Lighting the Future: Energy Saving Trust’s LED Lighting Field Trial


The Light Emitting Diode (LED) technology has been gaining global recognition and popularity recently for its unique and eco-friendly features. Aside from giving off a brighter light, LED lighting fixtures also last far longer than their fluorescent counterparts. This results in financial savings for your business or home in the long run. LED products also consume less electricity. This energy-saving capability is reflected in the monthly electric bill of companies, establishments as well as public and private offices that have made the switch.

Energy Saving Trust (EST) is championing this cause for over sixteen years now. One of the recent studies conducted by this UK-based organization is a field trial of LED lighting fixtures in social housing facilities. The organization believes that they are playing a vital role in helping shape the LED lighting market in the UK.

After observing and measuring the performance of 4,250 LED light fixtures in 35 sites, here are some of the significant findings of EST, as published in their report.

  1. Lighting levels increased in both phases of the field trial. In phase 1, the increase was 100 percent. In phase 2, it was 57 percent.
  2. Installed LED lighting fixtures in the sites can generate ongoing savings of more than 3,372,058 kWh per year in both project phases once LED performance is normalized. This energy-savings can light 5,788 typical UK homes for a year.
  3. The LED installations increased the “colour temperature” in buildings which gives a brighter, whiter light that is much closer to that of daylight. Colour temperature is the measurement of how “warm” or “cold” a light is.
  4. The brighter, whiter light enhanced the ambience in most of the sites as illustrated in the photographs in the report’s appendix.
  5. LEDs in the trial demonstrated an excellent sustained performance. After about six months of use, lighting levels were at 93.6 per cent on the average.
  6. Using normalized figures, both phases of the trial suggested that return on investment could be around 2 years.
  7. Colour rendering improved across most of the sites. This means that colours appear as they would under normal lighting conditions

This study proves that the LED lighting technology is really for the next wave of lighting fixtures. Thinking of how to save while keeping your store hip and attractive to customers? AffordableLED offers a variety of scrolling LED sign that would surely grab attention for your store.
