Really well explained. Thanks. So the input choke coil with various taps limits the total lamp current. The carbon magnetic lifting coil sets the arc voltage. Ingenious. I completely get why running at a lower frequency will burn out the coils- you need the coil to have a higher inductance (or magnetism storage time between cycles) to limit the current. At DC, it'd be almost a dead short.
One thing I learned is this: "Be very careful when plugging in and using antique electrical equipment. You never know what condition it is in. You run the risk of fire or electrocution." I build small high voltage devices for a hobby and have destroyed some of the machines I have built. Study EVERYTHING you can to avoid any issues. ALWAYS SAFETY FIRST. I can't preach it enough.
Thank You. I've been involved with electricity, radio, and electronics for 70 years and I didn't know anything about these lamps. I thought they were only a creature of edison's DC dementia. Of course I have always been interested in big search lights.. but these AC streetlights are new territory.
that is one awesome lamp. coincidentally I own a 400 watt metal halide Hang-A-Light, made by SouthWire which works on the same principle as an arc lamp. metal halide lamps, hitting the market in the early 1960s, are more or less an outgrowth of the mercury vapor lamp. which was used commercially since around 1930. One could argue the arc lamp was the most important light source ever invented as it would pave the way to mercury vapor, metal halide, high pressure sodium, low pressure sodium, fluorescent and neon all of which use an electric arc.
Not to mention that gas discharge was a major gateway into learning how different elemental materials can affect the spectrum you get! If we didn't find out how to draw an arc with carbons, we wouldn't have later learned that you could put elemental sodium into an insulated tube, fire current through it and get the spectra for sodium with it... and us Brits would have been SoL during the energy crisis in the 1970s without that breakthrough because we'd still be running incandescent sources lol
It's a little bit of a stretch to call fluorescent and neon an "arc". It's a plasma discharge, and very similar to an arc, but there's a few key differences. Namely the heat.
St Petersburg had thousands of street lights with carbon arc lamps as early as 1870s! It was one of the first cities in the world with electric lighting, the Russians loved those things, all other big cities in Russia had electric lights after a while way before the filament bulb was even invented. Carbon arc lamps were actually invented in 1805, think about that, 1805 the first electric light was invented, but its weird because there ancient texts describing electric arcs that produce bright light a thousand years before 1805, thats wicked even if the texts are mere experiments but the fact that we today think people were stupid back then is an insult to humanity, first engines were already being built in workshops by 15th century, engineers experimenting with coal dust and gunpowder dust to make a piston in a cylinders move up and down, the piston in a cylinder itself is old as civilisation itself, even being used by Romans to pump water out of wells using steam!
A beautiful lamp - and a fair warning. I'll probably never ever see one in person, but it's always nice to learn about antique tech. Watch out for asbestos! The fraying insulation on the wires inside made me cringe. And I'm surprised to be the only one to mention asbestos here...
actually boor-silicate glass doesn't filter out UV (that's the type of glass that would be used for the inner tube because of the need for it to withstand high temperatures) regular glass does tho, the type that would be used for the outer globe, and don't look at the arc, there's a reason why welding masks are used when welding instead of just a pane of glass I doubt running this indoors would be a great idea since the light creates a lot of carbon monoxide, I doubt it's gonna be fully concealed by the inner tube that encloses it.
Boroscilicate does still filter out some ultraviolet. It's transmissive to UV up to 300nm so anything from UVA to UVB can easily pass through. A lot of reptile specific lighting sources are made with this glass for that reason. Glasses like soda lime are opaque to almost all UV. Soda lime is also extremely cheap, therefore is used in normal incandescent lamps and for the outer envelope of gas discharge lamps unless a UV output is needed, in which case boroscilicate is used. If you need 254nm UV (UVC also known as short-wave UV) though, you can't beat Quartz. It's completely transparent to UVA, UVB, UVC and so is used for germicidal lamps. Quartz is also very temperature resistant and has very high glass transition and melting points. This makes it ideal for gas discharge lighting where the arc tube temperatures can readily exceed 1,000*c, which is more than enough to soften and melt regular glass.
