LED Lamps

External lighting can make or break a scheme. Done well, it can enhance both the landscaping and the architecture of a project

This year Marks & Spencer replaced the interior lighting in 170 of its stores with LEDs as part of a move to reduce the energy usage in its shops, offices and warehouses by 35 per cent per square foot by 2015. It is just one of many retailers that have acknowledged the benefits of using LED lighting systems to reduce energy use. Compared with compact fluorescent light fittings, LEDs offer significant energy and cost savings.

For most applications, cost has previously been an obstacle for using LEDs, but as these are beginning to drop and the subsequent benefits are becoming more widely acknowledged, the use of LED lamps is gradually increasing.

There are three different types of LED light fittings: those in which the LED is permanently embedded into the housing, those in which the LED is a cassette, and those in which the LED is a lamp or bulb that is intended to be retrofitted into existing light fittings. It is this last group of lamps or bulbs upon which this product matrix focuses.

One of the most significant benefits of LED lamps is their long lifetimes - typically, they last up to 15 times longer than conventional light sources. These longer lifespans reduce the need for re-lamping, which not only saves costs on maintenance, but also reduces the amount of disruption that is caused when this needs to be done.

LEDs are often criticised for the quality of white light they produce. There is currently no industry standard for the production of white LEDs and it is not really possible to guarantee a uniformity in the whiteness of light output produced by different manufacturers. However, that said, the quality and variety of LED light fittings has increased significantly in recent years and, as demand for low energy lighting increases, so will the developments in LED technology.
