That "Cost/Benefit" analysis would have to take into account the changes
in pricing of CFLs.  If you're paying $20 each, you may not ever get back
sufficient return on investment.

BUT,...
If you're paying $1 each for them, the ROI is substantial.

Howzbout LED lights?  (where spectral characteristics are non-critical)
Those are happy with low voltage.

Last time that I tried to get 12V flourescents was 25 years ago.
Hopefully they have improved the quality since then!


OB_SUBJECT_LINE: does anybody make a USB powered CFL?   :-)
