Does Two Lights Double the Lumens?

Most likely because Watts are units of power used but Lumens are units of light emitted. Sure, higher wattage bulbs give off more Lumens, but two LED bulbs with the same wattage can give off different amounts of Lumens depending on how efficient the bulb is. ... This is where wattage equivalency comes into play.

Do lumens add together?

Lumens do add up. So if you have one n lumen flashlight and another m lumen flashlight the total luminous flux will be n+m. However interestingly our eyes (and ears) don't operate on a linear scale. 2x the lumens will not be perceived as 2 times the brightness because our eyes and ears work on a logarithmic scale.

Do more lights equal more lumens?

Lumens measure how much light you are getting from a bulb. More lumens means it's a brighter light; fewer lumens means it's a dimmer light. Lumens let you buy the amount of light you want. ... To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens.
