Welcome to the lighting collection at Aberystwyth University Physics Museum. This collection houses many pieces that have previously been used to light some of the Physics lecture rooms and workshops.
Arbitron Discharge Tube
By Armaments Research Dept. 1945
A tube filled with some noble gas that is ionised by an electric charge, causing the gas to give off a flash of light.
Metal Filament Gas Filled Lamp
By Osram G. E. C. 1940
A large 220 volt, 200 watt light bulb with Edison screw cap.
Cryselco Carbon Filament

A 220 volt, 32 C. P carbon filament bulb with R. A. F. pip seal.
Sunbeam Elongated Carbon Filament
By Sunbeam. 1895
An elongated bulb carbon filament lamp of unknown voltage.
Robertson Carbon Filament Orange
By Robertson. 1925
An 11 inch, orange 230-250 volt, 250 watt pip seal carbon filament lamp designed for use in a small heater with two other lamps. Also used as a resistance in charging wireless accumulators.
Philips ½ Watt
A metal filament 4 volt, 75 watt bayonet cap bulb. Named ½ watt because it gave 0.5 watts per candlepower.
A 12 volt, 24 watt metal filament gas-filled lamp possibly used as a car headlight.
C. A. V
By Royal Ediswan. 1925
Metal filament 6 volt, 15 watt car headlamp with bayonet cap and pip seal.
By BTH. 1925
An 8 volt, 6 watt metal filament car headlamp with bayonet cap.
Robertson Carbon Filament
By Robertson. 1930
A 220 volt, 32 C. P. carbon filament lamp with bayonet cap and sealed at base.
Tungsten Filament Vacuum
By Osram G. E. C. 1925
A 110 volt, 60 watt tungsten filament vacuum lamp with bayonet cap and sealed base.
Gas Bracket Lamp
A 6 volt carbon filament lamp designed to fit a gas bracket.
By Osglim G. E. C. 1930
A 230-240 volt, 5 watt neon lamp of the beehive type with bayonet cap and base seal.
By Osram G. E. C.
A large 230 volt, 1000 watt metal filament, gas-filled projection lamp with giant Edison screw cap.
By Siemens. 1940
A 240 volt, 500 watt metal filament gas-filled lamp that was used in the large Physics lecture room throughout the 1940’s.
Metal filament bulb with twin filaments, appears to be of an experimental nature. Possibly homemade.
By Osram G. E. C. 1935
A 135 volt, 18 and 24 watt twin metal filament bulb with bayonet cap. Used commercially.
By Oslim G. E. C. 1930
A 200-220 volt pilot type neon bulb with bayonet cap.
Mazda B. T. H Patent
By B. T. H. 1920
A 110 volt, 20 watt elongated metal filament vacuum bulb for use at a music desk. From an organ at Oldham Welsh C. M Church.
Broken Carbon Filament Bulb
This carbon filament has both its bulb and filament broken. Originally designed to fit a gas bracket.
Tungsten Filament Vacuum Lamp
By Osram G. E. C
A large 110 volt, 60 watt tungsten filament vacuum lamp with a sealed base and a bayonet cap.
Siemens Carbon Filament
By Siemens. 1895
A carbon filament lamp with unknown voltage. Possibly 100 volts and 5 C. P.
Osram Tungsten Filament
By Osram G. E. C. 1920
A 110 volt, 32 watt tungsten filament lamp with bayonet cap and pip seal.
By Osram G. E. C. 1958
A 240 volt, 500 watt projector lamp complete in box. The box is stamped “4 Nov 1958”.
By Sunbeam. 1895
Previously used to light either the original Physics Lab or Lecture Room. This bulb was originally 28 volt and 400 C. P, but was run off a 110 volt dynamo around 1900.
Nernst AEG Model B
By Nernst. 1905
A collection of these lamps were used to light the U. C. W. library until an unknown date.