I've tried stacking filters to record the eclipse since I didn't have a 12+ stops ND filter. Reflections between filters do a great job of blurring out details. For the arc lamp, you can probably get away with max stop on the lens aperture and 1/2000 exposure on a half-decent camera. Most phones and entry-level cameras don't let you get down to this sort of detail though.

Beautiful lamp! It was interesting to hear your discussion at the beginning. I have dealt with odd-frequency and DC motors before and had to build frequency converters before. I need to try and locate a high frequency carbon lamp to run with a frequency converter. I bet the sound will be different!
Arc lighting has been around within the 1980s and probably 1990s and maybe early on before even the early 2000s and trust me it is still used today. Most people are mostly about LED technology but most of the neighborhoods in town and even highways they still rely on arc lighting.
Arc lighting has been around much longer than that! carbon arc lamps were produced in the mid to late 1800s to replace gas and they were also more power dense and efficient than incandescent lamps at the time. Modern gas discharge lighting shares the same bones as these carbon arc lamps, but due to advancements in "shoving random stuff into a tube and blasting it with current for science" we have extremely tight control over all the parameters that affect the efficiency of the lamp such as the arc voltage, current, arc length, the quantity and types of elements that are in the discharge tube, the pressures that those elements exist in there at and so on. It's actually impressive to me still that we can have arc lamps with an almost 100 CRI. I have a couple of ceramic 70w metal halide lamps that claim a 95 CRI and an efficacy of 97 lumens per watt!!
21:29 now in the early 2000s in the 1990s are climbing such as mercury vapor, lights or high-pressure, sodium lights deluxe similar to lamps, like these are starting to appear everywhere in cities all over because arc lighting within cities are starting to become more common
And I’m pretty sure this is extremely bright even the reflections on the walls nearby were uncomfortable to look at. And heat from such a tiny little lamp was just staggering It was almost powerful enough to admit the entire day in direct sunlight
And since it also has a bit of a blue screen tint, I have a strong feeling that admits a very large amount of UV from that example of the uranium glass Enemy have a possible large amount within the UVB range and also UVC You should wear sunscreen near this
Arc lighting used to be very expensive because people and the villagers thought it was the future, but as the years go by arch lighting, starts to spread everywhere and becoming more cheaper and cheaper until it eventually reaches every Area of the Earth. Neighborhoods towns, cities, and even highways that’s why our lining used to be the mainstay within the lighting universe
I don't doubt that electrical was not standardized back in the day that carbon arc lamps were used. Back then, that was during the civil war and shortly after. During the civil war, electricity didn't really have a use like it does today. In fact, during the civil war, electricity was a luxury item that only the super rich and powerful people would enjoy. Around the World War 1, electricity became standardized and 60 Hertz AC became the normal operations. Around World War 2, electricity became standard equipment in homes. But carbon arc lamps were used even after incandescent came around. You know how gymnasiums, roads, factories, and such have mercury vapor and metal halide lights? Well, the carbon arc lamp was the "metal halide" back in the civil war era, Titanic days, and those eras of time. And, the operation of carbon arc lamps is just like that of an MH or mercury vapor. Electric jumps the gap between two rods or electrodes and forms an arc and generates light. MH and mercury vapor work that way too. Only difference is that the arc in carbon arc lamps is in the air. MH and mercury vapor are in an arc tube in a glass bulb. But, your carbon arc lamp is an HID light source, high intensity discharge. However, I would just drop in a metal halide ballast into the Adams Bagnal lamp and convert it to metal halide. If it a DC lamp, you might have a better time powering it but even then, it is second to being impossible to do. And, parts are basically non existent at this point. And, troubleshooting will be a major pain. That is why I always like to throw in a metal halide ballast and bulb into those lamps so I don't have to worry about your warnings. And, metal halide ballast and bulb is child's play to find. Metal halide ballast and bulb are "give-me" basically, child's play to find. That easy to find. Learning how to walk is harder than finding a metal halide ballast and bulb. But carbon arc lamp parts? Impossible to find. Good luck with your lamp!
Converting it to metal halide would be ruining the one thing that makes that lamp interesting and historically valuable. If you want to safely run it on 60hz, just put extra inductance in series with the whole lamp to reduce the current. It's no different than thinking 'Huh, my Van Gogh painting is getting cracks from sitting in the sun. Oh i know! I'll throw the original canvas away and just put in a printed copy with digitally removed cracks!' Just get a modern look alike if you want the looks of a 19th century lantern, don't go around destroying those increasingly rare pieces.
