OK, ditch all of those pathetic little light sources: XBOs, HBOs, halogen, and especially those weak-kneed, new-fangled LED things! Below is the microscope light you all have been waiting for, languishing somewhere in an antique vendor's back room:

And, if you need the instructions:

(Please, someone buy at least the instruction book, to post here. Looks like a hoot!)

Re: The Next Big Thing, or, Back To The Future
Sometimes a new very specific use is found for an archaic method, but I doubt that carbon arc lamps have any use besides a museum item.
If anyone thinks otherwise, then before actually turning on this lamp, take precautions against strong UV irradiation.

It looks like it could blow your eyeballs out of the back of your head.

Too many 'projects'
Re: The Next Big Thing, or, Back To The Future
Thanks Michael for the link to interesting and enjoyable reviews of the history of carbon arc lamps. It puts some perspective into the plus and minus of early electric lamps in comparison to the gas, oil and coal devices.
Re: The Next Big Thing, or, Back To The Future
One of the members of our microscopy group once demonstrated an arc beam projection microscope. It used a thick glass filter against ir radiation and was able to project an acceptable image of ca. 0,8m diameter in a dimly lit room. A Zeiss projection microscope was the first big investment of our group ca. 100 years ago costing several thousand Deutsche Mark. This must have been an incredible sum at this time!
With the older carbon arc lamps you had to adjust the carbon sticks permanently by hand. Later they invented clockworks to advance the carbon sticks. One of our members first job as a teenager at the group meetings was exactly this tending of the projector lamp. This was in the late 1950s.
