Consider theatrical halogen lamps, anything from 500 watts to 2000 watts
run at anywhere between 3% and 100%, tho it's rare for some instruments to
ever be run at full stick for any length of time, some lamps can be at
less than full voltage for hours on end.

The lamps last just fine ( I have some which have been in service for 10
years or more (HPL575))


** Plus the BILLIONS of 12V QI downlights that use dimmers at any setting
the owners like.
