Hi,
I have a big collection of HID lamps, more than 1000 pieces. Many years I was alone only, now in world is more collectors of modern lamps, too. It was a pity lost TOO MANY HID lamps, that the progress is big. I have e.g. one of first commercial Lucalox lamps, Multi Vapor lamps etc. I think, that is important collect no only old lamps, but new lamps, too. Write to me, what is your collection and what is your interest, if you are specialised. Stan
