That’s good to know. Thanks!
850 mm is usually what is sold as 50W.
It’s not the lenght but the diameter you should worry about. If this is the same slim tubes as the typical K40 and larger, then they won’t last long.
The diameter decides how much gas is inside it - and that’s your duration or “on-time”. Slim tube, even with the best regeneration won’t last that long.
It’s a 50mm diameter tube (not one of the slim ones).
