My uncle ran (and I believe still does run) a searchlight company here in Canada called Skysearch. He bought a few surplus WWII carbon rod arc discharge searchlights that run at, if I remember correctly, 100 million candlepower? Something insane like that. My dad worked for him, hauling and running the searchlight to events, and as a kid I would tag along. They were unbelievably cool. They had a huge diesel generator for power, but they also had the automatic rotation feature. They also had the ability to connect to a remote control at an anti-aircraft gun, and they would use (I'm assuming) something like synchro resolver and some basic analog computing to triangulate 2-4 of the searchlights wherever the gun was pointing. They also had the ability to run with the generator a fair distance away. They knew the bombers would target the lights, so that's why the remote control was important. I remember the cable connections used to connect to the remote controller (which unfortunately I don't think my uncle had any of) was absolutely massive and had a ton of pins on it. One of those huge military spec connectors. When I was a teen and moved in with my dad, he would take me with him after school sometimes to run searchlights. Then I would wear the same t-shirt the next day and smell like searchlights (a mix of diesel exhaust and carbon dust and stuff). I always thought it was so cool. Now that I'm older and understand how the circuits likely worked, I find them even more amazing.
As a kid, those World War II search lights repurposed into event promotion sky lights fascinated me. My Dad would track them down so I could see them up close. I didn't find out until I was way older that the flame was part of the arc itself - I thought arc lights were always glass-enveloped devices. Turns out those things were basically glorified arc welders!
@@russellhamner4898 Yup! The most finicky part of those old searchlights was the feed mechanism. As the carbon rod got eroded, the searchlight would feed the rod inward. The way it actually worked is it would measure the voltage across the arc (the further the rod is away from the anode, the higher the voltage) and it would maintain that voltage by moving the rod as needed. It was a neat idea, but I remember my dad having trouble some nights with the auto-feed. It would sometimes feed too fast, and the arc would get really dim, or other times it wouldn't feed enough, and either the arc would extinguish, or, in the worst case, it would jump from the anode to some other piece of metalwork! The searchlights had a safety system if this happened, but even the half-second it took for the system to kick in could be long enough for something to get melted. Another thing I remember is that the searchlight could be locked in the vertical position (facing parallel to the ground) and the glass front slides open. My dad would have to get in there before we fired them up and clean the entire reflector and glass with Windex and a towel. Despite cleaning them before every run, the reflector in particular was always filthy because of the carbon rod being vaporized and then just depositing on whatever nearby surfaces. You could really tell the difference in the brightness between a clean and dirty reflector. Now that I'm an EE (working in digital stuff) mostly) I really should go visit my uncle and see if he'll let me reverse engineer some of the circuitry. If you have any more questions about the searchlights, let me know. I know way too much about them.
If you're curious to learn more about searchlights and how they work, check out my other comments on here. My uncle ran a searchlight rental company, and my dad would take me along whenever he would go to an event to run them.
Oh wow, that high voltage arc only has to run for a minisecond to strike the arc! For some reason, possibly because I'm very stupid, I thought it would have to run for minutes before the regular power supply to take over. Feel the POWAH!
Dude seriously, WELL DONE! I truly appreciate the explanation. You definitely bridged a few gaps in my mind. I studied chemistry but began learning electronics after school. I constantly refer back to my notes now a days when I need to freshen up on the equations and it makes more sense than ever before. It’s amazing. Thanks in part to videos like this. Good luck with your future studies!
I have Ben flagged as the most awesome dude on the tube, I love the dry unassuming attitude of this genius at work. Always inspirational. Thanks for posting
Hi Ben, I am learning--From what you said, my 'gut' tells me you should put the original coil back in, and add a fan. Thanks for all the great HANDS-ON learning videos!
Reminds me of those lights they'll put outside during some big event, I always associate it with movie theatre events myself, they shine those bright spotlights like this up in the air and wave them back and forth, so you can see the waving beams of light from miles away.
@@carolynmmitchell2240 but, back in the day. Photonicinduction use halogen lamp and not focused, while this is xenon short arc and all the beam focused into one spot. Photonicinduction does have bigger xenon short arc rated at 4kW and 30kW. But, he didn't put it on reflector. The one and only arc lamp photonicinduction run it using reflector is 12kW metal halide lamp, and some arc lamp using red protective cover (i don't really remember the type and it's rated power).
Such a great project and then only a parabolic "mirror" a little shinier than the housing itself. I guess, using a really smooth mirror would make this thing insane.
Forgot to mention, I too once wired a TRIAC dimmer to an ignition coil with the spark gap between thick gauge copper wire and a spark plug and boy oh boy, do I remember those corona discharges jumping over the insulation at the coils terminals! Very loud too.
LOL! Thanks for the idea of using trashcan as searchlight housing. You can easily polish inner surface with car polish stuff to make it really shiny and reflective.
Your device quite interesting. A way to inject the HV pulse, is to capacitively couple in the pulse through the lamp wall, glass body. Doubtless this is fused quartz. (no finger prints please). This is a standard laser lamp ignition method. A floating small dia trigger wire is wound around the lamp envelope for example. Must be near the cathode and anode of the lamp. Yes, isolation of the HV pulse is very important, to prevent failure of the lamp LV supply. A common mode choke on the LV feed pair will help keep ignition pulse out of the LV supply. All should be located near the lamp can, as you have done. Nice work!
yes and now, laser tubes are low pressure, this Xenon short arch lights are high pressure. They have at cold state around 6-8bar gas pressure, when hot around 50-80bar !! Therefore the ignition pulse is best injected via the electrodes.
I recently scored a couple 5 kW Xenon lamps. Cant wait to get them started. The problem being that they are water cooled (around 4 L a minute) and I need to make some nonstandard connectors.