22:16 I didn’t even know that this would also mean a way to attract an angry mob it is not a devilish force. It’s the future back then sure was a mainstay now, but it was the future back then.
He lives in Kansas, there are a lot of VERY religious people in that state, it wouldn’t surprise me if they still believe they are satanic and avoid them!
The great thing about this lamp is that you just replace the carboon rods and lamp can keep operating for centuries Not like todays lamps (like Incondecent, MetalHalide, MercuryVapor, SOX, SON, and god no LED'), you cannot replace anything inside there Once they stop making them (SOX, MercuryVapor) or ban them (incondecent, CFL), because people like to ban stuff now, you are out of luck if you want to use them for whatever reason With carbon lamps, as long as you can get some carboon rods (which you will probably be able to do for centuries), and know how to fix things if they break, you will be able to use this carboon lamps for a long time
Filament bulbs must have vacuum inside, the Soviets tried to make replaceable filament bulbs but they all failed, they came up with a method of bulb that would connect to an lamp that would create the vacuum inside the bulb, this worked but by 100 insertions the seals were so worn the vacuum failed not to mention the complexity and cost of manufacturing the thing outweighed all benefits. The technology is more the case of limitation rather than the manufacturer in this case.
@@Mirroxaphene I'd look at speeding up a true sine 60hz inverter, check controller IC datasheet, many support 0-400Hz for VFD and aviation power applications.
just use a VFD, or if your brave, a class D car audio amplifier, even a fairly modest one will have a +- 150v rail supply to the output section., would run one of these, jsut need a signal generator to feed it the desired frequency (and you have just made your own VFD but i digress)
For future reference of using tablets or phones to record videos, as long as circumstances don't prove otherwise, you can use the flashlight of the phone or tablet you're recording with as the light source for the shots. That of course isn't that valid in this video's case, but it's a great tool to take advantage of.
Any one know what the running or operating time would be on a set of rods , would they have used them sparingly so to get a number of uses or would they be turned on and the rods used up in one use
@@tripplefives1402 Westingouse standardized single phase 133 Hz but later changed to 2 and 3 phase 60 Hz because Nikola Tesla's induction motor worked better on it.
@@Mirroxaphene Thanks for the answer, now it makes sense. It probably saturates itself with CO2 until there is not much free oxygen left which acts like a an early form of inert gas filling, i guess.
I wouldn't - unless the original internals are absolutely munted. If they were still in serviceable condition I'd rather build a 133Hz inverter and continue operating it with carbons. Failing that, a 400w 6000K MH wouldn't do too bad as a stand-in for the carbons. But you lose a lot of colour accuracy since most high colour temp MH lamps are only about 60-80CRI. Carbon arc is 100CRI as is incandescent.
@@DigBipper188You are right about that. The new stuff will never replace the old. If you are only wanting to fire up an Adams Bagnal lamp on the original carbons, it may be fine for say a hobbyist. However, the problem is when you need to replace the carbons, those carbons aren't made anymore, I seriously doubt that the original people who made that lamp are even alive anymore, so you'll have plenty of problems finding carbons for it. And even if you manage to find carbons, which chances of that are second to none, you will have plenty of problems finding the opportunity to light it. Like I said in a previous comment, and he said in the video, those lamps were intended to operate on very high frequency AC, try 360 cycles or something like that, but even if I am right on, good luck finding access to that high of frequency. I guess you can try wiring that lamp to the red and blue leads of a high frequency instant start electronic fluorescent light ballast but I wouldn't recommend it. In fact, I would STRONGLY advise against using a fluorescent light ballast to step up the frequency like that. You can damage the ballast and maybe even the Adams Bagnal lamp doing that, can even catch fire. Not to mention that carbons are a fire hazard. That is what happened in the Iroquois Chicago Theater in 1908, which caused the curtains to catch fire. That in turn led to the development of the crash bar, if you ever wander. It was a carbon arc stage light that caught the draperies which caused the theater to go up which claimed 700 plus lives. Yes, a carbon lamp caused all of that madness, or so I'm told. I only brought it up to prove my point. If the Adams Bagnal lamp operates on DC, just series batteries together and you're there. But an AC model might be a problem. That's why I prefer to convert it to metal halide and use a 6500k MH bulb. Yes, at the time of the Civil War, WW 1 and 2, Titanic, Lusitania, and those eras, carbon lamps were the hot dog back then. Carbons were the precursor to MH, mercury vapor, high pressure sodium, and fluorescent lights. In fact, carbons worked on the same principle and idea as fluorescent, MH, and mercury vapor.

