Color Rendering Index (CRI)
is a comparison of a light source's ability to accurately render the color of an object to that of a standard reference light source. The CRI scale is from 0 to 100, with a value of 100 indicating excellent color rendering. Sunlight and most incandescent lamps have CRI values of 100. CRI values should only be compared with light sources of roughly the same color temperature.
is a measure of light output (lumens) per watt of electrical power needed by the lamp. Lumens measure how much light is emitted. Watts indicate how much electrical power is consumed.
is a way to compare the color of light emitted from different types of lamps. It is often referenced as cool light (slightly blue) or warm light (slightly orange). Incandescent lamps and candles give off warm color temperatures, while sunlight and some fluorescent lamps emit cool color temperatures.