Hey there I had a question for you: I have an old 35mm theater projector that uses these lamps. It’s a complete unit including the lamphouse. My question is can you hook up the DC power coming from the inverter arc welder directly to the rectifier in the lamphouse? The input for the lamphouse power is 3 phase 220v ac, which I don’t have access to. I figured I would use the benefits of the existing circuitry but was unsure if I could plug dc power from the arc welder directly into the rectifier. In theory it makes sense in theory but I am searching around and couldn’t find anything about if it was safe and would work. Thanks!
Hey Ben, I have a large collection of these Arc lamps from a few hundred watts to 7kW. I have watched this and the other video countless times but am struggling with the ignition circuit. Would you be able to lend some suggestions? I can't seem to get the voltage on the other side of the toroidal ferrite.
BEN!! (right?) At about timestamp 5:55 you mention H.V. level compressors. What about one of those High Power lightning arrestors used here? They seen to be cheap, reliable, and effective, in this type of surge suppression--even the smaller, inexpensive types. I think I remember they can also be used in series for higher voltage protection. I just bought about 300 of them from All-Electronics, or Mouser for a dirt cheap price. I cracked a couple open and did not like the dirty-looking 'screening' inside! But still, you could see the bluish-purple (magenta) light through the ceramic cylinder.
Is there a way to get in touch with you? I have an old movie theater projector with a xenon console I want to resurrect today and I am using an arc welder inverter for the power supply coupled with the igniter already in the console. I need to know if I should hook up the output of the arc welder inverter to only the lamp, thanks!
Where did you learn how to do all this? You do a bunch of projects involving electronics, chemistry, woodworking, and even cooking. Did you teach yourself? I love this channel!
Hey again Ben, Is that starting switch a momentary push-button or a toggle (SPST) type switch? It appears to switch the SCR through a capacitor or a resistor to the primary coil of the ignition coil. Thanks again, ...really trying to learn this circuit--a schematic would be GREAT!
Sorry by insistence, i can see in this video an oscillator attached on this start coil. Is that true? I´m thirsty for this schemmatic, about this search light
Tanks for the information, but, could i use common rectifiers, such bridge rectifiers about 30 amps to drive this bulb? Something like that i´ll do with flash xenon bulbs, which have three electrodes. What diodes have you used for this?
@5lkk True. I feel kind of iffy around both on their own though hehe. I prefer to stick to logic level signals. At least they don't hurt when you mess up ;)
@bkraz333 All iron powder torroids I've seen are yellow. Also if it was an output choke, it has to be iron powder. Another giveaway is it heating up. Iron powder cores have high loss, but are cheaper than gapped ferrite.
hi Ben, can you tell me what is it between ignition coil and white capacitor? it's a diode or a resistor? and can you tell me capacity and voltage of blocking capacitor?
That old inductor is wound with litz wire - Lots of tiny insulated wires- The reason it's getting so hot with that regular wire is the skin effect. It's a high frequency thing. Wikipedia it. Litz wire. And I quote "Litz wire is used to make inductors and transformers, especially for high frequency applications where the skin effect is more pronounced and proximity effect can be an even more severe problem. Litz wire is one kind of stranded wire, but, in this case, the reason for its use is not the usual one of avoiding complete wire breakage due to material fatigue. Litz wire is frequently found in power applications in frequencies ranging between lower tens to higher hundreds kilohertz, namely induction cookers and transmitters of inductive chargers (e.g. the Qi standard). Multiple parallel twisted strands of enameled wires can be found also in transformers in some switching power supplies."
This is _sick_. I bow to your mad hacking skills. Very nice! (I also kinda have a light source fetish, so a DIY Xe arc searchlight is extra badass in my worldview).
Try getting an IKEA 14 inch stainless steel serving bowl. They are like $12 and I have tested one with my 1000 watt HPS light and there is a solid beam emitted
I really like this pulsar starting circuit. I am familiar with the components and how they work--Is there any chance of showing a labeled schematic: With component values--especially the HV doorknob capacitors (C & V), from the input of the welding (input) wires to the lamp driver? THANKS MUCH, --dALE
Just a suggestion : instead a single thread solid wire, try multithread wires like there is on the original toroidal transformer. The reason is skin effect which increase with frequency. The magnetic field force the electrons away from the center on the wires, so the most efficient design woould be hjollow wires. The second best option is a lot a small wires not in parallel but crossing each other is different way... exactly like the wires on the original transformer..
Hi Sir, I have just purchase a Philips 1000 Watt Xenon lamp which I wish to use in my Christie 35mm Film projector (I have converted Christie Projector to a portable machine to run at home just as a hobby). I have also purchased a DC welder. Could you please send the SCHEMATIC CIRCUIT of your ignition system? Thanks
too bad I saw this 10 years late... 30 years ago, laser, xenon and carbon arch lights where one of my specialities. To stricke a bulb cold, you would want to apply a 2-4kW electric field over the electrodes, to excite the gas molecules, before striking and 10-20kW arch across. Striking the gas directly is quiet difficult, because this bulbs are Xenon Short Arch - High Pressure bulbs. The high pressure means several atmospheres of gas pressure even when cold ! Hence you need to excite the gas first, else the energy required to build the plasma arch is very high !. A word of caution - this bulbs are very dangerous, as they build up to 80 bar pressure when hot and have a tendency to burst spontaneously, specially if there is not enough cooling or finger prints on the glass. I have seen them burst several times, it sounds like a very close gun shot and leafs nothing but quartz powder (plus electrodes) behind. The explosion can be so strong, that it will be heard over the sound level over a live concert in a arena with ease (been there, done that) !! So careful with the beautiful bulbs :)
You have 50 amps running through that 8(?) gauge, insulated, non-fiberglass, non-fluoropolymer insulated wire???! Any electrician would give you wrist slap. Fire waiting to happen. But, this is certainly a special circumstance. I’d do the same.
I was the purchasing agent and general manager of a company that serviced the work boat industry on the inland waterways, and we sold and serviced Carlise & Finch searchlights. There was also a brand called Varo, but they were not very reliable. The wire used in these was teflon insulated, and then covered with fiberglass braid within the housing. When I started, they were all carbon arc, finicky, and dirty. Next came 2.5KW xenon, followed by 1KW. We sold a lot of xenon lamps, and they are dangerous. You are so right MisterLepton.
please be extremely careful with this lamp! They radiate a lot of UV radiation and are under extreme high pressure! You should use a thicker housing an protecting glass for the front

