What is the color temperature, and how does it affect the light output?
A common misconception is the higher the k (Kelvin), the brighter the light. This is actually the opposite. The higher the color temp of the bulbs, the lower the actual light output. To put it into perspective, a 4300k bulb has a light output of 3200lm, while a 12000k bulb has a 2100lm output. Also, the higher the color temp, the more blue the light will be. For your reference, the color temperature of the sun is roughtly 4700k. Go to our COMPARE section to see temperatures in their true color.
