Regards your comment, for sure, the light bulb is giving off higher energy photons. And they show up brightly when they hit my retinas. But what about the photons coming from my cold leftover lasagna? Has it been heated up by the light bulb? Are those photons of a higher or lower energy level than the ones given off by my eyeballs?
Grab your cold left over lasagna, take it into the hall closet, put a towel at the base of the door so you have no light coming in and tell me how many photons you see coming off your cold lasagna. If you see your lasagna, in the fridge, it is because light from a source in excess of 2000 degrees provided that light.
