Do you think you can stretch to 18W Jon then we can put some in service in some random shops and offices lol

Could do but it wont work right because i dont have krypton gas (yet) so itll be straight argon, should be ok but i dont know

This is awesome. Have you figured what was causing the contamination-like EOL in your previous lamps ?
eclipsislamps   [17 May, 2020 at 09:29 PM]
Insufficient vacuum quality and no method to heat it well to remove moisture from the glass, I now use an argon helium blend at high pressure to get the tube very hot at low current due to the high voltage drop. The contaminent that caused the failure was water

You heat it by discharge through a temporary fill ?
eclipsislamps   [18 May, 2020 at 02:07 PM]
yes
Ash   [18 May, 2020 at 10:25 PM]
Any reason why this way and not with a diffuse flame or similar ?
