Reichert Zetopan Microscope Lamp Holder Replacement - Car Fog/DRL Light (880 Socket)

thingiverse

I inherited a beautiful Reichert Zetopan optical microscope (see below), complete with bright & dark field imaging, polarized transmission, reflection, and mixed modes, multiple polarization stages, multiple light source apertures, and plenty of color and diffusion filters. The only problem was the light source - a mercury arc lamp which required quite a few Amps of current, which I was worried to power on in my house for fear of starting fires, or worse an exploding bulb due to fingerprints or decades of grease boiling off and subsequent release of mercury vapor. So I wanted to retrofit this with as close to an LED point source as possibleI used an Auxito 880 socket LED fog light or daytime running light (DRL) bulb, which you can find here. You can probably use any 880 socket-compatible light, I'm just linking to the one I used.
