What color temperatures are available with LED bulbs?

Color temperature for light bulbs is measured on the Kelvin scale. LED Bulbs come in a variety of colors, but the most common is in a range from 2700K to 7500K. The unfortunate thing is that the only consistent measurement is the Kelvin scale, Many manufacturers like to use terms like Day White, Natural White, Warm White and Cool White, but there is not a standard that defines a Kelvin temperature to associate with those terms. The general rule is WARM (2700K) to COOL(6500K+). The warmer the light, the more yellow tones, the cooler the light, there are more blue tones.

Here are the typical ranges of color temperatures in My LED Lighting Guide:

* 2700-3200 – WW – Warm White
* 4000-4500 – NW – Natural White
* 5000-5500 – DW – Day White
* 6500-7500 – CW – Cool White
