| Apr 23, 2014 at 18:08 | comment | added | Kamil | Here where I live I can buy only chinese, bad quality, wrong cold color 12V lamps and they cost 6x more than high quality Osram or Phillips lamp. Led would be better (similar price, good color, but they also need optics). Can we talk only about voltage converter? :) | |

Either replace the entire electronic part with your own transformer (like from disposible flash cameras which work with 1.5v or 3v batteries) or buy 12v CFLs, even with the same standard bases. | |

| Apr 23, 2014 at 16:53 | comment | added | Grant | A more practical power source may be lithium ion or lithium polymer batteries. D cells are not very good at providing high currents, and don't store a whole lot of energy for their size. | |
| Apr 23, 2014 at 16:34 | comment | added | John U | This has been done, without generating mains-like voltage, have a look on Hackaday. | |
