  • Description: More light bulbs are now packaged with a "Lighting Facts" label. Besides lumens, this may include factors like lumens per watt (bulb efficiency); watts (energy used to make the light); correlated color temperature, which indicates cool or warm color (about 2700 Kelvin replicates what we're familiar with in a traditional incandescent); and a color-rendering index (the measurement of a light's appearance on objects).
