More like resistive coils as ballast, the arc produces enough IR all by itself, no need to have extra IR, just the ballast resistors are placed where they are able to dissipate heat well.
A very interesting open UV arc lamp with nichrome coil ballast resistors. Almost steampunk :-) I saw a Soviet ultraviolet lamp, also from the fifties, for kindergartens. But they used a mercury arc quartz lamp. A job well done.
Yet another unique restoration. Items the majority of the population have never seen, and can only guess as to what they are, and potentially deadly to operate too boot. Well done, keep them coming.
Nice looking "death ray" lamp. Great job at restoration you mentioned everything I was thinking about the lamp (read description after the video), the strain relief looks too modern and it's probably why the wiring was damaged I would imagine the original was a rubber grommet and something like an UL knot. Thanks for sharing this wonderful piece of history with us.
🤨 ~ a genuine medical health lamp or 1950s snake oil? - a lot of women who wanted their face and upper body to have a “tan” would plugs this in and turn the knobs to strike an arc [I assume most did that with their eyes shut as to protect their vision, while using it and then opening their eyes after breaking the arc - the thing was bright enough and made a electrical noise when the arc was stuck] and others wore tint goggles to leave their eyes open while using it (unfortunately leaving them with the reverse appearance of a panda wearing glasses) and a small amount? just looked at it and suffered from welders “arc” eye afterwards. The thing under the arc electrodes is a radiant heater bar with an incandescent pilot bulb = a rough indicator that it was working, I assume the heater & pilot light block was plugged to make it easily replaceable? Another hazard with these was ozone gas - the room it was in had to be ventilated and if the user got the timing wrong they got sun-burn from it. Unfortunately the heater coils didn’t glow red/orange so that radiated a “gentle” heat = an attempt at the heat emitted by the sun. It would be used in the winter when there was not enough sunshine & too cold for sunbathing
Well, it's cool to see this old device works, but the concern is not only the ultraviolet light radiation and vision impermanent issues. it's also about how electric arcs produce ozone, which is very toxic at ground level. Good restore though, pappy 🤓
I love your itty-bitty blue hammer! It reminds me of the much larger body hammers that I've used before. Does it have interchangeable heads? What are the coils for? I watched all the way to the end, expecting to see the coils heat up to cherry red... WTH?
My bigger hammers would only have dented the aluminium I'd rather just take my time and take the dent out it's very slowly I think the coil is not primarily as a heater
It's horrifying people were bathing in UV-C light. The atmosphere blocks UV-C from reaching the ground, so it's pretty much space radiation. I'm not sure what the heating coil is for. I always heard that carbon arc lights produce a lot of heat. I guess it's not enough for sunbathing.
Were the heating coils made to work? Never looked like the heated up, or glowed anyways. Between the coils, is that a small light bulb? Good job on the restoration.
Nah, from a fire point of view it's no worse than a radiant heater - and safer than modern plastic ones. The main danger is to the eyes, carbon arcs are extremely bright and concentrated.
Just replace my microphone and it's far more sensitive than I realised .the microphone is a good 12 meters away from the clock ,I was more concerned about picking up my breathing, thanks for taking the time to make suggestions for improving our channel🙂
