Not quite. The filament bulb based "resistor" is a much better IR
A manufactured for that purpose resistor, by design, dissipates its
heat through the medium of its body, and would be much better at
keeping said heat right where it was at. The bulbs would, on the
other hand, heat up surrounding elements and chassis parts from a
distance via radiated IR energy.
So how said heat gets handled makes a difference. Paint the bulbs
with a matte black high temp paint, all except for a viewing "window"
at the top of the bulb.
Hahaha... No, the laugh is on you.
