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.

I enjoyed the video, thank you for sharing.

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.

I unfortunatly have no parts to trade.I am only missing the inner globe for my lamp.I would really love to find one.thanks shane.

Amazing

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

Low Hz will heat it up .... Like All transformers where they too are sensitive and must have the right number and types of laminations

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!

how do you get carbon rods for the lamps?

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😂

What happened to all your other street light videos

How can I buy an inner globe?

Hello,is this for sale? i have three Adams Bagnall lamps

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!

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

Sources mention 133 Hz, this is the 1st time I hear about 166 and 233.

If I owned a carbon arc lamp like that in this video, I would just throw in a metal halide ballast and bulb.