I like this a lot. As a kid I remember being enamored with the huge rotating spotlights used to promote events at night.

Ben's videos feel a bit like Kerbal Space Program, but with no explosions :)
Colin Furze on the other hand is like a kerbal space program but with epic explosions. Not as sciencey tho.
YES. :D
I am going to watch every single video you have produced. 50 AMP custom power supply! Insane!
R Bain Lol, I'm sure you were in for a treat if you thought this was insane.
You my good sir are a mad man.... And I admire that!!!
I love the pillar of light at the end!
What if you put lenses in front of that, can you get a burning deathray?
So.. If I ever visit the bay area and see a huge tower of light like that at night, I can be confident it's you?

Great work. Have you calculated the produced lumens and the lm/watt efficiency? Also, why did you not show the actual lamp at all?
Nikolaos Skordilis He did show the lamp at 6:02 , the actual powered-lamp would likely have damaged the camera sensor permanently

can you please post the detailed power circuit diagram
I wonder if a stainless steel salad bowl would work as a better reflector? Polished, of course.
What is the white piece connected to the dimmer?
Just a suggestion : instead a single thread solid wire, try multithread wires like there is on the original toroidal transformer.
The reason is skin effect which increase with frequency. The magnetic field force the electrons away from the center on the wires, so the most efficient design woould be hjollow wires. The second best option is a lot a small wires not in parallel but crossing each other is different way... exactly like the wires on the original transformer..
Holy crap that's awesome

I think the ferrite induction coil should be insulation free. Ferrite should be able to take high temps.
what about the high voltage
That's whatI call a "Because I can!" video.

could you ignite it with a flyback that is isolated from the ground?
great use of a dustbin (trash can)!!
Calmly states I blew up a welder!!!! Cannot stop laughing.
and how do u put batman logo on it? :d
cut the shape out of metal and have very thin metal arms hold it up in front of the light.
Awesomeness in a trash can
About how many of these bulbs does our government use in the sun simulator?
mount the starting circuit on the back looks better
You need to add a Stainless Steel Trough Mirror (google it) to the inside of your can to increase reflectivity.
Flying apart like leaves xD
I'm surprised that some nervous Nelly didn't cal the cops on you...
