Anyone seen a lamp like this before?

I have seen them in the USSR. They used to use these in construction sites for some purposes, I forgot which. Like marking cranes etc.

Hi David,

Thanks for the suggestions. I'm in Shropshire, England. I had a look at the Source Antiques site but can't see any lights of this design on there at the moment, but there is some pretty nice other stuff. Maybe I should e-mail him a picture of the lamp and see if he can get the glass? I'm not bothered about the glass being red as I want to use the lamp for ordinary lighting.

The globe is essentially a cylinder with a hemisphere on the end and about 1/4" thick. I think it probably has a lip on the upper end but I can't tell for sure as I haven't been able to disassemble the lamp yet. Do you think it would be straightforward enough to blow?

Best wishes,

Chris

"cold war era"? Huh! It's an old lamp from the former DDR. That's it. Nothing military-related.

Not too uncommon. The only difference is the cast housing. But ...

It means "Explosion" = explosion and "Schutz" = protection. "Ex"-stuff is used mostly in mines and means that it won't spark when switched on/off. I guess that the "Sch" means here, that it is water tight (spray water). I would say that they used it because of it's rudgedized design.

HTH, Nick

Do you mean beyond the fact that you see lamps with that general design anwhere that a heavy-duty, rugged lamp is needed? Caged lamps light that are everywhere; we have at least four of them lighting up our barn

-- the cage keeps the glass from shattering all over the horses if they start to act up.

I thought you were UK based. Might be best to email a photo to Rod Donaldson at Source with some dimensions, he's on broadband. He may have something stashed away. Not everything is on the site.

Blowing it should not be difficult, if it requires a flange at the top then it will most likely have to have a punty mark at the bottom but this can be ground out and polished. If no flange, just straight sided, then the piece could be cut from the blown item leaving what you want without requiring a punty.

The punty is the small piece of glass used to hold the glass to another ir> David Bill>

When I said "Cold War era" I just meant something that was made in Eastern Europe sometime between 1960 and 1980. I didn't mean anything military-related. Maybe I'm using the phrase incorrectly, but I'm not a military historian.

That's interesting to know the meaning of the "Ex" and "Sch" marks. I read online that those triangular-headed bolts are often used on equipment designed for explosive environments, but so far I can't find anywhere that sells the right spanner (M6 I think it is). Might see if I can get one of those electricity meter box keys. Looking closely it also says "geprueft" between the "Ex" and "Sch" marks. Does that roughly mean "proven" or "tested" in translation?

Thanks for the information,

Chris

No, I meant this exact lamp. I've seen a fair number of similar ones too, but never one as heavy and solid as this. This is probably the weight of a brick!

Chris

Thanks for the information. I need to get a triangular spanner before I can disassemble the lamp, then I'll take some photos and e-mail the dimensions to Rod. If he hasn't got anything I might get back to you about the glass blowing.

Best wishes,

Chris

We use lamps of almost exactly that construction in the pyro trade for lighting work areas where explosive powders are present.

According to NFPA, there's nothing that actually qualifies as "explosion proof", but there are dustproof lamp enclosures that qualify for use in explosive dust environments. A different type is required for explosive gasses.

That's OK. "cold war" for me means something different. YMMV.

It's often used for "restricted" access. For example the FD uses some triangular locks on doors, cabinets, poles etc.

it means tested in the sense of approved.

I have seen lamps that looked like that on Navy ships. They were used as "night lights" and the red color was so as to not destroy your night vision. You could take a break from watch duty and return and still have the night vision.

Of course anything for the Navy was sturdy. Try marine suppliers for replacements.

Naval lamps are like that. Right and left - :-) Christmas colors.

I have a Japanese lamp that is very close in design.

It looks like the glass has been sprayed red on the

The Ex means that it is approved for use in an explosive atmosphere. I don't recognise the other letters Tom

Is the base size a standard medium thread base or is it larger, as in a mogul base?

Ut is NOT a running light as they have light baffle's so that they can be seen at specified angles.

Bill k7NOM

Do you mean the base of the bulb? I can't be certain yet, because I haven't been able to extract the remains of the bulb, but from below it looks like a standard Edison screw fitting.

Chris

More than like it is just a standard incandescent lamp. Very doubtful that it was any type of HID lighting. The portion of the filament assembly that is left looks like a common incandescent. Earlier post regarding xp for explosion proof could very likely be correct, possibly class 2 device. This is a typical design today for such fixtures from Crouse Hinds, Appleton, OZ Gedney and others.
