Plain and twisted candle lamps are made in 25 W, 40 W and 60 W sizes and in pearl, plain, amber and silvered colours. They are made in be (bayonet cap) and sbc (small bayonet cap) versions.
These are used for wall lights and for period pendant fittings.
These are sometimes called ’strip lights‘ and are non-fluorescent, being tungsten filament lamps. There are two versions, one type is commonly used for applications in the home, and the second type is known as architectural lamps‘. Read the rest of this entry »
The amount of light given out or produced by an electric lamp — bulb, striplight or fluorescent tube — depends on the type of lamp and its wattage. The light produced is measured in lumens and a bulb or tube of a given wattage produces an average output of so many lumens. This will continue throughout most of its life.
Equally important is the number of lumens produced for each watt consumed, so it is usual to say, when comparing types, that a bulb or tube produces so many lumens per watt. The more the lumens per watt, the higher the efficiency of the lamp. Read the rest of this entry »
Table lamps, floor standards, bedside lights and other portable lights can have dimmer control using any one of three methods. One method is a dimmer socket adaptor which plugs into the standard 13 A socket-outlet. This unit has two 2-pin sockets and is especially suitable for controlling two bedside lamps in a twin-bedded or a double-bedded room. The control knob on the adaptor dims both lamps at the same light intensity; they cannot be controlled independently.
Another method uses a line-cord dimmer which is wired into the flex of the lamp. The dimmer can be a standard wall type mounted on a plastic box and placed on the arm of the chair, table, desk, or any other chosen position. Alternatively, it can be a mini-dimmer switch resembling a torpedo table lamp switch. This type is especially suitable for the individual control of bedside lamps. Read the rest of this entry »
Of more unusual interest is a rise and fall pendant enabling the height of the light, suspended by the -sheathed flex, to be adjusted as required. One application is in the dining room over the dining table. As the light unit is raised the flex winds into the rise and fall unit in the ceiling plate. Matching fixed-height pendants are also available. The rise and fall principle is a development of the old rise and fall pendant operated with a system of pulleys and ballast weights.

Take particular care in the bathroom where special regulations apply.
Do not install a socket-outlet in the bathroom other than an approved shaver supply unit for a mains voltage shaver.
Do not make provision for using a mains voltage portable appliance. For example do not run a portable electric heater from a socket-outlet situated outside the bathroom i.e. on the landing or in an adjacent bedroom. If the tank cupboard opens into the bathroom and the tank has an immersion heater do not supply it from a socket-outlet (not a good method in any case) which could be used for plugging in a portable appliance.
