A DC chopper reduced the voltage without producing heat whereas a rheostat
merely provides resistance and builds up heat. I had a rotary chopper
switch on my boat to dim overhead 12 volt lights in the main cabin. However
these were incandescent bulbs and I do not know how or whether they would
work with halogen bulbs.