They seem to be multiples of 3,600
@@Mirroxaphene Did you actually see arc lamps rated for that? 133 Hz is the highest I can find about historical distribution.
@@tripplefives1402 Westingouse standardized single phase 133 Hz but later changed to 2 and 3 phase 60 Hz because Nikola Tesla's induction motor worked better on it.
Do you have an email? I'll send you some pictures about this lamp.
i have three.
But two of the lights are missing shades😂
turn it on already
Why is there an inner globe?
@@Dilophi helps keep the oxygen off the carbon rods to extend the runtime.
@@Mirroxaphene Thanks for the answer, now it makes sense. It probably saturates itself with CO2 until there is not much free oxygen left which acts like a an early form of inert gas filling, i guess.
@@Dilophi that’s exactly what it does.
Did you say hertz or HURTS lol!😂
Word up dude... People should know better to f**k with electricity if they aren't fully trained
Hahahaha that is so funny that people just think they can use something that is 100 years old....lol Super cool lamp....
If I owned a carbon arc lamp like that in this video, I would just throw in a metal halide ballast and bulb.
I wouldn't - unless the original internals are absolutely munted.
If they were still in serviceable condition I'd rather build a 133Hz inverter and continue operating it with carbons.
Failing that, a 400w 6000K MH wouldn't do too bad as a stand-in for the carbons. But you lose a lot of colour accuracy since most high colour temp MH lamps are only about 60-80CRI. Carbon arc is 100CRI as is incandescent.
@@manitoba-op4jx yeah :) Funny how variable what is essentially a tiny little tungsten resistor can be when you vary the energy through it :)
@@DigBipper188You are right about that. The new stuff will never replace the old. If you are only wanting to fire up an Adams Bagnal lamp on the original carbons, it may be fine for say a hobbyist. However, the problem is when you need to replace the carbons, those carbons aren't made anymore, I seriously doubt that the original people who made that lamp are even alive anymore, so you'll have plenty of problems finding carbons for it. And even if you manage to find carbons, which chances of that are second to none, you will have plenty of problems finding the opportunity to light it. Like I said in a previous comment, and he said in the video, those lamps were intended to operate on very high frequency AC, try 360 cycles or something like that, but even if I am right on, good luck finding access to that high of frequency. I guess you can try wiring that lamp to the red and blue leads of a high frequency instant start electronic fluorescent light ballast but I wouldn't recommend it. In fact, I would STRONGLY advise against using a fluorescent light ballast to step up the frequency like that. You can damage the ballast and maybe even the Adams Bagnal lamp doing that, can even catch fire. Not to mention that carbons are a fire hazard. That is what happened in the Iroquois Chicago Theater in 1908, which caused the curtains to catch fire. That in turn led to the development of the crash bar, if you ever wander. It was a carbon arc stage light that caught the draperies which caused the theater to go up which claimed 700 plus lives. Yes, a carbon lamp caused all of that madness, or so I'm told. I only brought it up to prove my point. If the Adams Bagnal lamp operates on DC, just series batteries together and you're there. But an AC model might be a problem. That's why I prefer to convert it to metal halide and use a 6500k MH bulb. Yes, at the time of the Civil War, WW 1 and 2, Titanic, Lusitania, and those eras, carbon lamps were the hot dog back then. Carbons were the precursor to MH, mercury vapor, high pressure sodium, and fluorescent lights. In fact, carbons worked on the same principle and idea as fluorescent, MH, and mercury vapor.
i did go back and still heard adams vaginal lamp...
Blablablabla
@@bussi7859 absolutely. What’s really crazy is we haven’t learned that until the last three years which is absolutely mind blowing.
