Re: [APD] Ballast electronic or magnetic?

There's a local inventor that's made a solid state ballast that gets the
same amount of light, as measured by my Zeiss light meter, at half the
power. it even works on "dead" tubes and as of this week HID lamps. He's
doing the patent thing and has promised me samples for long term evaluation
"soon". He's been here a couple of times with them. They seem to do as
he says, and will indeed strike and light dead tubes.

More as I find out.
