For those who do not know, that bulb is fine, the black "sooting" on the inside is supposed to be there, it is actually the reason the bulb is called a METAL-Halide lamp. The black stuff is the condensed metal (Hg, Na, Mg, Li, etc.. depending on colour temp [K]) It is not visible when the lamp is new because the metals have not yet been vaporized and condensed onto the walls. This is why the pressure is so damn high (the metal boils!) And is why these bulbs take a bit to reach proper color and intensity, the metals must be boiled off the walls to pressurize the bulb volume, and the more pressure the more electrons hit gas atoms, therefore more light, with more electrical resistance more work is done on the gas (more heat)
@@Flyingsidekickr most if not all Street lights are far smaller and therefore reach operating conditions in about 10s, and here in Canada at least, are being replaced with LED lamps that output full power almost instantly. Could you clarify what you mean by that? (For evacuating traffic)
@@Flurocent77 yeah, true. This is the reason why I use xenon arc lamps with a colour correction plate or cylinder. I've been building Wilson cloud chambers for scientific displays, needs very bright white light, but also must be safe... so no metal-halide lamps. I can't stand these things, the colour sucks, and when (not if) they burst they destroy the housing and reflector. I've been using automotive xenon HID lamps, they are crazy bright for their size, and if they fail, they just leak xenon.. instead of exploding with 2900 psi worth of hot metal vapor.
One thing you are missing here---this is a quartz arc tube with NO outer glass bulb like most MH lamps use, and because of this, it produces LOTS of short wave UV (ultraviolet) radiation, because of the mercury content of the arc---the mercury lines are always there, even after the halide salts vaporize and the lamp comes up to full color and output. This lamp is designed to be used in a glass-enclosed fixture to filter out the nasty UV radiation, which can cause really nasty sunburns in a very short time, and cause serious eye damage. Running this lamp open must have emitted a very strong odor of ozone---caused by the UV in the shorter wavelengths converting the oxygen in the air into O3---ozone. The odor of ozone is a dead giveaway that the lamp's bulb transmits dangerous shortwave UV, and means "shut it off before it burns your skin and eyes"! I would NEVER run this thing open. Also, because the operating pressure is quite high, and a failure would be dangerous, this lamp should never be used exposed! You can see the arc tube gets orange-hot during operation, and this stage is where arc tube failure is most likely. These lamps probably have a very short rated life, and are burning position restricted, although I do believe it IS horizontal, so it was burned in the correct position. The motor as a ballast is clever, works fine, but running this lamp outside it's proper operating current range, etc, on a makeshift ballast can increase the chances of violent failure a great deal. Lastly, as a light bulb collector, I really resent your throwing it and breaking it---I would LOVE to have that bulb in my collection! What a waste of a beautiful lamp! These things are nearly 2 thousand dollars new, and over 1000 dollars used but working, even blackened. A sad end to a gorgeous lamp. I'm not a huge GE fan, but would LOVE to have one of these lamps in my collection! Rick "C-6" Delair, Edison Tech Center, Sechenectady, NY. USA.
Hi Rick. I love your detailed comment. These tubes are dangerous. I'm so glad nothing bad happened this time. My heart stopped when I saw him handling this beauty without a visor. Even with a visor this tube is very dangerous.
+ricksbulbs The way metal halide bulbs work is when the halides vaporize they start absorbing energy from the excited mercury atoms, meaning that less mercury atoms will lose their energy via emitting a photon. This means that when the metal halide salts come into play, not only does the light output from the halides increase, but the light output from the mercury actually decreases. Running a mercury arc lamp of the same power level is far more dangerous than the metal halide equivalent. Though the UV hazard is decreased when using metal halide, it is not nonexistent. As for it blowing up, I don't know how they don't blow up. Glowing orange means that it is very close to melting, and I'm surprised that it is even possible for these bulbs to be made to not explode at 200bar. It would seem a major feat of engineering to get cold quartz to withstand that much pressure, but when it's weakened from being near its melting point, it would seem impossible to keep it from exploding under these pressure levels.
