Household Lighting is generally broken down into three categories; Specific Lighting, Task lighting and General lighting. General lighting provides all round illumination to an entire area or even room. Task lighting, is used for reading, sewing etc as well as the general lighting to help visualize certain objects. Specific Lighting, as the name suggests, is Lighting for a specific purpose such as picking out a painting or focal point in a room without flooding the surrounding area. When creating your lighting atmosphere think of the area and what activities you may do in the rooms or areas of the room. All rooms require a level of general lighting, you can add dimmer switches to change the atmosphere to suit your mood or time of the day.


When choosing Low Voltage Downlights for a complete room you may wonder how many to install. Each room is going to need a different light output. SELDirect's suggested guide - 1 x 20 Watt Halogen Downlight per square meter or 1 x 50 Watt light per 1.5 square meters. Allowing half a meter in from the walls of the room. All transformers sold by SELDirect are dimmable and can be controlled with a dimmer switch.


12V Lighting transformers are normally hidden in the ceiling void and it is crucial to make sure they are in a well-ventilated area. Never cover them with insulation or put them near heating pipes, as Halogen Lamps drive the heat backwards. All transformers have a safety thermal cut out that will work when the transformer temperature becomes too high. The transformers also have an automatic reset device that will instantly reset when the temperature cools. We also sell a fire hood for non-fire rated downlights so you can keep up with safety regulations and prevent a fire.


Bathrooms have different regulations and need certain IP ratings in each zone of the room. The current regulations state a bathroom is divided into four separate zones. For more information on bathroom zones and regulations click here
