The client had a mixture of fluorescent tubes, GU10 halogen lamps, metal halide bay lights and sodium floodlights and were looking to reduce their energy consumption throughout the site to reduce their carbon footprint.
They also had on-going issues with the current light levels within their despatch and production areas which was causing picking and packing errors.
In addition to the lighting circuit’s high energy consumption within the temperature controlled areas, there is also more power consumed by the cooling system to maintain the desired temperature.
This is due to the inefficiency of the metal halide lights producing more waste heat that had to be removed by the refrigeration system.
This is often referred to as the coefficient of performance or COP, please see attached datasheet for full explanation.
Maintenance on the current lighting system was a very expensive task as accessibility to the bay lights was some what reduced by production machinery on site. A product with a lifetime increase was required to reduce this as much as possible.
