Most of the time, we consider heat output to be inefficient. It only works here because heat happens to be its purpose.
You could say it's 0% efficient.
I dunno, I’m seeing some light.
Light is absorbed by materials and ultimately becomes heat.
Doesn't everything ultimately become heat?
Four or five?
and what happens to the energy of said photons once they interact with your retina?
