This logistics provider with multiple warehouses across the UK recognised an opportunity to radically reduce its energy consumption by replacing the current lighting at this facility with a more energy efficient technology. In selecting LED lighting as the solution, the business was able to cut its energy needs and achieve additional savings on maintenance as well as vastly improving the quality of light for its workers.

The lighting challenge

The facility consists of two linked warehouses jointly covering 20,000 sqms. The older of the two was fitted with 136 x 250W high pressure sodium lamps (HPS), the newer facility with 100 x 400W HPS and a few metal halides.

The Engineering Manager explains the lighting challenge: “Overall we wanted to save energy, but we also wanted to improve light quality. We found that the 250W HPS did not provide sufficient light quality in the older warehouse, which is why we moved to 400W HPS in the newer warehouse. However, they were actually averaging about 280W and 430W of power respectively. Also, sodium lights are not very effective at night and make it hard for the workers to read labels.”

Why Dialight

He adds: “The reason we chose Dialight is the length of time that the company has been in the market, whereas many of their competitors are relatively new. With the LED High Bay we have a very robust unit containing no hazardous materials that offers a 60,000 hour lifespan and is warranted by a well established UK company. Not only does it remove the maintenance and the disposal problem, it’s also a very workable light, perfect for reading labels.”

He points out additional benefits: “Although we installed light-saving devices with the sodiums, there was a 5-10 minute lag-time between switching them on and off, so we weren’t realising any particular benefit. The switching off also shortens the life of the lamps, but LEDs come on instantly and have no issues at all with switching.”

Energy savings

The business estimates that with LED lighting, this facility will be able to reduce its carbon emissions by 271 tonnes and save energy equating to 555,735kWh annually. Without taking the reduced maintenance needs or removal of disposal costs into account, it calculates a payback period of just over one year.
