Light bulbs. How complicated can they be?
To be fair, sometimes they are. Along with other important life skills such as balancing a checkbook and jumpstarting a car, they don’t teach you how to change a light bulb in school. And when you check the stores for a replacement for your kitchen lights, you’ve got to choose between different types, different CRIs, lumen outputs, Energy-Star qualifications, and other specifications that leave you standing aimlessly in the aisles, Googling the difference between CFLs and LEDs in five minutes to make a decision.
Sometimes the descriptors or specifications written on light bulb packaging aren’t very intuitive. So let’s take it one at a time, starting with Kelvins.
Soft White – 2700 Kelvins
Cool White – 4100 Kelvins
Day Light – 6500 Kelvins
Soft White—also known as ‘warm white’ (2700K)—is a more traditional soft light. It most closely reproduces the color of an incandescent light bulb. As you go higher in color temperature (higher Kelvins, 6500K) the color is a bright bluish light.
