Hi all,

Is there any way to build 12/24V operated CFL energy savers, which are normally operated on 110/220V. I need same type method with low voltage operation. Thank you.

hi

it is possible, I try a ready CCFL driver circuit (extracted from a "all-in-one" device, scanner use this) and I connect to the filaments and the lamp works good. Also lamps with open-circuited filaments work by this method.

I used to have a CF bulb in my old van.  an it with a $20.00 cheapie power inverter.  Drew less than a standard dome light and gave off much more light and more pleasant.  Newer van has Luxeon LED fixtures I made myself.
