What Is Color Temperature?

Color temperature is measured in Kelvin (K) and describes the hue of white light. Despite the name, lower Kelvin values produce warmer (yellow/orange) light, while higher values produce cooler (blue-white) light — counter-intuitive, but consistent with blackbody radiation physics.

Warm light (2700–3000K) creates a cozy, relaxed atmosphere and is flattering for skin tones, making it the most popular choice for residential spaces. Neutral light (3500–4000K) feels crisp and clean, ideal for tasks requiring focus. Cool daylight (5000K+) mimics natural daylight and maximizes alertness and visual acuity.

The color temperature of a bulb does not affect its brightness (lumens) or efficiency (watts). You can have a very bright warm bulb or a very dim cool bulb — they are independent properties. When choosing lighting, match color temperature to the mood and function of the space.
