[Rockhounds] Need Help Re Substage Lamp Luminosity

Hi John,
How about asking your electrician to take out the old socket and install a
new socket for which you can find a bulb. OR- There is a Connecticut company
called Absolute Clarity that may have an answer for you.

Eventually I would like to have a petrographic microscope, thin sections are
great to study.

Okay, I admit that 5 years or so ago I bought one of those Japanese (?)
petrographic microscopes on EBay. Paid maybe $800 for it. The scope is more
or less serviceable, but needs to have greater luminosity out of the
substage lamp. That lamp has a 15W bulb. I think 20W would make a big
improvement.

Here's the rub. Off and on for 5 years I've tried emailing/phoning the
company. No response. All I wanted was for them to identify the company that
produced the bulb, so I could see if they could supply a 20W bulb. Most
recently I tried via the "ask seller a question" on EBay. Still no response.
The bulb seems to be of Japanese make, very different contacts at its base.
I took the lamp to a local electrician, but they couldn't find anything from
their suppliers. Likewise, emails to various bulb supply houses produce no
response.

Any ideas from the group?

Thanks.

John
