This is a bit of a rarity, turned up at my favorite boot sale for £1 or thereabouts, These require 2 power sources and this model uses a modified BC base 3 contacts and one of the pins of the base is thicker and would need a special holder.This would set up an arch....no not a mis spelling, originating from early arc lamps where the arc produced from horizontal carbons ( Davy ) was in the shape of an arch...later the h was dropped and the word arc was used ....sorry for the history

This looks like a DC model, as it have only one tungsten bead. [url=http://lamptech.co.uk/Spec%20Sheets/D%20IN%20Ediswan%20Pointolite%20150AC.htm] Here is the AC version [/url[ of this lamp.

I"m don't speak english well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I hope that LED won't replace all forms of other light

Unfortunately, due to not having a car, it's difficult to get to things like that around here

Sorry about that, but the bootsale I used was at Wimbledon but was really a collectors faire, most B/S you would not find such interesting items. The St Heleirs B/S at Sutton may turn up some nice things as I call it the new Wimbledon as many sellers from Wimbledon there....peter
