The irony is.... A Japanese bloke took the picture! Maybe I should ask him to find out who sells them in Japan!

pretty large jacket for such a "small" burner - maybe they designed the lamp in such a way that its envelloped does not reach a too high temperature so as to better withstand the weather exposure...

I was speaking when he snapped the shutter, that is why I have such a "grimmace" on my face!

There is quite a story behind this photo. I am an electronics tech, and nearby there is an engineering business run by a bloke with a boinic arm. He has about three expeiremental arms he is designing and had me working on one. I had finished it and had gone out the gate carrying it (to take it back to him). Just outside the gate I an into this Japanese bloke, about my age with a Leica camera and he stopped me to ask me if he could photograph the house.
It turns out he was a Reuters professional photographer, had lived here in Hobart for over ten years and was married to a local.
I saw the chance the make lamp collecting connections in Japan, to get lamps like Colin's dual arc Iwasaki or James' 100v self ballasted mercury. So I got talking to him and the subject was "steered" around to lamps. He asked me if he could photograph me with some lamps to which I agreed. He sat me in the back yard and, ironically, this lamp was still out of the container (amongst others) because it had been used when the little film, "The Globe Collector" had been made a few months earlier by Summer De Roche and it was a uniquely Japanese lamp. So there it is, me, looking typically ugly, in the back yard with this lamp!
P.S. Anybody ever had any contact with Japanese collector, Shugeki Oshima? He could open doors wide to the acqusition of such lamps for all of us!

Now that is a valid point "toomanybulbs"! I'm not sure of the internal conditions of this lamp. It has no starting electrode so its outer bulb may well be a vacuum. Some are nitrogen filled to about 500 torr.
Yes, I might need to use a Tesla Coil or do a thermal conductivity test on this....

This is a beautiful lamp Globe Collector , Ive seen these in use , hanging in "open" festoons. I assume they are hard glass to withstand the open use / water splashing , etc. Also , do You know how they operate these? Are they run in series in those strings? - I was unable to get a good look at them up close when I saw them , but there was no evidence of any control gear close to the lamps - just the bare lamps hanging in strings.

Also , I am curious to know more about Shugeki Oshima? , and You mentioned Japanese connections . As I think You know , my Ladyfriend is from Tokyo , and currently lives in Tokyo (She lived and worked here in UK some years ago). She is a great source of Japanese lamps and is always sending me and getting lamps for me and its possible She could e-mail / find this Japanese collector. (She has been on several Japanese lamp websites for me).


Maybe You could PM me , either on here or on ATL sometime

I think it could have been made by Koto. Although they don't list such types, in one of their 1980s catalogues for the export market there are various photos of the factory, one of which shows the process of sealing the outer bulbs of similarly large metal halide lamp whose shape of bulb is quite unusual, and same as your photo.

Mention of the short film 'The Globe Collector', SBS is screening it here this week (4:50am Friday). The printed TV guide seems to know more than the Smart TV which for some reason can't seem to list the programs that far ahead. Must remember to set the recorder.

AGAIN! This would have to be about the sixth time, but who'll be watching at ten to five in the morning...know I won't, you'd need an electric cattle-prod to move me at that time!
If you miss it I can bootleg you a copy anyhow! It ain't so much about the globes, its more about me...not that interesting really.
Socketgeek, I have another 25 of these (of a different brand though, Koto MF 201's, in the container, all used though. Want One?
Do you think it would get across the Duck Pond in one piece?

Jeremy, just seen your question, sorry the answer was so long in coming. I don't think they are strung in series, I think they are run from an alternator with some sort of wide gap between the rotor and stator to get the output impedance up, but still not sure how they run more than there (one on each phase to give an even torque in the shaft of the alternator. I reckon multiple stators stacked around one rotor.

I have lots of Japanese lamps I'd like the kanji translated off of and I'd love to "close circuit" with Sugeki Oshima!

I have not seen this film. I only noticed it in the printed guide because it had the prefix MOVIE in red text (I was looking to see if there were any decent movies worth watching/recording during the forthcoming week).

It would have been a hell of a lot better, Michael if Tropfest hadn't stipulated Summer cut it back to seven minutes and left so much of it on the cutting room floor at Break-O-Day films in Brunswick!
Socketgeek....depends upon if they charge on volume or mass. Within Australia, Australia Post have this potty sliding scale based on both mass and volume, but if it is leaving Australia's borders, it based only on mass so the box ac be as big as you like!

Glad you got it all back together Callum. Was the lamp expensive? I would not pay more than $15 for it.

I do intend to light a similar one to this one day. (Sadly this one has a fractured lead-in just on the outside of the press. up inside the stem where the brittle nickel-iron seal wire has broken right at the glass). I now have some Koto MF-201's which are very similar and fully functional.

The trick here is that this is 2Kw and has an arc drop of about 105v, that is damn near 20A and a standard powerpoint/GPO will get a bit stressed by this hefty current with its huge out of phase component.

I have an idea though where I think I can create a continuously adjustable power factor correction device which will allow me to manually maintain the current in the 8-10A range, particularly just after the lamp has started and its arc voltage is low, c25v.

Lets assume you can get it to full power in an instant, it will have a current vector lagging by around 45* consisting of roughly 10A of in phase current (for the lamp) and another similar amount of quadrature [90* lagging] current from the choke, the vector sum of these (done on a right angled triangle using Pythagoras' Theorem) gives about 14A all up. If you dump a capacitor in parallel with the whole caboodle, there will be a loud BANG as you connect it and it would need to be quite large, 132uF having a capacitive reactance of 24 Ohms, thus would allow all the out of phase current to simply circle around through the lamp, choke and this capacitor and thus only the in-phase component, about 8-9A would be needed from the mains to "pump" it.

