Carbon Arc light demo

Larry Parker from Mole Richardson demos a Carbon Arc light with a guest appearance by Rodrigo Prieto, ASC :)

[@covert0overt_810]

The light quality is unreal...

[@peterrivney552]

Just like the sun ...back in the '70's-'80's my buddy's parents owned a drive-in movie theater and had carbon arc projectors ... I learned a little bit about them they have better light then the bulbs they use today. The mirror in the back of the projector is very expensive I remember Ted telling me about $1,000. Bak then to reflect the light to the film .. The light is just like the sun burn your eyes that have the dark green glass window to adjust the arc ...

[@covert0overt_810]

@@peterrivney552 Fantastic --- back then you needed those big arcs to light up those big screens... movies are so clinical now.. too clean.. cold... no emotion..

@@covert0overt_810 if blasting your actors with so much heat they can barely stand to act is emotion, i dont want it. not to mention the UV rays lmao

[@lawabidingcitizen5153]

@@12gauge_shawtyy UV rays can be filtered out without degrading the quality with a piece of the right type of glass, and the actors can also stand further away or a smaller lamp can be used, the reason we don't use this type of lighting anymore is because they're inefficient and operation isn't nearly as trivial or as fire safe as any of the alternatives

[@BradiKal61]

When you hear the term "lights, camera, action", that dates back to the earlier days of filmmaking when these lights were not turned on until just before the camera was ready to roll. As you can hear the guy in the video say the carbon rods only last for a certain limited amount of time so they tried to minimize the amount of time they were burning when the camera wasn't rolling. In those days you had one man per light so that they could quickly turn them on and shoot and then shut them off. These days lighting crews are a lot smaller because modern lights don't need the kind of constant attention, reloading, and adjusting that the arc lights did. A good carbon arc operator could adjust the speed at which the worm drive fed in the carbon rod so that it burned most efficiently and maintained proper spark gap during the burning process. having the carbons contact each other or feed too slowly until the gap was too big would negatively affect the quality of light.

[@watchguy7986]

That is so cool!!! My grandpa who was an electrician said the brightest thing he ever saw was a high voltage arc

During a wide-ranging interview that celebrated the 30th anniversary of "Home Alone," Columbus told Insider that he had heard about Rogen and Evans thinking "Angels with Filthy Souls" is real. And he has a theory on why it's tricked so many moviewatchers. "'Home Alone' is one of the last films shot with an old carbon-arc lighting system that was popular back in the 1940s through 1960s for Technicolor films," the director explained. "That means you have to put a carbon piece of charcoal into each lamp and it creates a warmer and richer light to shoot." Columbus said the movie's cinematographer, Julia Macat, insisted on doing the lighting this way for the entire film. The result is that "Home Alone" has a warm and rich look, perfect for a holiday movie - and when you're trying to imitate the look and feel of an old movie. "We also shot the 'Angels with Filthy Souls' scene the same way," Columbus said. "That richness of black and white made it look like a movie from that era and I think that's why some people think it's a real movie."

[@CeruleanFilms]

Are there gels that can create the arc look on standard tungsten lamps? Asking because I own a set of ARRI 650's and love Julio's work on Home Alone.

[@twizz420]

I thought it was a real movie until like last year ffs

[@stoopidhaters]

Ok, but what about the actors eyes? These lamps produce UV. No wonder Trump's Face is orange.

Ran a Super Trooper Arc Spotlight for my high school's A/V department back in the 70s. What a beast.

[@jacksonurenmusic]

Those things are huge! Impressive!

[@dwp1970]

I think we had just the Strong Trooper in my school always fun to run and took a bit of skill to align the carbons correctly.

[@smk242]

Just found a second carbon rod made by General Electric Company here in the woods, they must date back to WW2 and were used in one of these carbon arc lights I assume; there was a lot going on here during WW2 where we live.Thanks for the video!

[@leokimvideo]

I saw these in big studio set ups on a film in the 1990's. The light is amazing but changing out the rods is risky business. With today's OH&S laws these old lighting beasts would be seen as being too dangerous.

now , imagine you are on a set , in a costume (godzilla for example ) and these lights are on a catwalk over head. doing take after take after take with these things running. they said that the godzilla suit operator could only do his stint for minutes at a time because of these lights .

[@aqueento]

Amazing!

[@srfurley]

Haven’t seen one used for quite a few years now. The last time was at St. Pancras station in London before it was converted for Eurostar; don’t know what the production was. I think it’s all HMIs now.

