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!!

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 finest example of the technology in operation on video anywhere. Jeff Behary has the only other (2) videos but they are a mere few seconds long with no commentary. To be sure, this lamp IS emitting vast quantities of ultraviolet light, but all of it is absorbed by the glass envelope except for the 365nm "I" line, which is relatively harmless. The smell test is adequate here because the lamp envelope for a device of this age is either going to be fused quartz, which will admit all wavelengths of UV down to the "vacuum UV", or it isn't and is made of glass which is sufficiently protective. The "ozone free" lamps which add a small measure of titanium oxide to the fused quartz to block the 185nm line that produces ozone while continuing to admit the 254nm line, are a relatively recent invention and definitely did not exist in this lamp's era. Subscribed.

I have researched RF lamps and fixtures and the fixtures themselves were only made from late 1939 until 1942 because of the amount of copper the ballasts used and the increased rationing of precious materials during WWII and never made again however the replacement lamp, F85T10 lamp was available until the mid 1960s. This 450 watt mercury vapor "desk" lamp most certainly has more in common with the rectified fluorescent than a standard mercury vapor lamp which would likely date it no later than the early 40s. The only tubular mercury vapor lamp I've heard of is the H3000 A9 3000 watt industrial high bay, 132,000 lumens, in my 1954 GE lamp catalog.

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.

Very interesting lamp. The first time I have seen such a Cooper Hewitt lamp. The UV wavelength responsible for ozone production is at 185 nm, while the DNA damaging wavelength at approximately 254 nm in the spectrum of mercury does not produce ozone. There may still be some 254 nm transmitted depending on the glass though, so it may be best to limit exposure to it anyway.

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.

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.

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 opaque 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.

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
