Wow! Those relics should have been gone in the late 1970’s, early 80’s.

Would you look at that! Gave a up vote.

84w

TXDOT did use these, until they started using LED street lights. These were also in 250W and even 150W. The 150W ones used in underpasses. Plus, these were also available in black finish housing, instead of the light grey housing.

Amazing man 🔥🔥

Do you live in Texas?

Very interesting fixture

As a word of caution, you have to be extremely careful with running these Sylvania 360W Unalux lamps because they were designed to run on HX (high reactance) autotransformer ballasts or 208-277V series choke ballasts instead of CWA (constant wattage autotransformer) ballasts. If the lamp is used on a CWA ballasts for too long, you might damage the lamp or the ballast. This means that they must NEVER be used on most 400W M59 probe start metal halide ballasts since many of them are CWA ballasts. The reason that the Unalux lamps are incompatible with CWA ballasts is because the constant current nature of those ballasts causes the Unalux lamps to run at dangerously high power loadings due to the fact that their arc voltage drops rise very fast during their lives. In the long term, a CWA ballast can get destroyed due to the lamp overloading its primary. In this case, if you want to continue running your Unalux lamp again, it is best to invest in a 400W H33 mercury vapor HX autotransformer ballast or invest in importing a European 220V 50Hz 400W mercury vapor series choke ballast if you have any access to 240V 60Hz supplies at home. Sadly, HX autotransformer ballasts for mercury vapor lamps 250W and above are very hard to find. As far as I can tell, I can see that the fixture appears to have a CWA ballast due to the appearance of 2 dark edges on the flicker bands. A proper HX autotransformer ballast or series choke ballast should only produce narrow dark flicker bands with one dark line in the center. As far as I can tell, the lamp and ballast should be okay if the setup is operated for short test runs. Sadly, I have read that one collector in the lighting community has damaged one of their Unalux lamps by running it on a CWA ballast even though it was for a short test run.

It resembles as GE M-400A from early 1970s through mid 1980s, as well as GE M-400A2 from 1985 to early 2000s, but they are really GE C400, and GE C400-2. There are a couple different of these two. The later ones does have a location of photocell moved from the back to the center of the fixture, and it has a clamp instead of the push lever. These types of fixtures are used in Chicago Illinois then other major cities in the USA.

Team ban led lights (except in screens) not forcing 👇

Born and raised in Chicago, everytime I saw these, I knew I was home! Personally, I thought these were great looking lights. These were mainly used on main artery streets and looked better than the smaller variant for the side streets. I'm on the hunt for one!

Love the sound

The "C" is there

Being from Chicago, I remember those fixtures quite well. The majority of conversion to HPS lighting occurred during the late '70s/early '80s.

Bulb is dead or starter

Where was this installation josh? Ive never seen this one before

My state used M400As exclusively on freeways and major arterial streets. Before the 90's though, they were mercury vapor. They were also the early versions that had the 2 slots at the sides of the GE monogram.

I prefer LEDs

Could you try it with a "ge hid led" bulb?

Awesome!!

I'm searching very hard for one of these!!! I would most likely convert it to a smaller 200 Watt HPS ballast/lamp

Crime was not gone, but at least it became visible. :D

Nice, just have to keep the wire from being stolen like in Saint Paul. MN...

The lights were all removed because they were deemed racist.

Cool channel man! Good work

Why’s it so loud?

Cameron, TX I’d guess. Rare rare rare.

Mmmm F90T17

Ok it’s nice to see one with the orange glow.

Studies typically suggest a proper streetlighting program reduces crime around 20%. The whole idea of these fixtures was to blast light in every possible direction. I’m planning on getting more of these but once again shipping is an absolute pain in the ass.

310W HPS originally.

Wow nice!!!

Pretty cool.

*Promosm*

With EOL!

Dude, these are also one of my top favorite street light models! My city used to have at least a few thousand 250 watt (or 200 watt) HPS OVMs. I vaguely remember seeing them illuminating but now my city is 98% LED. In fact, my profile picture is of a shaded OVM that I found in my city.

do you have an email I can send a picture? I am curious what type of GE lamp I have.

I love the mercury vapor light blue green color and I call the color aqua blue!

Can we just go back to Ceramic Metal Halide And High Pressure Sodium Streetlights...for some reason they are built to last for many years...if they are built strong enough they will last 30+ years....i mean the light bulbs also can be recycled to just look at how their made

Nice fixture: sounds like the "Cicada band," was there for extra effect...

good i enjoyed the mercury vapor lights

.

Most epic starter

Wow nice where is it?

❤

The 100-watt A-23 mercury vapor lamp is my favorite mercury lamp type. My high school had these surface mounted Downlight fixtures mounted under a concrete canopy at about 30 feet high which were lamped with this type of bulb (I don’t know what make they were since they were so high up). The school was built in the early 1970’s, and some of these fixtures are still in use, as some fixtures were replaced with new different type of fixture. I kind of doubt any of the original fixtures still have original lamps and ballasts though. I have some of these lamps in my collection in /DX, /C and clear, although my /C and clear bulbs are GE.

It seems like the starter is going bad

This Westinghouse mercury vapor lamp is Chinese and of poor quality. Only 10,000 hour life as compared to US made lamps with 24,000+ life expectance.
