What do all these lighting words mean?
Kelvin, lumens, watts, oh my! Newer bulbs have a Lighting Facts label that will give you all of the details of a particular bulb (similar to a nutrition label on food). For example, we've previously looked to watts to learn a bulb's brightness; that information is now presented in lumens. See our Guide to Reading Lighting Facts for more.
