I must be missing something. A regular resistance heater converts all
the energy into heat, this converts the energy into heat and light.
Unless you need the light, how is a heater based on light bulbs better
than a regular resistance heater?

A conventional heater has to heat the air and heat is continuously being
lost to the environment. Spotlights (or better, the equivalent, purely
infra-red heaters) give you radiant heat directly onto your skin. You
can feel warm with them in a much cooler room and so save energy. They
are often used in factories, loading bays, etc.

That kind of works as long as you're not after best comfort.

Even more economical to run is microwave heating. You can feel nicely warm in a 10C room with that on.
