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...

@SussexEuroSOX
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……

@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.

I tried searching up some of the Sylvania street lights and it only showed me headlight bulbs lol

I have still not yet found firm evidence of tin being used in pink lamps - do you have a spectrum or some other material that proves this?  I would expect tin to desaturate the colour due to its very broad spectrum, more than it saturates it by blue absorption.

They look as if a Nema head went LED?

 Thanks ! They're weird looking from the side !
