Formula of lumens
WebMore lumens means it's a brighter light; fewer lumens means it's a dimmer light. Lumens are to light what. Pounds are to bananas; Gallons are to milk; Lumens let you buy the amount of light you want. So when buying light bulbs, think lumens, not watts. The brightness, or lumen levels, of the lights in your home may vary widely, so here's a rule ... WebThere is no easy conversion between Watts and Lumens without taking into account the light source. Let’s look at the equation for Watts: Watts = Amps x Volts We learned before that Lumens is a measurement of total light output, but there is no mention of light in the equation above. More info on Watts can be found in this video.
