Low voltage lighting can be used in a variety of ways. It is used as a safe option in highly dangerous areas such as kitchens and bathrooms or simply to create an atmosphere in a dining room or lounge. Low 
voltage lighting is easily installed and in this project we have tried to look at the best ways to use Low Voltage Lighting.
The superb quality "specific" lighting you see in so many shops, art galleries, museums etc is called Extra Low Voltage Lighting (ELV) but is commonly (and mistakenly) referred to as just low voltage lighting. For the home owner this has opened up huge opportunities and existing lighting can be replaced, or just enhanced by the use of extra low voltage lighting.
Extra low voltage lighting consists of small tungsten halogen bulbs producing two or three times the light of conventional bulbs of equal wattage. They are powered by a 12 volt electrical supply rather than the 230 volts needed to power conventional lighting and are therefore fed through a (concealed) transformer. Through the use of this transformer, energy consumption may be reduced by up to 60% although this really only becomes apparent when several conventional lights are replaced. Additionally, bulb life is increased by about 3 times.
The halogen bulbs are fitted into special multi faceted mirrored reflectors with sealed fronts so they can be used safely in bathrooms and kitchens. They are described as dichroic reflectors which means that the majority of the heat generated by the bulb is reflected backwards and not into the room. The light, as a result, stays relatively cool.
Lighting in the home falls into three categories. General, Task and Specific. General lighting provides overall space brightness with no concentration on any part of a room. Task lighting, as you would imagine, provides light for tasks such as reading, sewing etc where general lighting may be inadequate. Specific lighting is intended to highlight specific features without giving out to much light elsewhere. When thinking about lighting for any particular room it makes sense to think about the function of that room and what will be done in there. Most rooms will require a level of general lighting which, by the use of dimmer switches, can be transformed into various moods. All the lighting products mentioned here, with many others, can be seen in our tool store by clicking on the tools below.
If you are using low voltage lighting for a complete room, the general rule of thumb is one 20W wide beam light per square metre or one 50W light per 1.5 square metres. This rule starts half a metre in from the edge of the room.
Generally Low Voltage Lighting transformers are placed in the floor or ceiling void and it is very important to ensure they are in a well ventilated space. Do not cover them with insulation, remember, the heat comes out backwards. Never position transformers near central heating pipes. All Newey Online transformers are fitted with a safety cut out which will operate if the transformer core temperature gets too high. The cut out will automatically reset when the temperature cools.
Bathrooms have strict regulations as to the type of light fitting that should be used, and where. Under the regulations, a bathroom is sectioned into four separate zones. Each zone of the bathroom is related to the position of the water source, ie bath, shower, basin etc. Bathroom lighting is given an IP rating. This IP rating is followed by a number and the higher both numbers are the better protection a light fitting has against the ingress of water. If you are unsure about the position of any light fitting you should consult a qualified electrician Please see our project on Part P of the building regulations.
Kitchens also are subject to special regulations and advice should be sought as to the placing of lights here.
