We have had good luck with using 24 volt Buck/Boost transformers like 
these, http://www.grainger.com/product/SQUARE-D-Buck-Boost-Trans-1H271.  
On Sensor dimmers with loads of 12 and 24 volt incandescent lamps.   We 
did once have a set of these burn up on Leprecon dimmers, I suspect 
there was a filament warming setting, leaking a very low current at all 
times, and they didn't like it one bit, but we have had years of 
flawless installed operation with these on ETC dimming.
