Fitting electric lighting is a job that requires awareness and knowledge of the systems involved. A qualified electrician is required to install the lighting and to confirm the lighting arrangements are safe, and completed to a high standard.
There are many services available from electricians. These can range from energy efficient LED and OLED lighting to planned lighting maintenance programmes.
It is also worth while to note that installing an effective lighting control system alongside the main system can save energy and money. A quality electrician will recommend a control system suited to the type of lights he or she is installing. For example lighting for a large office complex would be suited to a completely different set of controls, compared to a single room light.
Always check with the electrician what services he or she recommends in regards to the type of lighting you are interested in. They may have an alternative which could be more energy efficient and save you money.
