The new lights installed by Southport based firm Morgan Hope, work by motion detection and switch lights off when no one is there. The lights will be fully on when an area is occupied but will dim to 50% after five minutes if the area empties and to just 10% after another 2.5 minutes. This hibernation system is estimated to reduce the hospital’s energy cost by 90%.
The hospital already uses a green energy system with turbines generating power. The hospital also estimates the lights will reduce it’s carbon footprint and save more than 190 tons of carbon per year.
Sustainability and energy manager at Liverpool Royal Hospital, Andy Johnson been delighted about the results. It been fitted with minimum disruption, also helped to improve the patient environment and brought positive feedback from staff. He added: “The ward lighting project reflects the Trust’s continuing commitment to reducing its energy consumption and carbon footprint”.
Morgan Hope sales director, John Murray said, that “traditional switch start fluorescent lighting is very wasteful in terms of energy. The existing lights in the hospital use more than 100W of power per light fitting while new high frequency T5 lamps only needing 56W”.
