Sorry, but these numbers are not accurate. Luminous efficiency of tungsten lightbulbs is typically around 1-3% (depends on voltage and power), and luminous efficiency of LED bulbs is around 10-30%. (https://en.wikipedia.org/wiki/Luminous_efficacy https://en.wikipedia.org/wiki/Luminous_efficacy)
- Iulioh 2y agoYou forgot the part when we used 100W bulbs and now we use 10W led lights. Efficency in the use of energy ti generate the same amount of lumens, because it would be REALLY fun to have a 100W led lamp in my bathroom mirror (my parents still have 2 of these traditional lights ). I mean...energy conversion to lumen is fine but i think it's a little pedantic
- MarkusQ 2y agoGP didn't "forget" it; that 10x improvement in efficiency is the reason we can use 10W bulbs to do the job that used to require a 100W bulb. Looking at energy conversion to lumens isn't "pedantic," it's "correct".
- Iulioh 2y agoYou can be correct and pedantic at the same time, like in this case.
