At the 35 sites in the field trial, the report calculated that the LED fittings saved more than three million kilowatt hours each year when compared with the previous lighting. The technology is also much more energy efficient, using up to 90% less energy than incandescent bulbs. “We like to test things in-situ in order to understand their real performance rather than rely on manufacturer...
