I have used the XHP70 (12V) very successfully as a bulb replacement for a goose neck light source. It needs lots of heat dissipation but with a 4sq in heat sink it works nicely. The idea of using it as light bulb replacement for a Zeiss Standard Fluorescense microscope attachment light source is int...

I got the bulb base installed at a height that more or less centers the bulb filament with the illuminator's parabol...
