We as electricians have recently started to see a rise in the number of installations using LED lighting, this type of lighting can offer up to 85% cost savings over traditional forms of lighting and is considerably ‘greener’ than traditional lighting methods.
The biggest area we have seen is in the GU10 type of fitting, many homes/businesses having down lights installed and this is an area where major savings can be found, we recently converted a major restaurant to LED, having over 80 fittings within the installations they can expect to make massive savings over the coming years, and the light emitted is much smoother using a mixture of warm white lamps for the seating areas and cool white for the bar/foyer areas.
The cost savings are the most obvious reason for installing this type of fitting in your home or business and I would almost certainly recommend anyone to install them for that reason alone.
Also the prices of the actual lamps/fittings are coming down as the technology and manufacturing costs improve.
