Clesta light, possible bad light bulb (L6a)

Today I repaired a light that was not broken.
Problem:
Dr suspected a bad bulb.  After changing the bulb he let it hang by its one wire.  He tested the light and of course it did not work.  Office staff called us in to repair the light.
Cause:
The Belmont bulb is a one wire bulb the rest of the housing from the bulb gets grounded to the metal of the light frame.  If the bulb just hangs it does complete the circuit with the rest of the light. Therefore it would not work.
Remedy:
Make sure bulb is in place when checking its function.

So the Dr did troubleshoot correctly, it was a bad bulb originally.  But when he replaced bulb and tested it by letting it hang down he made a boo-boo.
Please find attach below instructions on how to change the bulb.

DR's name has been held to spare him the expense of embarrassment, since he paid his bill on time.
