I think a simple experiment could eliminate what

the basic properties of light. An incandescent

in which a thin tungsten wire is heated by an
electric current into the light emitting
temperature. Therefore, the wire is measured for
its mass and for any lost mass during the long
period of use.

The filament itself gains some mass due to oxidation, and loses some mass because the tungsten gets plated on the inside of the glass envelope.

Note, the filament does not produce the energy that lights it, a power plant (or battery) does. The energy (and therefore relativistic mass" must come from the power plant, and not the filament.

This test is based on the fact of which photon
mass particles are emitted; there must be a
loss of mass,

Photons have no mass. Their mass is less than 18 orders of magnitude less than their energy, inclusive of zero. If they had mass proportional to their energy, gravitational lensing would spread out the spectrum. It does not.