You know what occurred to me when he was illuminating his shed at night? There is absolutely no reason why that beam directed towards the sky wouldn't be visible from space! My man, you should get a ham license (if you don't already have one) or get an accomplice who does, to make contact with the ISS as it passes overhead and get a combo audio/video recording of them confirming that they can see it! We'll be waiting!! :)
Unfortunately not, quick back of the envelope calculation using the inverse square law for light and A LOT of assumptions. We assume the original output is about 1000000 lumen, measured at a distance of 15 meters. This means that at 400 km (orbital height of the ISS) the measured intensity of light would be around 0.001410 lumen, so it *might* be able to be seen, however chances are that unless the test is done far, far away from other sources of light it would get masked out by all the other light sources around it. Now, doing it the other way around, ie. putting a few of these bulbs on the IIS would be interesting. Do it for April 1st and be all like "OMG ALIENS ARE COMMING!"
Glad u uploaded this one, those lamps are ridiculously bright and we have a few 12KW halide lamps with a ceramic coat on the arc tube to keep more heat in and an outer envelope to stop dissipation during heat up
Great video, love the newly edited footage. Unbelievable that the glass can handle 200 bar pressure and not even pop while hot and under that high pressure. Great use of those motor interpoles.
did you get a light burn from that light? I used to work with a machine that used a 500w halide and everyday i got a red tan on parts of my face that werent covered. i learned quick not to stand next to it while it was running the exposures. lol
Love your channel PI ....... do you ever see indication on your electric bill after certain experiments? What is that main control panel thingy you use ? Where did it come from?
Just read the linked document in the video description. The plasma in this metal halide arc lamp reaches a temperature of about 10000 degrees C. If you remember in your science books, 10000 degrees F is the temperature of the surface of the sun, but 10000 degrees C is 18032 degrees F. This is almost twice the temperature of the surface of the sun! When running, pressure rises to 200bar, which means 200 times atmospheric pressure! I'm surprised that these things are even able to run at all without blowing up. Sounds like a way to make a plasma grenade from the Halo games, if the bulb were to fail while running at full power.
Except you can't throw it and it doesn't stick, but besides that it'd basically be a grenade. Oh, and one atm is 1.01325 bar, so it'd be like 197.17 atm.
Howling Wolven 1 ATM is approximately 1 BAR. As such, 200times atmospheric pressure is a good approximation. Do you really think an explosion at 200 ATM is stignificantly stronger than an Explosion at 197.17ATM?
12 k is the biggest HMI that I've seen running, but 18 k have been available for a long time, and Mole Richardson now make a fresnel fixture which takes a 24k lamp. There's a video of it on TH-cam, but not running unfortunately.
Aside from just the luminous intensity, the ultraviolet radiation is also probably very high and potentially hazardous. This was a problem back in the 1880s and early arc lighting. Fused quartz doesn't block UV very much. The full fixture for it probably has UV filtering.
Loving the vids! I dont mean to be intrusive or nosey but may i ask where you gained your broad knownledge of all things electrical? From watching your videos, I feel you know more about electronics than my college tutor, whom is currently teaching me electrical engineering.
+Engineering Nonsense Yes, because he installed a huge light on his house to light the street when the city turns the lights off. www.kentonline.co.uk/gravesend/news/engineer-andys-bright-idea-to-15218/
I should do the same. The city and electric company are too lazy to change the streetlamps where I live. Now they are all burned out, except for lights mounted on houses and buildings.
Yes hello I would like to know about this discharge source? Is this source hotter than halogen lamps??? How many Watts does that make? What can it do and how many volts can it do? Is there a mesh around the metal glass like the xenoarc bulbs? Is there mercury or not? In which light fixture can we use this source, is this source still in production???
