Object A emits more light than Object B. Would it be fair to say that the more luminescent object (Object A) is emitting <em>more high energy photons<em> than Object B? If so, why? If not, why not?

No.

Explanation:

Object A is obviously emitting more energy in the form of light than object B. However, this does not mean that a photon emitted by A has higher energy than one emitted by B.

The energy of a photon depends on its frequency. So, if object A is emitting photons of a lower frequency, it will turn out that its photons have lower energy than those of B. Of course, in this case object A will have to emit more photons per unit time in order to emit a larger amount of light energy than B.
