“With over 20 facilities throughout Cork & Kerry, sending electricians to different sites to fix lights that had failed was costing us thousands every year. Since PereGreen retrofitted all locations with their energy-efficient LED lighting system, not only have we reduced energy consumption by almost 70%, we’ve also completely eliminated maintenance costs. PereGreen were great to deal with and I highly recommend them.’

Primary Healthcare Service Provider South West Region.

“Business continuity is critical in the medical device sector. We operate 24 hours a day, 7 days a week and cannot risk unscheduled downtime for maintenance. The intelligent lighting system recommended and installed by PereGreen ticked all the boxes – high-quality components, a 10-year warranty and extremely efficient to run across the facility. PereGreen worked efficiently throughout and results have exceeded expectations.”

Fergal Moloney Facilities Manager Beckman Coulter

“Given the detailed nature of our operations, excellent light quality is essential on our factory floor. PereGreen retrofitted our existing facility and designed a bespoke lighting system for our new factory extension. They also managed the installation and the results have been incredible. Light levels have increased by almost 45% and we’ve reduced lighting costs across the facility by over 80%.”
