Hello fellow collectors. There does not seem to be a lot of bulb colectors in Canada.
I have been collecting for40 years. But never got seroius until I found Ebay in 1995. And then I found Kilokats I was in My glory.
I have about 200 now, and don't know any more than Tim or some of you other collectors, but I love to display them.
I would like to pass this along about doctor Hugh Hicks collection.
Last night 0n C.B.C. Radio the Baltimore Museum of Industry was interviewed by Paul at C.B.C Radio. They mentioned a 75,000 watt that comerated the 75th anniversy of G.E. IT was never lit and if it was it had to be done in stages. They also have a 50,000 Watt. Best regards Poppa Bill bulbs

Poppa Bill,
Thanks for that update. I was looking for a reference to the 50kW light bulb recently, and found the obituary on Dr. Hugh Hicks.
I saw the 50kW (or is there more than one?) at the Henry Ford Museum in about 1981.
I could not find a reference to it or to the 75kW bulb, so shelved my research for the moment. A pix of either would be great!
Anyone else know about these monster incadecents?
Note to Tim, how do I change the thread title, when posting as a follow up or reply? I'd prefer to reflect that wehave gone off the original thread?
Thanks In Advance!

Hi Peter,
I don?t know of any way for a user to change the thread topic name/title ? I don?t think it?s possible with this forum software. Regarding the monster bulbs, I believe both the 50kw & 75kw bulbs were made in very low numbers by Corning Glass to commemorate Edison?s 50th (50,000 watts) and 75th (75,000 watts) anniversaries of the first successful incandescent lamp. Here?s a picture I took recently of two which inhabit the museum located on the premises of the Edison/Ford Winter Estates in Fort Myers, FL. The 75,000 watter is on the left and the 50,000 watter is on the right:
(http://www.bulbcollector.com/photos/corning.jpg)
So it would appear there are a few of these big lamps around but it is unlikely the average collector would have a shot at obtaining one. Snagging a huge 10,000 watter would be more realistic and they also make impressive additions to a bulb collection!

Hi fellows; try The {Baltimore Museum of industry].And go to Press, That's as far as I searched. Best regards;poppa Bill bulbs.

I have an Spanish book on Electricity that pictures one of these monsters. A such bulb are quoted as "Japan made", 50KW rated and looks like 75 kilowatts on the left of Tim's picture.
Such photograph are underlined (in Spanish) as follows:
"Enorme l?mpara japonesa de incandescencia de 50Kw"
that once translated means:
"Enormous Japanese 50Kw incandescent lamp" and behind it appears a smiling japanese woman holding it on her arms. Really are a big bulb!
Best regards.

Pity. I'm active on a Yahoo group which goes off topic regularly (I'm sure I'm not the only guilty one....) Months later it's quite a chore to find old messages again. Can you ask this software's publisher to comment?

Ahh... Yes! After twenty years I thought I was imagining these! I saw them in the Henry Ford Museum in Fairlane/Dearborn (Nr. Detroit) Michigan, around 1981. Since then I had no success in find any reference to them again.
Here?s a picture I took recently of two which inhabit the museum located on the premises of the Edison/Ford Winter Estates in Fort Myers, FL.
Hmm. Any clue as to whether these are the bulbs from Michigan? Where should I go to see them again? (Sounds like Florida). I know nothing about Fort Meyers, does it compete with the Henry Ford Museum for Edison artefacts?
The 75,000 watter is on the left and the 50,000 watter is on the right:
From memory (again) I recall that one of these bulbs used four pounds of tungsten, and the info card in the museum noted that amount would make (big number forgotten) 60W type A bulbs. Seems like many thousands of bulbs.
So it would appear there are a few of these big lamps around but it is unlikely the average collector would have a shot at obtaining one. Snagging a huge 10,000 watter would be more realistic and they also make impressive additions to a bulb collection!
Oh, yeah? 10kW. Was this a novelty lamp (the tenth year anniversary, perhaps?), or does it have a serious application? Any PIX or URLs to see one?
Comments Welcome!

Hi Peter,
Here?s a picture of a GE Mazda 10kw lamp I picked up a few months ago:
http://www.bulbcollector.com/photos/10kw.jpg (http://www.bulbcollector.com/photos/10kw.jpg)
This is an early design, made before the mogul bi-pin base came into use. The original crate that came with this bulb has a Nela Park label dated 1928. These large bulbs had legitimate uses in the film and stage industry and where high light output was needed ? search lights too perhaps. They were made for many decades in the larger G96 envelope with standard mogul bi-pin bases but even these seem to be a challenge to find now. I?m sure they were low production runs because of the specialized need and application for them. They do surface on eBay every now and then but prices are usually ridiculously high?

As of this instant, there is a 10,000w Mazda lightbulb currently up for auction on eBay. The current bid is $73 and it has 5 hours left.

Yoshi,
Missed it! Well at least I know what to look for in the future. As A.J. Franzman pointed out, the granules in the bulb assist in cleaning to deposits from inside the glass.
I have a 1500W bi-pin base (I'm confused if this is a MOGUL base - a name I thought only went with the larger Edison Screw base), with granules inside - which I mistakenly thought were shed from the filament!
Comments Welcome!

Hi Peter,
There are two versions of the bi-post type base that I'm aware of. ?I refer to them as "medium" and "mogul" although this may not be industry terms for them - can anyone verify? ?Here's a picture of a "medium" bi-post lamp:
http://bulbcollector.com/forum/index.php?topic=432.0
The pins are smaller in diameter than the larger "mogul" size...

