Hunts Case Study

Hunt’s Foodservice is a leading supplier of frozen, chilled and ambient foods. After completing a successful ambient project using the Verteco luminaire, Dexeco were approached to offer an energy efficient solution for their large freezer warehouses.

These areas were previously lit using 250W sodium lowbays, which operate continuously throughout the 12 hour working day. With low occupancy levels it was clear that a sensor controlled luminaire would return instant savings. The Coldbay LED with integral R11 sensor offers low temperature presence detection and dimming along with benefits such as a higher colour rendering with whiter light and better light distribution.

“Following a 15 day onsite trial the Coldbay LED returned an 88.1% energy saving.”

Following a 15 day on-site trial an 88.1% energy reduction was achieved. This trial also demonstrated significant refrigeration and maintenance savings, equating to a total combined saving of approximately £3813.97 per annum.

When combining these savings with the other benefits of the Coldbay LED (see page 48) such as glass and mercury free operation and constant light output (with zero lumen depreciation after 50,000 hours of operation), Hunt’s Foodservice decided to install Coldbay LED throughout the entire freezer unit.

“The Coldbay LEDs in this case study will be operating at just 10% output for the majority of their life. This could potentially allow the LED modules to operate far beyond their expected 50,000 hour life.”