Two questions. Is the Reactor Live light just for show or do you actually have a Reactor? I wouldn't be surprised if you did XD. And, Where did you get that lamp?
Best explaination of how a tungsten halide light works I have seen. So as I understand it from this vid the iodine recombines with the dark tungsten sputter and reforms it to blobs which drop off the glass and clear the bulb? Must have read it in books 100 times and still didn't get it till now :D
Im pretty sure they're setup to detect a double flash, which is a product of the shockwave temporarily dimming the intense light, as it gets out of the way.
Oh man. My heart stopped for a moment. I'm working with 1200W MHD lamps myself, and I never handle them without my XL visor. Keep in mind, these lamps are under an extreme pressure. I have seen the damage caused by a broken 575W-lamps. Believe me, you don't want the 12kw lamp to wreck next to your face, even not with a visor.
+Robert Fitzgerald Nobody in their right mind would do that, without having it in a large (to accommodate the expanding gas from the explosion) fully enclosed room sealed off room, with walls at least 1 foot thick, made of a mesh of re-bar with concrete, with a remote button to a robot arm to drop a rock on it. At 200bar (about 3000psi) of pressure, lets see how much force is exerted on the glass. Assuming it's a sphere (which it isn't, but should give you rough idea here) of about 1.5 inch radius (sounds about right for the size of the bulb here, going by its visual appearance) you have a surface area of 1.5^2 * 4 * 3.14 = about 28 square inches. At 3000 pounds per square inch, that is 84000 pounds (42 tons) of force pushing outward on the glass bulb from the inside! Assuming a typical family car probably weights about 2 tons, the force pushing outward on that bulb is approximately equal to the weight of 21 cars! The force of the blast, should this bulb break, would be at the level of a good sized pipe bomb (like the ones seen in terrorist propaganda footage of the Iraq war that show the blast launching a HumVee 20 feet up into the air)!
They say that one of the most infamous symptoms of mercury exposure is madness. Well, Mr. Photon, well... :) In all seriousness though, I do agree that the (recent) hype regarding mercury dangerousness is far exaggerated.
With fewer of them will they be a signal for drones at critical evacuation points as with the purple defective streetlights or just greenish LED streetlights?
I can't imagine an application that would need that much light except maybe a helicopter spot light. It might be pretty cool to put one of those on the space station. hehe
Dumb question here, but what is it about the way he is powering it that wears it out so quickly? I imagine when used in a proper fixture they last many times longer, but what is the difference?
Interesting that it didn't explode cold. I thought it would, but I do know that the most dangerous time to change xenon lamps in a follow-spot or projector is when they're hot. Which is coincidentally right when you desperately need to put a new one in. A work colleague had one explode in his face without protection. Fortunately his eyes were OK.
yikes
That's actually not the first time I've heard of something like that happening. Odd.
To clarify it was with halogen two of these times and some other HID lamp the other time.

They say that one of the most infamous symptoms of mercury exposure is madness. Well, Mr. Photon, well... :) In all seriousness though, I do agree that the (recent) hype regarding mercury dangerousness is far exaggerated.
With fewer of them will they be a signal for drones at critical evacuation points as with the purple defective streetlights or just greenish LED streetlights?
if you focus the beam and shine it at the moon....
What if you ran it underwater in the fish tank? I wonder how long it would take to boil...
Where do you get Halide Lamps that size?
I can't imagine an application that would need that much light except maybe a helicopter spot light. It might be pretty cool to put one of those on the space station. hehe
as a lamp in lighthouses i imagine
That lamp and the mirror aimed up would no doubt have been seen from the ISS if pointed at them, im not even kidding.
Dumb question here, but what is it about the way he is powering it that wears it out so quickly? I imagine when used in a proper fixture they last many times longer, but what is the difference?
Probably cus' the power he dumps in to it is a lot 'dirtier' than what you'd see with a proper purpose-designed power supply.