But what of the lamp just struck....its arc voltage is so low it almost may well not be there at all, just like connecting the big choke directly across the mains, a thumpn' 27mH of it, a few turns of THICK wire through a HUGE core! To get rid of that sort of quadrature current will take a bigger capacitor in parallel, something big enough to bring it into parallel resonance at 50Hz where the impedance of the combo will go nice and high, this means the inductive reactance of the choke must equal the capacitive reactance of the parallel connected capacitor so this huge current will simply circulate between them and hardly any will be drawn from the mains. 27mH has a reactance of about 8.5 "Ohms" and to get the same from a capacitor requires a thumpn' 368uF worth! There will be 28A circulating between them but almost nothing coming from the mains! Now as the lamp comes up, it appears as a resistance in series with the choke, decreasing this huge circulating current and gradually decreasing the voltage drop across the choke as the voltage drop across it increases. As all this is happening the value of the capacitor will need to be decreased from the huge 368uF gradually down to the 132uF required when it is fully up. I could shed capacitors from a bank and do it in steps, whilst watching an ammeter and trying to keep it at a minimum, but I din't like disconnecting capacitors whilst it is on...so I could connect the HUGE capacitor to the wiper of a variac connected in the circuit where the capacitor would normally be and simply gradually turn the variac down to make the circuit see a gradually diminishing capacitance, but the variac would cop the 28A at the start and the biggest variac I have only handles about 8A. So I need a second variac to adjust the voltage to the whole lot, this will be turned down low, c60-80v as soon as the lamp strikes but no so far as to extinguish the arc, then it will be tracked up as the arc voltage rises and the capacitor variac tracked down...all while maintaining a minimum of current on the ammeter...when the lamp is up, it will be getting its 110v at 18A, whilst the mains will only see 8-9A at 240v.

I think I will do it small scale first though! With a 400w mercury lamp maybe.

Lamp only cost about 8 bucks from middendorps. Funny thing L&H wanted about 15 for the same thing!
I see what you mean about powering it tho, you need the high amperage with low voltage in order to get a steady flow.
YouTube user Photonicinduction managed to run a 12KW metal halide lamp by using a big electric motor stator in series, as a magnetic ballast, then a big cap as an igniter to get the arc started. It was a very impressive set up. Except for the amount of shortwave UV it would have given off!

Now THAT is one BIG glass balloon!Would love to see this lit.Guess lighting that lamp is a challenge due to the 2Kw-in the US the ballast would have to run from 200-240V on up.This would be even too much to run from a 120V 20A circuit.GE made a double end 2.2Kw PSMH lamp for stadium use.These fixtures ran from 240V-480V only.Never seen one of those in the real-just have a flyer about it somewhere.The 12Kw MH lamps were often and most commonly used for TV and studio lighting.Ran from VERY large 240V ballasts.The ballast was mounted separately from the lamp so its hum wouldn't be picked up on on set microphones.For TV lighting-at least in the analog days-the ballasts ran from an AC supply synced to the studio syncgenerator system so hum bars wouldn't get into the picture.These sort of lamps replaced carbon arcs.Have a Mole Richardson catalog showing these.Not only the UV from these is a hazard-but the lamp could have ruptured with GREAT force from the Photoinduction "Improvised" ballast.Did see the video.That light lit up the whole neighborhood he was in!!The neighbors probably thought for sure he brought the sun in!Remember he ran the bulb unenclosed.In actual use these are always run in enclosed lighting instruments as the stage lighting folks call them.In set lighting those 15Kw lamps were also used for "sun fill in" in outdoor sets and the lamps and ballasts run from heavily soundproofed gensets.

I will let the catalogues of two different manufacturers of lamps for the same purpose answer this question.

You will need a .pdf reader to view them, you can download it from the net if you don't have it.

I would LOVE to get a 9,000W Underwater metal halide lamp from that Koto catalogue! Even a boat-deck 4,000W lamp would dwarf this lamp, at 6cm larger diameter and almost 15cm longer! The trick is of course how to order one of these beasts?

Interested mainly in discharge lighting (mercury, sodium, neon) and also old and unusual incandescents.

pretty large jacket for such a "small" burner - maybe they designed the lamp in such a way that its envelloped does not reach a too high temperature so as to better withstand the weather exposure...

I think it's for filter most of the UV like Powergrooves

There is an Incandescent Version Daniel.....3Kw 180v and I have more than one of them!

Manufactured articles should be made to be used, not made to be sold!

Awesome !! At the moment I had to give up an osram nitra 3000w. The seller did not want to send me to Spain. the problem is that in Spain there are hardly any incandescent giants. in germany they sometimes tell me they don't send them to me .... today I already have the dream come true !! Everything you get today will be extra. when you upload photos of the 3kw incandescent let me know please see. Greetings

You know what an Aussie (Australian) would do?

Jump in the Ute and drive to Germany, (from Santiago de Compostela) and get the Nitra in person..it's only 1000Km, (2000Km round trip).

I have a friend who drives from Finely in New South Wales to here in Hobart about once every two months....that's about the same distance from Santiago de Compostela to Marsailles in France.

I had one chap drive from Perth to Hobart to deliver some lamps to me, (and visit some family members here...so do more than just one thing) ...that's about from Santiago de Compostela to Warsaw.
