Explosion Proof Light?

[keithinuk]

Still about collecting junk & stuff I like, anyway I think these are probably ex-mod and even common, but I don't know what light they are from, I suspect explosion Proof type lights, but I don't know, as I can only ever seem to find the screw in type glass, anyone know?
Just under 8"x 4 1/4"

I don't think glass would be used for an explosion proof light though. Radio mast lights?

Turn them into giant "LED" lookalikes and use them for Christmas decorations / talking points.

Have you got an empty fireplace that needs cheering up?

Could be for emergency warning lights over doorways, keep out areas etc?

I understood that "explosion proof" as applied to electrical apparatus does not necessarily mean that it is capable of withstanding an explosion, but means that it can be used in an explosive atmosphere without the risk if initiating an explosion. They look like the glass cover to our outside light, which is clear, and has a flange and gasket for keeping it in place and keeping out the rain. It was already installed when we moved in more than 30 years ago.

They look a bit like the lenses used on rotating beacons fitted to emergency vehicles etc. but red rather than blue or orange. A bit taller though. What are they made of?

[McMurdo]

I think you're right, 'EX' rated beacons. I'm sure I've seen them surrounded by a protective cage. Somewhere like a refinery, airport, gasworks or coal mine. They would have been extortionately expensive...modern LED versions are around £800 a pop

I side with posting #2

There's a light with a red glass dome that looks very much like these on the end of Bournemouth pier, to warn shipping that there's a pier sticking out into the sea!. They look like a red version of the Coughtree dome.

If the glass is "ruby" glass, then they could be used as safelights for photograpic B/W processing, not that there's much call for this sort of thing these days.

I would say they're off old radio mast navigation lights, the ones that took an incandescent lamp beneath and have since been replaced by LED units. I have seen several of this size being chucked out from various places.

I guess that means they're not "Other Vintage Household Electrical or Electromechanical Items" then

Rather depends on where they are used, my darkroom (still used) is lit by LEDs now, I could use those though.

They are old Mast marker light lenses, ex RAF. Be interested to know where they came from, I know of only one source locally.

A shop in Hitchin, like all my other old MOD stuff.

The red one reminds me of the lamps that one saw on some electricity poles in parts of NZ back in the 1950s. They were fitted on those poles that also carried those red circular fire alarms (of the break-the-glass-and-press-the-button type), presumably to make them (the alarms) easier to find at night. The lamps were mounted below the electricity wires, and my recollection is that typically they were fitted at the end of a tube cantilevered horizontally out from the pole and bent downwards at around 30 degrees just before the lamp base. So the glasses also had the same slant.

Cheers,
