LED Brightness and Color Temperature
LED (Light Emitting Diode) lights have their brightness measured in lumens. The more lumens, or luminosity, an LED light or fixture has, the brighter it's going to be. Color temperature is measured in Kelvins (K) and affects how the light will appear. Usually the higher the color temperature is, the more lumens, or higher brightness the light will have, but not always. Lights with the same number of lumens can have different color temperatures and while the higher color temperature may appear brighter, they technically have the same level of brightness.
