I think I get what you are asking. see you are seeing the Light it self. this works like this:
Light consists of particles named photons. Atoms, all the time, are shooting photons out. But our eyes are only sensible to some of them. So it works like this, an objects atoms get to "excited state" and that is because they shoot out photons. When we observed these shot photons, we call this "seeing" .
You can not see the light. When you look at the lamp, you are not seeing the light. You are actually seeing a very hot metal. When the metal inside the lamp gets very hot, it shoots photons out. That is what you are seeing when you look at a lamp.
About other objects: when certain photons hit to the normal atoms it makes them "excited" . so they again shoot photons out. and when you are seeing other objects using the lamp, you are observing those photons.
So you do not see the photons. Our body uses the observed photons to create a picture of outside. But you can not see a photon, or as you say light. So all we see is the photons that been shot from atoms (when we get those kind of photons, we say we are seeing that object), not the photons itselves.
