We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember saying something
like:

===Carbon lightbulb===
Carbon filament lamps were once used as frost protection heaters in
unheated bathrooms & toilets. A 200w carbon filament lamp provides
about as much light as a 40w bulb, though with an orangey colour. The
advantage is that no electrical wiring or socket is needed, the bulb
is simply put in the bulbholoder and left switched on.

I recall them, yes. Fitted in many bathrooms years ago.

The IR lamp I referred to was this type...

Often used by livestock breeders to warm puppies, etc, but is really
very useful for spot heating of pensioners at very little cost.

A handy heatproof holder can be found here...

The IR lamps can be found much cheaper from farmers' supply stores and
electrical wholesalers.
