Color temperature choices: We sought a bulb line with a range of color temperatures. Color temperature is measured in kelvin, and cooler light has a higher value, ranging from 3,600 to 5,500 K, while warmer light ranges from 2,700 to 3,500 K. Most brands describe 2,700 K temperatures as “soft white,” 3,500 K as “bright white,” and 5,000 K as “daylight,” with some in-betweens. People may prefer cooler light for bathrooms, kitchens, workspaces, and garages, and they may prefer warmer light for bedrooms and sitting areas.
