Tubes were purchased in 2018 to use with Lampizator but did not start using them until late 2019/early 2020. I have way too many tubes and raising money to try some other tubes in the Lampizator. My guess is the tubes has about ~200hrs or so.
This are regular PX25 and not the Ricardo Kron RK versions.
Looking for 525+ shipping + paypal if you are not using friends and family option.
I will post pictures later tonight or tomorrow.
