Hi!
Those ballasts are available for around $150 in aquaristic shops, and
are told to have much better efficiency, prolong the life of the bulb etc.
I was unable to find any schematics, or even ICs of which I could use at
least the datasheets. Anyone has links, or whatever might help me?
Thanks, Ragnar |

Digital ballast?? In the sense that they use on-off high frequency
switching . . .
