@suzukir122 : My younger brother wound up in a duststorm years ago in Arizona . He has photos from inside his car . It wound up completely black for a minute or 2 !

 Not that I've ever seen .

 I wonder if the issue has to do with where either you or the seller lives ? I can find hundreds of HID lamps/fixtures/parts listed on eBay as we speak .

https://www.scribd.com/document/132183345/GE-1984-Lamp-Catalog  Page 45 + 46 only say "ENCLOSED FIXTURE ONLY" if the 400w lamp is burned other than VBU or VBD +-15°.  Since your lamp is new , I see no problem ! The assembly plant I work in was lit by unprotected 400w M-59 lamps for 20 years. The maintenence morons NEVER replaced a lamp until it went out ! In that time I only saw ONE non-passive EOL in over 100+ lamps !

 Unprotected MH lamps were used for years . Yes , it's possible but unlikely for a MH to go BOOM ! Of all of the non-passive EOL lamps I've seen in the wild , a vast majority of them never penetrated the outer bulb .  The likelyhood of non-passive EOL increases dramatically as EOL approaches .

 Never gonna happen .

Nothing severe here, been warm(a fair bit above normal) & dry with a bit of wind the past few days (example: its currently 70, 9% humidity, some wind (and ofcourse with such conditions 'red flag warning' issued))

Yep a sandstorm - or dust-storm for that matter - would be interesting to experience!
(I have gotten low-end dust-storm before, one thing can say is if you see that coming towards you, don't stay outside (atleast not without a mask).. that crap will mess up your throat for a couple days. .lol. )

It’s packed away deep and I’ve not looked at it for ages now as it annoys me when I see it.
When I do next uncover it I’ll send you photos but it won’t be for a while.

I've always wondered what sandstorms are like, and have seen glimpses of how they are through some pretty intense videos of them on YouTube.
Down here we've got interesting weather as well... serious temperature ups and downs expected throughout the week... 71 degrees on Sunday,
severe weather threat for Sunday night, followed by snow showers on Monday with highs only in the 30's, and highs only the 20's on Tuesday.

See how many haze we have here now at Kiryat Ata. We have a sandstorm here in Israel, and in the south it is severe.
