LED Color Temperature (Kelvin)
Understand the visual impact of your lighting choices. This reference guide explains the Kelvin (K) scale, helping you choose the right LED color temperature—from the warm, amber tones of a candle to the crisp, blue-white light of high-noon daylight.
| Color Name | Kelvin Range | Mood/Application |
|---|---|---|
| Warm White | 2700K – 3000K | Cozy, Residential |
| Neutral White | 4000K – 4500K | Office, Workspace |
| Cool White | 5000K – 6500K | Daylight, Laboratory |
Circadian Impact: Lower Kelvin temperatures (Warm White) are better for evening use as they contain less blue light, while higher temperatures (Cool White) are ideal for task-oriented workspaces.
CRI vs. Kelvin: Remember that Color Temperature is different from Color Rendering Index (CRI). Kelvin defines the color of the light, while CRI defines how accurately it renders the colors of objects.
