OT: anyone know what these are?

Featured Posts

They’re lights of some kind.

 

At a guess I’d say they’re about 500mm diameter at the bottom. I can’t get at them at present to measure more accurately.

Anyone recognise them?

They look like brooders heat lamps for chickens/ ducks etc, but they would normally have an IR heat bulb in them.

 

Size overall and enormous heatsink vanes is what makes me think this.

Yep, I was also just about to say that they reminded me of those lamps to keep chicks warm but with the heat aspect missing.

We have a number of 'heat lamps' that we use on chicks and lambs etc, but I have never seen one with glass in it.

They are simply a reflective shade with an infra red bulb.

I have never used/seen a brooder lamp with glass apart from the bulb.

Yeah, that’s why I used the word ‘reminded’ as I am no expert on chick raising but have seen lamps similar to that shape used in that sort of application.

Rather than a 'heat sink' I think the ball on the top looks like one of those air freshener things that you put a smelly disc in, It may be a standard '70's light fitting but the heat from the light may be used to disperse the smell ?

Yeah, I'd say it dates from the 50s or 60s.

 

There used to be a reason for not letting poultry peck at the bulb, maybe the bulbs were fragile.

 

Most of the new ones are a cone of galvanised steel with a tough bulb in them, but the ones pictured look like some my Uncle had on the farm when I was a kid.

Possibly, but the lights should be suspended high enough that they couldn't peck it - normally about 2 feet high is the 'right height' and the bulb produces a cone of warmth / light.

 

Too low and the heat burns them and you cannot get many chicks into the cone of warmth, too high and there is insufficient warmth. As the chicks get 'stronger' you raise the height to start to wean them off the heater.

 

You must have had very 'posh' lights (or used standard light shades with IR bulbs) - in the 60's (and still today) our lights didn't have any glass.

Pinched from the church hall would be more likely than posh lights!  Farmers eh ... :D

 

It's possible they were repurposed from something else, I just remember them being like that.  The back of the lamp is huge though, so it must serve some other purpose than just a bulb holder.

 

I'm not sure your air freshener theory is quite right though.

I thought the same but they’re much too high - about 20ft in the air.

They’re disconnected but located in what used to be a cow shed. I asked the farmer if they were ‘cow warmers’ which got a laugh. He replied “No, they’re skip fillers unless they have value”

Drew will pay about £100 each - they are his speciality,

I’ll let the farmer know... or I’ll remove them and sell them myself ;)

That thing on the top almost looks like a later addition and looks a bit like an insect killer thing, I think you used to get them with replaceable insecticide impregnated pads

I think there are 4 in total. You can see 2 of them in this piccy...

The thing about lights suspended from chains is you can trivially adjust the height if there is enough cable. :)

 

I'm glad they are in a cowshed though, it proves I'm not totally insane with the agricultural link!

I think the holophane glass in the front probably acts as a fresnel lens.


I’ve just been given the authority to sell them so if Drew PMs me (what’s his username here?) we can sort summat out. 


Thanks all :)

That ball on the top is around a foot or more in diameter. I suspect it’s ballast for the lamp or something similar.

Yes I think it is, I was only joking about the air-freshener.

 

I believe they are part of the 'gallery' that attaches the light to the chain.

Yeah, I was wondering if they were designed for mercury vapour lamps originally.

 

They are probably worth more cleaned up and rewired, probably with one of those fancy LED filament bulbs of an appropriate size.  Do you know anyone who likes faffing about with wires? ;)

Funny you should mention that...

 

Sadly we’re shifting premises within the farm where we’re located so I’m somewhat busy at present. If Drew (or anyone else) wants them then all I need is an offer :)

We used to have that style of lamp in a factory I worked at.  In their day they were considered very efficient with a reasonable colour output, from memory they were a mercury discharge lamp with a big ballast above.  All gone now and replaced.

Cheers, I suspected that the top bit was a ballast for a discharge lamp. :)
