The hi efficiency light or the spots?  The spotlights that were forever
failing were indeed wall mounted ES types.  The hi efficiency lamps I have
now are standard bayonet fitting.  At only 12 watts or so, I don't feel bad
about leaving my hallway light on all day so I can see to get into my house
after work.

Never heard this one.  Perhaps a spot would run hotter pointing down ( as
the mostly are) because the silvered side would be uppermost and hindering
the convenction cooling of the gas in the lamp??  Just a guess though.
