Rare vintage Mitsubishi Marathon CFL Bulb!
**Do not watch this video if you have light sensitive epilepsy!**
The word i couldn't get out was "Amalgam" Gas.
This bulb is super unique, because the outer envelope is vacuum sealed with Amalgam gas to help with the lamp discharge.
These were manufactured between 1985 and 1987 before Phillips took mitsubishi to court for patent related issues.
This particular lamp has a quad tube, a built-in glowstarter, and a magnetic preheat ballast.
Enjoy!
