We see both the sun and the bulb pretty much emit photons all over
We see both the sun and the bulb pretty much emit photons all over the UV/Visible/InfraRed spectrum. But do so at different intensities.

By this, we can infer that a photon that escapes as visible light was lucky enough to not suffer too many re-absorption processes. so they will have a small ...
It continuously emits Infra Red radiation (which we cannot see) -these are photons nonetheless.
