    Theres a clear coated mercury vapor lamp outside an abandoned warehouse in Brooklyn NY that I pass by occasionally that has been in service since 1973 and its still working now in 2020 and if you look at it now, the glow is so dim it looks like its 20W when in full brightness now. Doesnt illuminate anything but the 2-4 feet around the bulb. I guess its been left alone for novelty sake

    In the town where I grew up, there were the nice old Westinghouse and Powerlite streetlights which used mercury vapour, there were the Westinghouse clamshells and gumball heads made by a company called power lite which belonged to Sylvania, some with the cobra heads, some of which had mercury vapour and some with HPS, possibly metal halide too. One of my favourite things when looking at the streetlights was the slight variations in colour, some were more pinkish, some bluish, some beige, some just pure white, possible the variations of chemical balance, some of them may have been retrofitted with metal halide though I’m not sure.
    Now they’ve all been replaced with LED heads, I know times change, but it is kinda sad, an end of an era. Now they all look the same.

    We have these in the street lights around houses here in Australia. They start up pink, then once they reach full brightness if viewed from a distance you can see a blue/violet halo around it. High pressure sodium is used everywhere else, on the highway and in the city.

    Soviet mercury lamps were used in my hometown everywhere some 30 years ago, except on the main highway which had orange lamps. Falling snow in winter looked beautiful under these. I remember perceiving the lamps to be quite bright, but was unable to read under them or see a grey LCD screen, which was strange. The shell of the bulb was white and looked like a mouse to me.

      However, its sad that most of them were upgraded to LED, LEDs will never outlast this good old MV lamp. Also, LEDs aren't as bright sometimes and they are bad for your eyes. The government hates us using these lights because they want us to install lights like Metal Halide that will fail less than 3 years or explode in a thunderstorm or power outage so we keep spending money on bulbs again, just so the manufacturers and government can get rich.

Also I have seen a house with a Mercury Vapor yard light and I feel as if the yard lights are all 35 years old, they were not as bright as new but they still had a lot of light. All of those Mercury bulbs including the specific one I mentioned I seen have like about 115k hours on them and they seem like they are still going very strong. LEDs are only good for cold weather.

    Hi ! What was the exact role played by Dr. Richard Küch (1860-1915), who was the first head engeneer of the German company Heraeus ? According to the information I found, he invented a way to make top quality quarzglass, but did he also played a role in the development of the mercury lamp itself ? Heraeus created in 1906 a division called Quarzlampen GmbH, and within this division, a company called Original Hanau started to build as one of the first companies in the world UV suntan lights, later combining this with infrared. So, their "Höhensonne" weren't only for cosmetic purposes, but also for medical use, more specificaly to fight rachitis, a result of a lack of vitamin D. Did Küch played whatever role in the invention of mercs, or did he only made a version for his company, anyone ?

    This First Bulb Show, is what I call A "Loop To Loop"Frame BT 28 Bulb! Because it has A Loop on each end of the Arc Tube used as supports! We have some that are still Burning today! Westinghouse made these just after the what I call "Double Strap Open Top Frame" Using Straps of metal to support the Arc Tube! These were Lifeguard Westinghouse as well! The 400 + watt had a Full Strap Frame due to the heaver Arc Tube! Sylvania in 1961 came up with a very odd Mercury vapor Light Bulb Called A Rough Service, or Guarder Frame Lamp! The First 175 watt Bulbs contained a Lifeguard like skinny Arc Tube with Two Starting Resistors one on Top, one on Bottom, And Big battery carbon looking ones at that! The Arc Tube in these had a larger electrode like the Westinghouse! I Have Two of these Bulbs, Sadly with Black Arc Tubes, BUT THEY STILL WORK! The Second one was in a Night Watcher in Ola Arkansas and I remember looking at it up in the fixture when I went to My Grandparents House! I Begged for the Bulb around 3 Years ago from One of our Linemen, I Told Him I was looking at it sense I was a small child, He said the light was installed in 1964 when My Grandparent`s moved up on the street where they lived! and it still works, Al tho not very bright ! And indeed the base starting date is 1964! My other 1964 Sylvania still works as well! ebay has a add for this exact light bulb! It states "You do not have to handle this Mercury Bulb with Kid Gloves" Showing a Arm wearing a Heavy duty Glove Holding one of these AWESOME Bulbs! The Skinny arc Tube was quickly replaced in 1965 with the more common Arc Tube I bet for Copyright Reasons! Have You Ever seen one of these 175 watt Sylvania Girder Frame Bulbs from around 1960-65! And Do You know where I can Get a Good grade one If You Have! I want one that is like New or slightly used! I LOVE Mercury Vapor Light Bulbs especially the CLEAR Ones! The Coated ones You can`t see the works! Here in Ola Arkansas We used Clear Bulbs up until the late 1990s! As did the surrounding Towns! Thank You for showing us Your AWESOME Collection! By the way I have around 30+ Loop to Loop Westinghouse & Phillips 175 watt Bulbs! I think that they tried to make a 250, 400, 700, & 1000 watt for a wile, But the heat they gave caused the frame to squeeze the Arc Tube sometimes Breaking it! So they went to the stranded frames on the Higher wattage Bulbs! Thanks Again!

