Neon resetor values « on: May 10, 2020, 05:46:54 PM » Author: Bulbman256
hello lg! when im done moving (mid to late june) i was thinking of ordering a ton of little neon and argon phosphorus bulbs of amazon. they would be the standard ne2 varity and was wondering what restore value should i use to run the properly on 120v ac. Thanks in advance of any info! :ne2: ;D

What is "resetor"?

If you mean resistor, 8t depends if your bulbs are Ne2 or Ne2H.
"Standard" Ne2 were used with 120..180kOhm,
"High brightness" Ne2H with 33..68kOhm.
I dont think the "standard" are still made, I would guess yours are actually Ne2H.
But the mentioned resistors are the minimum value (maximum current), used to baseline the lamp lifetime.
By reducing the current (so the electrode temperature) you can significantly prolong the life (the life use to be reverse proportional to current^8, so hlalf of tye current means 200x longer life, with the true Neon Ne2H), so even a seemingly small current change may have huge effect on the life.
But at too low currents a space instability may occure, leading to only small spot along the electrodes lit or "dancing" along the rods.
So for a maximum life, use as low current (so as high resistance) as performance in your application allows (considering both brightness, as well as if the instability spot formation could be tolerated or not).
