I'm not a linguist but is that German, making this the German variant of the US 60"? I have read just a little about some being made in Europe/Russia.

Ill bet it's even harder to get parts for this light than our US made version. Is it in working condition? Would love to see some of the other pics you took and one of it working if it does. I'll supply my email.

Yep, it´s a German version with a 60'' reflector.

It´s said to be working, but I don´t know for shure.


He did get 2 tons of rods with it....

WOW! that's a lot of rods! Can you find out the + and - rod diameter and if it looks like they are core filled with a different material? The US machine rods (the originals) are filled with Cerium to enhance brightness. + is 5/8" and - is 7/16"

My gosh, look at that thing! Typical German construction with everything over built to the hilt. Did you say "two tons of rods!?" haha...that's amazing.

The German ones are somewhat more powerful than ours (naturally, they had more to worry about), at 200 amps and about 100 volts at the arc. It used a 24 KW generator powered by an 8 cylinder engine.

They also had 200cm units, with 450 amp burners and were powered by 120 KW generators! No idea if any of those exist, much less operate. They also had seriously large carbons!

Our GE and Sperrys are pretty cool, and also well made, but they pale in comparison to the German machines.

Yes, 2 tons of rods :D

Info taken from my memory..

The average lifespan of a search light during WWII was 30 seconds in Germany. Then it was shot or bombed....:eek:oo:



This one has been standing outside since 1945 and still works...to do so it needs to be overbuilt.

I will put up some more pics later on. I took some from the inside showing the mechanism that feeds the rods.

So, got any pics of the generator? Inside the can? The rig as a whole? Where was this located? These and more questions, As The Searchlight Turns...

Just a little bit of information about carbon arc lamps that may be of interest-
The most efficient ones are around 36 lumens/Watt. They emit true Black body shaped spectrum at about 4000K, so I could suppose one could say they have near perfect CRI. I would not want to use one for lighting my bedroom though, they give off a tremendous amount of violet and UV light.

For comparison, the color temperature of the sun from space is about 5,900 K, before it passes through the atmosphere and gets attenuated down to a lower 4000-5400K correlated temperature. (btw, 4000K attenuated sunlight does not quite have the same spectral distribution as a true unfiltered 4000K black body, which would be more hazardous on the eyes)
