I have seen posts here and elsewhere with some confusion between what are Lumens and what does Kelvin mean...so here goes
Lumens-a measure of the total quantity of visible light emitted by a source per unit of time. If you are really bored, ANSI has very detailed discussion of how it is measured. Note that the spectral curve (color) of the light source is not a component of the measurement.
I shamelessly lifted the following from Wikipedia.....I could not have been more concise
Kelvin " kelvin is often used as a measure of the color temperature of light sources. 5600K is an arbitrary standard for Daylight aka "D56" Typically the cooler the number, the more red the color appears and the higher the number the bluer. On average, the human eye has the best color discrimination with a 4800K light source.
The difference is significant when you are buying lights and looking at different emitter types.
