Lumen to Kelvin Calculator – Convert Lumens to Approximate Color Temperature
Understanding the color temperature of a light source is essential for setting the right ambiance in your home, office, or workspace. While lumens measure brightness, Kelvins determine the warmth or coolness of light. Our Lumen to Kelvin Calculator provides an easy way to estimate the Kelvin color temperature of a light source based on its lumens, helping you choose the perfect lighting for any setting.
Lumen to Kelvin Calculator
Note: This tool provides an approximate Kelvin value based on typical lighting ranges. Lumens and Kelvin measure different properties and cannot be directly converted scientifically.
What is Lumen to Kelvin Conversion?
While lumens measure brightness and Kelvins measure color temperature, no direct scientific conversion exists. However, our exclusive Lumen to Kelvin Calculator provides an approximate correlation based on typical lighting conditions.
NOTE: This is the first-ever Lumen to Kelvin Calculator developed by the AllBlogThings team.
How to Use This Tool?
Simply enter the lumens (digits without K at the end) of your light source and click the Calculate Kelvin button. The tool will estimate its Kelvin color temperature, helping you understand whether the light is warm, neutral, or cool.
Here's a simple demo:

That's so easy, isn't it?
Common Light Sources & Their Kelvin Range
- Candlelight (1800K) – A soft, warm glow similar to vintage Edison bulbs.
- Warm White (2700K-3000K) – Common for cozy home lighting.
- Neutral White (3500K-4000K) – Great for workspaces and bathrooms.
- Cool White (5000K-6000K) – Ideal for offices, garages, and photography.
- Daylight (6500K+) – Crisp, blue-tinted light resembling natural daylight.
