This is an excellent example of an original high bay ships lamp which was salvaged from an old Japanese ship dating around 1975.
Its dome like shape is very unique and we have only seen a few like this, a great design feature is found where the steel meets the glass frame creating seamless transition between the two materials.
Original electrics have been replaced with the usual Loomlight wiring system and the bulb holder is now an E27 ceramic fitting.
To change the lamp simply unscrew the wing nuts to open the hinged lid / glass face.
The condition is great with some nice patina of age and no corrosion.
