Usually you can't do anything effective about it, it is due to their design. However running them at higher current for some time or running them on half-wave rectified voltage for a while (lower current according to some datasheets in this setup) will help some but most fall back into the flickering state when you run them under normal conditions. A nice site on the flickering behaviour can be found here: http://g3ynh.info/disch_tube/lamp/flame_neon.html.
Sometimes pulse-drive, either by half-wave rectified voltage or simple on/off square pulsing will help somewhat, instead of relying on a steady DC voltage. /Martin On Wednesday, 13 January 2021 at 23:16:18 UTC+1 Pramanicin wrote: > Ugh.
