Hi!

I know the failure modes of HPS lamps (cycling, sodium loss, etc.) but I don't know how SOX lamps typically fail, since they work more like a fluorescent tube and contain lots of sodium. My only guess is eventual electrode depletion, but I don't know what that translates to in a well used or EOL SOX lamp. Suppose I have a brand new SOX lamp, run for a few hours a week, how long do you think it may last?

Damn, beat me to it.

@SussexEuroSOX, there are LED NEMA heads, this is one.

Yes, it was an earthquake.
The city I live in had just barely managed to avoid them up until now, but in 2024 we finally became directly affected…
There was hardly any physical damage, but even a little more shaking is enough to be traumatic……

Damn! I don’t think I could handle the ground shaking!

Okay, I just made a request on their page.

Wasn't there some bigger earthquake recently in Japan? Then even if you were further away, even when attenuated, the shake may have reached you...

@James: Here is the spectrum of my Venture MH-DE 70W/UVS/PDX lamp: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-231287
I think that the halide that account for the vapor afterglow is tin, because of the continuous radiation and the fact that tin absorbs the blue part of the spectrum.

Just let me know when you do, I'll let the main guy know.

Sounds great! I do got an FB account. I'll look that group up later

I'll hit you up if I see any.

You could try ti join australian street light collectors on fb and ask.
