Color Temperature

Infrared (Invisible) <- - RED - Lowest Color Temperature & Highest Color Temperature - BLUE --> Ultraviolet (Invisible)

1,500 K - Candlelight or Fireplace

Circadian for human dating back to time to use fire lighting for winding down the day for bedtime. Before the invention of electricity and backward was how long human had evolved with fire.

2,680 K - 40 W Incandescent Lamp - LED has now achieved to as low as 2200 K

Night leisure reading and light evening activities.

3,000 K - 200 W Incandescent Lamp or a typical IKEA LED light bulb now

For late night workers

3,000 K - 3,200 K Halogen

Light spectrum that project crisp definition of surrounding objects effectively. Tungsten Halogen is pretty easy to determine a color temperature on since it uses a glowing filament. Tungsten has a maximum temperature it can burn at that balances brightness, efficiency and bulb life. So an uncoated bulb will be somewhere between 3000–3200K.

3,200 K - Sunrise/Sunset

The ambiance of dawn and dusk that is best for any artificial lighting used for the early morning and evening.

3,400 K - Early afternoon before sunset

Transition from the intensity of noon time light

3,700 K - Above Halogen range and not as intense as the bright sun at noon

Light just above the Halogen range sufficient for indoor sport activities within condominium or the home after the workday

5,000 K - 4,500 K - Xenon Lamp/Light Arc

Xenon lamp / light arc

5,500 K - Sunny daylight at noon

Sunny daylight around noon, eye pupils squint to smallest

5,500 K - 5,600 K - Electronic photo flash

Electronic photo flash when using flash camera

6,500 K - 7,500 K - Overcast sky

Overcast sky that contains diffusing water particles that lowers the color temperature sometimes by a over 5,000 Kevin

9.000 K - 12,000 K - Blue sky

Blue sky light intensity is also contributed by the clear air without particles that diffuse the light, as compared with light under sky overcast by cloud (water particles).
