LED Color Temperatures and Visual Examples

Incandescent bulbs typically emit warm yellow light (~2700 K). Modern LEDs offer multiple color temperatures that mimic or improve upon this warmth depending on the setting. Different color temperatures give LEDs their distinctive appearance—from warm candlelight to daylight white. The following images show real visual approximations of each temperature.

2200 Kelvin - Warm candlelight — 2200 K – Very Warm (Candlelight)

2700 Kelvin - Warm white — 2700 K – Warm White (Home Lighting)

3000 Kelvin - Soft white — 3000 K – Soft White

3500 Kelvin - Neutral white — 3500 K – Neutral White

4000 Kelvin - Cool white — 4000 K – Cool White

5000 Kelvin - Daylight white — 5000 K – Daylight White

5600 Kelvin - Daylight — 5600 K – True Daylight (Photography Standard)

6500 Kelvin - Cool daylight — 6500 K – Cool Daylight (Office/Display)

Temperature (Kelvin)	Appearance	Typical Use
2200 K	Very Warm Amber	Candlelight / Decorative Lamps
2700 K	Warm White	Homes / Restaurants
3000 K	Soft White	Living Rooms / Warm Ambience
3500 K	Neutral White	Retail / Lobbies
4000 K	Cool White	Offices / Showrooms
5000 K	Daylight White	Workshops / Studios
5600 K	True Daylight	Photography Lighting
6500 K	Cool Daylight	Hospitals / Display Areas

Tip: Warmer light (lower K) feels cozy and relaxing; cooler light (higher K) appears brighter and energizing.
