About Eagle Air
Eagle Air is a wholly owned subsidiary of Air New Zealand with its Head Office and main Engineering Service based in Hamilton. Eagle Air operates 18 Beech 1900D aircraft servicing over 21 destinations on Air New Zealand's domestic regional routes and carries approximately 730,000 passengers per year. It employs over 200 staff including 33 engineers located in both Hamilton and Blenheim.
The Brief
Early in 2013 the management of Eagle Air Ltd approached J A Russell Ltd seeking a lighting upgrade for their Hamilton engineering maintenance hangar. The brief was to deliver better light quality, reduce maintenance costs and explore potential energy savings through utilisation of excellent daylight penetration when the hangar doors were open.
The Solution
The provision of a lighting subsidy from EECA Business Partnership meant that J A Russell Ltd was able to offer its client the best option of a one for one retrofit by replacing the old 400W metal halide fluorescent lights with a more efficient LED lighting system. 58 x 150W HiPak Pro LED luminaires suspended to 12m were installed in the 40m x 30m hangar. Each HiPak Pro LED has its own integral daylight and presence detecting sensor. The LED lights have a 50,000 hour lifetime and are expected to drastically reduce maintenance costs. To the delight of the customer, required lighting levels were achieved with an energy saving of 66%. Overall, the system will pay for itself in just 2.90 years.
