Lit up: an LED lighting field trial
The Energy Saving Trust recognised the potential of LED lighting several years ago. In 2008, we successfully bid for funding from the UK government’s Environmental Transformation Fund to conduct a field trial into the feasibility of installing LED lighting into communal areas of social housing. Communal areas included stairwells, corridors and common rooms. Cost-effective, functional lighting is especially important in social housing, where communal areas are illuminated up to 24 hours a day.The trial measured the performance, energy-saving potential and maintenance of light levels of over 4,250 LED light fittings across 35 different sites. We found that LED lighting can:
• Significantly improve the lighting in social housing
• Reduce energy consumption
• Lower the cost of maintenance
The field trial categorically proved the effectiveness of modern LEDs as an energy-efficient source of light. The quality of lighting showed marked improvement at almost every site in the trial. This is true in terms of brightness, colour and distribution of light. The improved performance of LED lighting when compared with previously existing lighting in the test sites is clearly demonstrated in the “before and after” photographs in the appendix.
