You can buy halogen replacements, which are pretty much identical
albeit more expensive to buy and less expensive to run.

beware if running them at an angle. We have a load of these, and in the
dining room they fit in a lamp at something like 45 deg. Similarly, another
one fits horizontally. They fail really quickly - looking at them it seems
the filament isn't supported well enough and it drops and breaks. The ones
that are either in pendants or upright in table lamps are great and have
lasted well.

Or you can readily buy dimmable CFLs these days.

Ignoring the fact that many of these give horrible light, you have to be
careful using them with dimmers. Many dimmers (older ones anyway) have a
minimul wattage to work reliably - they won't all drive dimmerable CFLs
reliably.
