Black Body line - – (known as Planck’s Law) Is the visual representation on a color diagram that designates the color temperature of a light source expressed as absolute temperature (kelvin)
Color Rendering Index - This is a percentage of a LED light based from a natural light source.
Binning - Sorting LEDs so they all have a similar light output.
Correlated Color Temperature (CCT) - This is the appearance of a LED defined in degree Kelvin.
Kelvin - This is a measurement to describe the color temperature of a light source.
Lumens/Watt - It is the measurement on how well a light source produces light.