[@kkteutsch6416]

A ingenious mechanic jig permits to mantain an ideal shift of distance on carbon contacts as long as the material is progressivily left by the voltaic arc that is transformed into light...

[@Jim-H]

I think they used these when filming Billy Jack and Easy Rider.

[@goodoldstone6661]

I recently owned a Siemens-Schuckert carbon arc spot from around 1911 It is in a beautiful state of preservation and I'm curious whether it would still work.

[@Robert.R.83]

The fresnel lense really helps

[@RobWatt]

Rodrigo Prieto ducking for cover is hilarious. That guy always has the best attitude.

[@srfurley]

Is that a Mole Richardson? Haven’t seen one in use for probably about 25 years. I think the last rime was at St. Pancras station in London before it was converted for Eurostar. Can’t remember what the production was but they were using several of them, and one of the operators let me strike the arc. Great lamps, pity it all seems to be HMIs these days.

[@tomkent4656]

I'd be worried that the fumes are not being vented.

[@sailormann1]

Great demo, sir! Thanks for this video. Good question by the guy how long does it take to warm up. Carbons are instant warm, vs. HMI lamps take a little bit to warm up and get to color temperature. Definitely more cool mechanically than a 12K HMI. haha! I wonder if the light quality is better with this brute arc than with a 12 or 18K HMI?

[@kens97sto171]

@@TheFalseShepphard Think about it they had a light source that had pure daylight color from the 1870s. How long did it take us to get back to that point? With high output halogens and HIDs and LEDs? The main issue with Arc lamps is the heat and also power consumption. But they are a superior form and color of light. And when you're talking about film and photography you generally need a hell of a lot more light than the human eye needs to have it come out right on film. Of course all of this has changed relatively recently.

[@TempoDrift1480]

I didn't hear what he said but what is the spin-a-ma-thing on the back? Is it a brush to strike an arc?

[@dickJohnsonpeter]

The arc is struck with a lever that just brings the carbon electrodes together them releases them back to the distance they're set at. The wheels are for adjusting the electrodes. You see one spinning because as they burn they get burned away so need to be continuously kept the same distance apart and that's done automatically so they're basically constantly being brought closer together. The positive one burns 3x faster than the negetive as he noted. The wheel you see spinning is probably for the positive one.

[@peterrivney552]

Where do you get your carbon rods from ??? I know someone who has a old search light in there barn...

[@markcorriher4718]

I have some for WW2 light.

[@GereDJ2]

Ohms law: I x E = P, or power, measured in watts, or power dissipated. So, 9,180 watts? Wow! Is that correct?

[@isettech]

Voltage on the arc after the ballast resistor is typically about 25 Volts. 125 Amps at 24 volts is about 3KW of light and heat from the arc. Movie projectors for the big screen typically ran 60 Amps. Searchlights would run close to 180 Amps.

There is actually a thing, carbon arc gouging... the only difference is a jet of compressed air to blow away the slag/metal. You can buy carbon electrodes at the welding store. ICWeld channel is the king of this.

[@ypaulbrown]

@@scowell there is also CAW Carbon Arc Welding.....CAC carbon arc cutting is very loud, but it will cut any metal that will conduct electricity...it was invented to cut armor plate on ships in WWII

[@ypaulbrown]

@@scowell the [CAC] Carbon Arc Cutting process needs about 35 volts or more to run properly...so not all welding machines can CAC. they are a blast to use though, they throw molten metal 35 or 50 feet away......a standard Constant Current machine which is used for Plasma welding, shielded metal arc welding and gas tungsten arc welding along with submerged arc welding is used, A constant voltage machine used for gas metal arc welding [mig] is not used.you can CAC with AC or DC Constant Current Machines.

16 volts 135 amps? isn't that only 2kW? A 2kW tungsten couldn't compete with daylight like this; are carbon arcs super efficient or something? What's the wattage on this thing?

ALI6359 why would they do that? Isn't it being run from a DC generator? Such a generator produces no DC component.

[@timdelatorre]

I can't remember exactly but I believe their building didn't have DC, so I think they're running it through an older transformer of some kind.

[@KillerJoeFIN]

Its use DC. He said his rectifier is old so it makes this noise. I think transformer before rectifier makes this noise.

[@ShokaLion]

"This is being fed with AC which is three phase... 68 volts 135 amps."
