Choosing the correct color temperature: Understanding Kelvin temperature (K) makes it easier to choose lighting that gives you the look and feel you want.

Kelvin temperature is a way to describe the light appearance provided by a light bulb. It is measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. Typically, Kelvin temperatures for commercial and residential lighting applications fall somewhere on a scale from 2000K to 6500K with 2000K being the yellowest spectrum and 6500K being the bluest spectrum. The lower the kelvin temperature is the more yellowish glow it will give and the higher the kelvin temperature the bluer shine it will give out.

Light bulbs are typically divided in 3 color categories Warm White (3000K), Cool White (4100K) and Daylight (6500K). The KOR K25698 is a 6500K Bright White / Daylight color. Please make sure to choose the color option that works for your application.