At the Electrical store, the manager showed me what the New LED light looks like, he lit it up right in the store and while expensive at $150.00, I've spent 3/4 of that trying to get my 8 year old Mercury Vapor to light working each and every night.

    So, in doing some research on positions of streetlights in the context of an emergency evacuation in which there were no rules and drivers were absolutely desperate to get out, I notice that some farm style looking lights are off-white but when looking at them that it is as if at least 2 different spectra are being emitted. It is almost like a parallax experience in which the eyes foveate on two different objects at the same time that are different colors or something but they are not (maybe the combination of cones that are active despite the color perceived or something). I noticed that these lights look green on camera but not visually. Is this because the camera ignores a frequency of light or something but the green and other frequencies are left over in the image? Anyway, these streetlights and those that are green or purple/blue (defective) seem to have an interesting distribution. If drones could see these and jam nighttime traffic in such areas, it might be tough to evacuate.

    Will the bulb only start slowly, explode, will the armature break, just nothing happens or what?
    Will it be same if an cfl or led bulb is inserted there?
    I can only tell by myself that once I was child I screw this kind of lamp to ordinary 230v E27 socket. The light flashed once and the fuse in the house did go.
    Since atleast here in Sweden they use same fitting E27. Also same voltage, you only need that "starter" thing wired there before the E27 socket.
    So thats why im so curious and since this is outdated technology I maybe never get the answer 🤔

      If you put an incandescent lamp on the mercury lamp ballast, the incandescent (if it's 230v) will just run, but a bit more dim than usual. The ballast might try to ignite but not do very much.
      If you put the mercury lamp (or any other arc lamp) on an ordinary lamp socket without ballast, nothing will happen if it happens to not strike the arc. But if it does, the arc will very rapidly heat up, drop in resistance and either the lamp will explode, or the breaker will trip, depending on what happens first.

      more light according to what ? The orange glow vs white/blue/green glow on sodium lights is terrible. Sodium lights produce too many shadows and make it hard to see compared to MV..

      @@jeepsblackpowderandlights4305 shadows are dependent on how the light is defused which is irrelevant to the source of generation. I’m not sure what you’re trying to say makes sense.

      @@Mirroxaphene light per watt also means nothing. Par and lumens are just measurements from tools not what you can actually see. I have UV flourescent bulbs on my aquarium that put out massive amounts of light.. but we cant actually see it. Orange light its inherently much harder to see someone or something on the street, Than it is with a white light from a MV bulb. I have a HPS light and a MV light on my 14 acres. I absolutetly hate the HPS light the power company uses.. sure you can see the dull orange and area it covers is equal to my mv lamp. But you cant see much else.. to where as my ancient MV light which uses clear westinghouse style bulbs and wastes the uv unlike the coated ones. ITS also way beyond its life expentancy, its 20+ years old and most likely 80% dimmer than it should be. It Still lights up people and objects much better than that newer HPS light from the power company.
      I absolutetly hate street lights and highway lights that use HPS. You litterally have to look multiple times before turning and what not to be sure no one is walking accross the street. To where MV is so much easier to see people. Especially the newer phosphorus coated ones

    It’s a truly shit colour, not to mention horribly inefficient, the coated lamp is sooooo much better in every way.

      I think HPS and LED lights are better for street lights, but there is something special about that rare bright green light in dark corners. I personally like it and I even have a few bulbs lying around that I turn on every once in a while.

      @@123four... To me it is more about why they are positioned as they are kind of like the purple defective LED streetlights that, again, are just a factory defect, yet are placed at important points for evacuation routes. Why place them as they do, and both are UV based lights? Is there something special about this frequency of light that can recruit drones or something to stop traffic at important points in an evacuation?
