1000 Watt Bulb

[Kathie]

I have a 1000 Watt GE bulb.  It is clear glass in the shape of a reular bulb.  The difference is that it is 12" tall and 6" at its widest part.  The base fits into the old style tri-light.  This bulb was found in an old warehouse.  Also, it works.  I would welcome any information about this bulb.

Thanks, Kathie

Is this your bulb?

Hi Kathie,

I recently found exactly the same lamp as shown in Yoshi's picture. The brand of my lamp is Ekco ensign electric Ltd (made in Britain TJH 1000W) and is still in its original box. Unfortunately I do not know what the lamp is for, but the place I found it may indicate something, as it was in the old photographic room of a university in London. However, I am still not sure what it was used for and would like to know. So if anyone out there can tell me, please let us know. I am particularly interested around which year the lamp was made. (Also I found a lot of old but clearly never used projector lamps in their original boxes, are they interesting?) Thanks a lot,

Marcus

Hi Marcus,

I worked at a High School in Michigan and we used this type of bulb to light are football field. They were on a very tall wooden pole with about 20 lamps. I think they may have been 750 watts. We had to call a man out that could climb to the top. I'm glad the boss did not make me change the lights.

Hi everybody!
As have been appointed, these gasfilled lamps were used some years ago as high output photographic lighting sources, before the continuous light halogen bulbs and electronic flash units where marketed.
You can see a sample of these huge bulbs at my website's page:

I get this 750w Nitra from an old photo studio in my town among another two 500w made by Philips, all of three are 130V and E4O based.
Best regards,

M. Gonz?lez.

Hi,

I work at a local city owned auditorium and they still use 26 fixtures on the ceiling which is 50-60 feet high! The bulbs are 750w PS-52, clear and 120v. Recently I changed out 5 of the bulbs which had burned out. Relamping them was easy because the fixtures are easily accessed from the attic above. Let me tell you, those lamps really go when they burn out! One of the bulbs arced pretty nastily as I started to unscrew it and it almost blinded me and I could see the images in my eyes for 30 minutes! BTW the bulbs are all Sylvanias.

I have about 20 of these bulbs.  1000 watt, 1500 watt, and 2000 watt. They were originally used for lighting the sets at night of movies in the 30's and 40's.
I use them for 'painting' the inside of a building when I want extreme sharpness and no movement of people.  I set my f-stop to f128, open the shutter, pull the slide and paint with light.  An exposure can take as long as 30 minutes, but the people dont get in the picture and the resolution is fantastic.

If you go to http://www.mole.com/aboutus/history,  you will find a whole history of yoiur bulb.

Love and God Bless
