How it works
Light bulb color temperature, measured in kelvin, compares a light’s color with that of an ideal glowing object heated to that temperature. Lower numbers look warm and orange, like candlelight and old incandescent bulbs; higher numbers look cool and bluish, like daylight. The kelvin rating describes color only — brightness is measured in lumens.
