A Handy translation between Incandescent Watts and Lumens
Tungsten Incandescent Watt consumption was never a good measure of light output. With the changes in available lighting elements, it is pretty irrelevant but when your brain knows lighting in terms of Watts instead of Lumens, you have to figure out the equivalences every time you need to replace a place a bulb.
For my own convenience I’m putting a handy equivalence table right here.
- 15-watt incandescent bulb = 100 lumens
- 25-watt incandescent bulb = 300 lumens
- 40-watt incandescent bulb = 450 lumens
- 60-watt incandescent bulb = 800 lumens
- 75-watt incandescent bulb = 1050 lumens
- 100-watt incandescent bulb = 1600 lumens
- 150-watt incandescent bulb = 2650 lumens
Watts to Lumens was always variable, halogen was always more efficient, while long life was less efficient than regular bulbs, and clear slightly more efficient than frosted.
