All atoms on Earth emit and absorb black body radiation. The LED can be
toggled on/off.  Furthermore the red so-called photons from the LED can
be focused on the resistor or coated to absorb its own radiation.  Yes,
you can also focus T-rays, but such a lens is a two way street unless
you are talking about more advanced technology other than a simple
T-ray lens. The amount of black body radiation entering the LED remains
the same regardless if the LED is emitting so-called photons or not.

Again, in experiment #1 the resistor absorbs the so-called photons from
the LED, but in experiment #2 the LED absorbs its own so-called photons
due to a coating over the LED.  Therefore, if one argues that the
resistor and LED remain at the same temperature in experiment #1 then I
simply point out that the LED therefore must be hotter than the
resistor in experiment #2. :-)
