This is a refurbished Patt 123, which is one of the most sought after of the vintage theatre lamps. It’s egg shape being one of the easiest to recognised. Its has been stripped down and black powder coated with polished accents. Fitted with a ceramic ES/E27 lamp holder, so it can be used with a wide variety of domestic light bulbs. From a 25watt (or LED equivalent) giving a nice warm glow to a suggested max of 100watt giving some area illumination. There is also a focus knob on the bottom so the spread of light from the lens can be adjusted from wide to narrow. Please note that the lens does have a couple of small chips to the outside edge but this in no way affects the lights function, its just showing a bit of it’s age,
