Current thoughts on how we might make our own gas filled light bulbs in the future.
- Blow glass tubes.
- Build in a electrode at each end.
- Evacuate by using several old refrigeration compressors in series. I have tested refrigeration compressors as
vacuum pumps. They pull a pretty good vacuum.
- Fill with sodium, mercury, or other substance yet to be determined.
- Seal at a given low pressure.
- Apply high voltage to start and a lower voltage to run. The longer the tube, and the higher the pressure, the
greater the voltage of operation.
Would need to be further developed and tested.
