@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 !

@wide-lite 1000 - That's an Evluma AreaMax AX. There's thousands of these in WA since that's where the company is based. They're the most reliable LED luminaire I've seen to date.
