Have you ever heard of Videssence?
https://www.videssence.tv/installations.php They do flourescent lighting for TV studios. When CNN Headlines went on, it was lit with videssence. Its much cooler than incandescent. It has a different look in color which the cameras had to be balanced for. Those large incandescents with the mogul base were used on TV towers. They are 660W. Any new tower being built and those over 1000 feet must have strobe lighting these days. But I think HP Sodium is thee brightest. Artificial sunlight!

Three years ago I was visiting a friend in Washington, DC. He lives in Chevy Chase Park area. The back alley behind his house was still lit with incandescent street lights. It was so odd to see a whole street still lit with incandescent lighting. Though, I liked it. I also have a 1949 GE Form 79 incandescent street light atop my garage that I use every night. It's funny......last year they replaced the high pressure sodium streetlights on my street with some really wimpy LED lights, and the light atop my garage is brighter than the street light out on the street!

They've replaced all but one sodium streetlights in my street with LED's, the one exception is outside our front fence where we still have a low pressure sodium light. However it conked out a few days ago. Phoned the council & they'll come when they can, but there's a very big backlog of jobs because of covid19 so not expecting them anytime soon. I presume we'll be getting an LED job when they get round to fixing it...

 The price was right, free. I like those tubes. They're good for high bay. 16 feet above the floor. The company I worked at, converted to Metal Halide 24 years ago. I took the better quality fixtures with the porcelain enamel shade and the better sockets.

Well they've been & put the new lamp post up with an LED on top, just got to see what it's like when it gets dark in about 3 hours time. I'll miss the orange glow of the old low pressure sodium light...

Well it's now dark & my front garden is lit up with a glaring white light, it will take some getting used to after the relaxing orange sodium light. At least it isn't blue'ish like the earlier LED's were, hope it doesn't light the bedroom up too much...

Fluorescent street lighting

Yup, I hoarded incandescents too. I have far too many, and the supply will outlast me. I've debated selling some off on eBay. Last edited by user181; 10-15-2020 at 05:58 PM.

I also loaded up on 100 watters, including a pile from a wholesale club. I finally sold a bunch of them on eBay because they were taking up too much space & I really don't have much need for them anymore.
What had me thinking of this thread: I live across the street from an old factory complex, still in limited use. I'd never noticed until a few weeks ago that their whole lot uses those fluorescents. A large percentage are stuck on 24/7.

Apparently GE offered some sort of a "cold"climate" option where a thermostat and heater was installed in series with the line power or photocell. You would set the photocell to turn on while it was still a bit brighter outside, or presumably turn the lights on earlier and it would first activate a heater in the lamp head to get the internals and the tubes above freezing, then the thermostat would satisfy and while switching the heater off the lamp would switch on and the ballast would take over from there.

On a Romanian forum I found the answer: the tube where of special construction and had some kind of heater.
I hoarded incadescents too.
