400W metal halide lamps were replaced with 99 LEDs to reduce wattage, reducing the environmental impact and cutting energy costs by almost 80%.
The new LEDs are rated at 175W and in the company’s warehouse, the new lamps are 86W.
Both are set at only 50% usage with daylight-harvesting being used.
This automatically reduces the power to the lights if the sunlight is bright.
During February the company will start the second phase of replacement lighting in the proofing zone, office suites and exterior lights where all bulbs will be exchanged for LED’s.
The 80% reduction in energy costs so far means that £36,000 invested for the first phase of the company’s light-replacement project has a pay-back of 18 months.
