No really. How is this possible? In a mall parking lot, about 35 feet up.

Maintenance personnel removed the lamp. They realized they didn't have a replacement lamp so they kept the lamp there as a sign that the lamp had to be replaced and what kind of lamp to use.

Not a misoLEDist...

Hmm that's possible. But that looks like a difficult option to accomplish. If these are probe-start, what difference would it make if the lamp was screwed and cycling or dead?

Given the 30 or so other identical heads on the lot, I just lowered my opinion of so called "maintenance personnel" even further.

Hmm, I mean I've seen HID lamps unscrew from vibration if they're not screwed in firmly, but the ones I've seen have never completely unscrewed, just enough to break contact. I've gone to change the bulb at work and find the thing is loose and when I screw it in it fires up lol. Happened twice to me at the same building. They were 150W HPS wallpacks with base-up lamps.

Maybe the fixture moves in the wind more than the others around, coupled with a loosely installed lamp resulted in this.

I think Adam (merc) is right. There are too many turns for a mogul lamp to come out completely. Probably done on purpose - running out of fresh 1000 watters seems plausible.

It's really bizarre. I would have just removed the lamp entirely. If it's an entire parking lot the lamp would be the same as all the others, so no need to save it. And if they did want to save it to order more, the lamp isn't doing any good still being up in the fixture. Whole thing makes no sense. Whoever did this doesn't seem to be qualified enough to keep their job.

It could have just been a result of a loosely screwed in lamp. Even on an open circuit ballasts vibrate and a 1kw ballast would have probably produced more than enough vibration.

Any machine is a smoke machine if you operate it wrong enough.

This is a base-up oriented 1000w lamp (heavy bulb) on a relatively tall pole, there is a very good chance this lamp actually unscrewed itself from the lampholder by the fixture vibrating and wobbling in the wind. I have come across countless parking lot fixtures during services, where the issue was the lamp simply unscrewed enough to break contact, while I have never come across a lamp that completely fell out like this, there have been several literally a couple threads away from the edge

Same lamp but from the opposite side here https://www.lighting-gallery.net/gallery/displayimage.php?pos=-153979. All the masts plus fixtures were replaced this fall with LED systems.

Very interesting, I've come across 2 400w cram Mh lamps in cooper shoeboxes that had unscrewed themselves and laying on glass, one was EOL the other was fine, definitely a rare occurrence considering I have been doing this 6 years and only 2-3 times
