It'd be amazing if these still worked.

I wonder if they still do, sometimes places leave long disabled fixtures up.

There's an old RO-JACK'S near me (RO-JACK'S was a small local supermarket that expanded too fast and went bankrupt once the bills came.) i don't remember much about it because they went out of buisness about 10 years ago, but back to my point ; Looking through the glass window of the gutted store, There are some highbays that look like there from the 70's or so possibly old mercury vapor highbays. There are newish fluorescent lights that appear to be T8's suspended below the few highbays (possibly late 90's to 2000) I hope i can get one.

I've seen something like that here too, a local Rona Hardware has some old 1 kW MV fixtures above the current T8 striplights.

And a parking garage here has some old and out of service recessed fixtures that were replaced by highbays.

My guess is that the highbays were disconnected a long time ago and never taken down. But now all the lights are out of service and i don't see any new tennats.

I have thought of taking the Norelcos with a bulb changer and put in chinese bulbs as exchanges when no ones looking

the only bulb changer i know of is the human hand.

They do make a bulb changer! Its a pole with a rubber cage-like thing on the end that grasps the bulb. I used to do that at work.

Yep I've seen them at the box stores before, they have different cage shapes for differently shaped lamps.

Wonder how it grasps a CFL. Do they make 'em for mercury vapor/MH lamps?

What do you know, they do make them for HID lamps and plunger based fluorescent lamps too.

odd.

It would be funny if ya took the bulb amd replaced it with a chinese one, then came back a few days later and saw they replaced it with a Champion one, like ya have in your gallery.And it was on when ya saw it too!

I scored an old Norelco like that. It was where I worked at the time, and I swapped it with a same wattage GE. The Norelco had hardly been used, and the GE will probably see 30+ years there of hardly any use.
