light bulbs have efficiency ratings like 100% of electricity
I don't even know where to begin on how wrong this statement is...
90% light +10% heat. Does your explanation still work?
It's other way around (90% heat, 10% light) and yeah my explanation still works.
this is irrelevant but at least in Europe and probably most of the world those old bulbs have been banned and replaced by LED.
Why does your statement still stand?
(Ill aks someone who knows physics and all that stuff maybe ill undesrtand then)
