Glossary of Lighting Terms
Lumen (lm)
A measure of the total amount of visible light emitted by a source. More lumens mean a brighter light.
Lux (lx)
A measure of illuminance, or how much light falls on a specific surface area. One lux is equal to one lumen per square meter (lm/m²).
Watt (W)
A unit of power that measures the energy consumption of a light bulb. With modern LEDs, lumens are a more accurate measure of brightness than watts.
Kelvin (K)
A measure of the color temperature of light. Lower values (2700K-3000K) produce a warm, cozy light, while higher values (4000K-5000K) produce a cool, neutral or bluish light similar to daylight.
Color Rendering Index (CRI)
A scale from 0 to 100 that measures a light source's ability to reveal the colors of objects faithfully in comparison with a natural light source. A CRI of 80 or higher is recommended for most indoor applications.
