My crappy house was making all sorts of weird noises yesterday !

 That's what I'm thinking .

@wide-lite 1000, @xmaslightguy, I do wonder if this level of dust storm is what @dor123 may be experiencing in areas nearby him?
Sounds dangerous... and since I've got severe asthmatic symptoms that develop when it gets too dusty, I think I'll pass in terms of any of that!
One thing I forgot to mention in my last post is the recent wind storm we had... it was sunny out, but the wind gusts kicked up to apparently close to 70mph
at times here. I could actually hear my loft taking a lot of wind upstairs.

@wide-lite 1000, same here when I search for the HID's and certain fixtures... and here soon I plan on utilizing this for my garage a bit more.
Still also finding fluorescent ballasts and lamps easily as well, most for a reasonable price... so this also makes me wonder if it could be due to seller/buyer location.

 Today I ate junk food ! ...And more junk food ! 

 @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 .
