General Electric Pocket
This relatively uncommon bulkhead appears to be intended for the domestic market; owing to its simple and straightforward construction, and extremely basic lamp circuit.
Although boxed, the bulkhead had seen a small amount of use when it entered the Collection. Small 'windows' are cut in the cardboard, in order for the fitting to be seen inside. A great deal of space on the box is spent highlighting this bulkhead's advantages (energy saving and fewer lamp changes) over conventional filament bulkheads.
The bulkhead is made entirely out of self-extinguishing, impact resistant polycarbonate; making it suitable in areas where vandalism is a concern.
A raised section on the rear of the bulkhead contains various fixing holes for surface-mounting the unit. The ballast is also housed on the inside of this raised section, so as to reduce the depth at the front of the bulkhead. The five vertical slats that are located roughly in the centre provide some ventilation to the ballast during operation.
Unusually, the two pieces of polycarbonate that make up the front cover are not joined together and must be removed separately from the fitting. The panels are removed by inserting a small screwdriver into one of the edges, and then gently levering them out.
Removing the lamp reveals a small identification label attached to the reflector.
Two screws hold the reflector in place; with these undone, the reflector lifts out, revealing the aforementioned ballast and main terminal block. There is no capacitor fitted, and the starter would be fitted within the lamp itself. Owing to the bulkhead being constructed entirely in a non-conducting material, there is no requirement for an earth to be connected.