Tim,
I believe that the size you are calling "medium" is actually called "mogul bi-post". I seem to recall seeing sockets for this type of bulb base while doing web searches to help Peter find his mogul screw-base sockets. Apparently there is still some demand for these (mogul bi-post) sockets in the motion picture, theatrical and live entertainment industries.
See the bottom of this page: http://www.altmanltg.com/prod_distributionequipment.htm (http://www.altmanltg.com/prod_distributionequipment.htm)
Note the proximity of the mogul bi-post (MOBP) and mogul screw base (MOSB) sockets in the image, which allows scale to be judged fairly easily. Notice also that there is a medium bi-post (MBP) socket in the same image, which appears tiny by comparison - definitely not what you were referring to as "medium".
What that leaves for a designation of 10+KW size bi-post bases or sockets, I haven't any idea!
P.S. There's an engineering drawing of the mogul bi-post socket at http://www.buhl-ind.com/pdfs/Be%20Pdf/be-qcg-38.pdf (http://www.buhl-ind.com/pdfs/Be%20Pdf/be-qcg-38.pdf) but unfortunately dimensions of the holes and spacing between them are not given! Assuming that the drawing is accurately scaled, the center-to-center post spacing appears to be 1.5 inches.

I saw the 50kW (or is there more than one?) at the Henry Ford Museum in about 1981.
The Thomas Edison Depot Museum in Port Huron, Michigan also has a 50,000 watter. This is the train station that Edison went to when he was a young boy. The depot sets next to the Blue Water Bridges that goes to Canada. The museum opened in 2001 and a nice place to visit with it located on the St. Clair River.
http://www.phmuseum.org/depot/depot.htm (http://www.phmuseum.org/depot/depot.htm)
Here is a picture of the bulb in the depot.

Hi everyone
First of all, welcome all the new members. Its really great to know how many people are interested in collecting light bulbs.
Next I hope I can shed some light on mogul bipost and medium bipost bases. We use both in our TV studio lighting. The mogul bipost have 7/16th diamature pins on 1 1/2 centers and are 1000 watts and higher. The madium bipost have 1/4 inch post on 7/8th inch centers and run from 500 to 750 watts. These no longer have the large glass bulbs but use the smaller quartz halogin bulbs on these bases.These bases are listed in the catalogs this way.

Hi! Here's another 10,000w bulb listed at the moment on eBay:

Hi, guys! I bought the 10,000 watt Mazda most ecently listed on the bay for a BUY IT NOW of 250 bux! My username is louionthepickleboat--it's my sisters' ebay account I simply share with her! I'm Rick "C-6" Delair, and some of you may already know me. I have a yehoo group, oldelectriclightbulbs@yahoogroups.com and another one, rixsilverlinersnsuch@yahoogroups.com for streetlight talk. This stunning MAZDA is another addition to my very large and growing collection, and I'm working on an actual light bulb museum as I write this! It
ll be housed in a surplus 45'x8.5' house type trailer--actually fitted out originally for concession use. It'll be a stunning display, and will do away with the term "trailer trash"----nothing in THIS trailer is trash! I've been collecting bulbs for many years! And if you see louieonthepickleboat bidding, stay away (just kidding!)! I bought a wonderful NOS Mather-Perkins socket for my NOS Sawyer-Man 1884 bulb from the Mount Vernon Museum, (bulbmogul) and it's also stunning! I always wanted a 10,000 watt bulb, but never dreamed I'd own an early version! WOWEEEE!!!!! Anyway, later! Rick C-6!

Anyone have a picture of this one? It's been pulled on the listing....
Welcome to the bulb forums Rick!

Well, I had the chance to buy the 10,000 watt bulb too. I even had the chance to bid exactly $50 (the minimum bid) so that the Buy-It-Now would disappear, but I decided not to do so... I don't buy bulbs for that much anyway. I rarely pay more than $35 for a single bulb. I have paid $35 or more for like, 2-3 bulbs from my collection (out of hundreds). I don't have enough money to spend that much on bulbs either.
I have all 5 pics of the 10,000w bulb, here's one:

Fascinating pictures of these monster 50,000 and 75,000 Watt bulbs. Just out of interest, what voltage were they designed to run on ? Did they have any real application, other than commemorative "specials" - were they ever illuminated ?
-
An excerpt from "The Tungsten Filament Lamp" by W.E. Forsythe and E.Q. Adams, 1937 (before the 75-kw lamp existed)
"A few years ago a 2000- or a 2500-watt incandescent lamp seemed large; but now, as the result of developmental work, 10,000-watt lamps are manufactured and are regularly used in the motion-picture industry, airport lighting, and in some other places where high intensity illumination is desired. To date, the largest incandescent unit that has been attempted is the 120-volt 50,000-watt lamp, which only a few have been made, for special illumination and display. These have operated successfully and the strength of the various parts has allowed the lamps to be shipped from coast to coast without any breakage; thus, it has been demonstrated that a successful 50-kw lamp can be made if necessary."
Other stated facts of interest:
10-kw lamp when operated at 120 volts produced 280,000 lumens with a max. candlepower of 33,000, 29 lumens per watt.
50-kw lamp when operated at 120 volts produced 1,400,000 lumens with a max. candlepower of 166,000, 29 lumens per watt
The 50-kw lamp weighed over 35 pounds and was made of Pyrex and had a life span of only 100 hours.
