Lighting Terminolgy

Watt: The power needed for an application.  Example: you need 100 watts to run a 100-watt light bulb. 

Lumens: The units used to measure the power of light.  Goal – achieve more lumens using fewer watts.

Kelvin: Unit that indicates the color of light, and it’s somewhat counterintuitive:  The lower the Kelvin temperature the warmer the light color; the higher the temperature the cooler the light.
