Another choice is the so-called "2X" bulb that a company called ADLT

What are they? *I assume the 72 watt replacements are halogen, but what

fixtures should have thermal fuse protection, preferably a restable
type.

or a regular fuse or circuit breaker that would blow if a too high a
wattage lamp is used

CFLs run so cool the incandescent rating could likely support a twice
the wattage CFL of a standard incandescent
