sources are relative to one another on the Kelvin scale.

  • Candlelight = 1,850K
  • High Pressure Sodium = 2,000K
  • Regular Incandescent Bulb = 2,750K
  • Warm Fluorescent Bulb = 3,000K
  • Some Halogen Bulbs = 3,000K
  • Mid Range Fluorescent Bulbs = 3,500K
  • Cool Fluorescent Bulb = 4,100K
  • Some Metal Halide Bulbs = 4,500K
  • Special Fluorescent Bulbs = 5,000-6,300K
