Peter Longworth, Energy Initiatives Officer with the Isle of Man Government Department of Environment, Food & Agriculture explained: ‘This project has provided a very impressive 67% electricity saving, with a payback of under 4 years as we have been able to better light the car park levels with less than 300 fittings, compared to nearly 600 required before. These modern light fittings last three times longer than the old ones, so further savings come from reduced maintenance needs.’
