Unusual bulkhead lamps
I bought these bulkhead lamps last weekend. I have scoured the web all week trying to find out about them but to no avail. The high impact plastic half globes are made by Arrow Plastics and are not sealed into the hinged housing. The rear "reflector" is of painted steel, the remainder of the housing is alloy again with no hermetic sealing. A standard bayonet cap type fitting is installed in each unit. There is a code number on the upper surface of each luminaire which is AP17171 and LM6M and there is a "B/L" logo in a circle at the top. The lamp housing fastens onto a base connector where single core cables feed in and connect to a terminal block, this mates with "bayonet cap" style pins on the main housing so that when the housing is attached to the base then connection is made. The base unit appears to have been made by GEC. I am suspecting that these lamps were made in the 60s or 70s maybe for a cargo ship or oil platform. Any suggestions would be welcome.
Neil

Re: Unusual bulkhead lamps
There are a couple of something like what you have got on a shed by an old gas holder visible through the safety barrier from street view.

Re: Unusual bulkhead lamps
Could the AP stand for 'Admiralty Pattern'?
I think there is a Aluminium alloy called LM6. |

Re: Unusual bulkhead lamps
Hi,
If they were for use on oil platforms, I'm sure they'd have an EX mark on them somewhere. But they certainly look designed for heavy duty. Cheers, Pete.

Re: Unusual bulkhead lamps
Thanks for your help everyone so far on identifying these, they do appear to be a bit of a mystery. It is surprising that they are not sealed, although they are otherwise very well built.

Re: Unusual bulkhead lamps
Hello. Sorry if I am late and this has been identified. I was wondering if you could post a close image of the "BL" you mentioned. Also, these lights do look quite nice.

Re: Unusual bulkhead lamps
Hello Otter, just seen your post. The B and L were separated by a vertical line, the whole encircled rather like the Belling Lee trade mark. You can just make it out towards the bottom of image 1 on top of the bolted flange on the left hand lamp. I have now swapped the lamps for a Dualit cooker - needs must .
