13,000 sensors cut lighting energy at warehouse

Some 3,600 programmable dimmable sensors control the background lighting after non-occupancy while a further 10,000 switching sensors turn the luminaires on for the distribution staff at the 46,000 square metre facility in Hatfield, which stores garments a for a fashion brand.

OVER 13,000 sensors are keeping energy costs down at a retailer’s warehouse in Hertfordshire.

The distribution centre, which is divided into two areas, one for boxed items and one for hanging garments, have been fitted with more than 13,600 of Ecolighting Sapphire luminaires.

Some 3,600 programmable dimmable sensors control the background lighting after non-occupancy while a further 10,000 switching sensors turn the luminaires on for the distribution staff at the 46,000 square metre facility in Hatfield, which stores garments a for a fashion brand.

The distribution centre, which is divided into two areas, one for boxed items and one for hanging garments, have been fitted with more than 13,600 of Ecolighting Sapphire luminaires.

They feature high output chip-on-board LEDs and Osram drivers in a linear body with a polycarbonate diffuser, all rated IP54.

The 1500mm length luminaire comes in four power ratings of 40W, 50W, 60W and 80W, with up to 9600 lumens, a colour temperature of 4000K and colour rendering of RA80.

Both warehouses also benefit from over 2,600 Altos emergency lighting LED luminaires and each have the Rapid emergency system installed.

The existing site, which opened recently, was formerly used by another retailer and has been converted into a mechanised clothing distribution centre and serves 150 stores in the South East and employs more than 500 people.

Apart from the lighting, the electrical tender also included ancillary electrical works including PA systems and fire and smoke detection.

Following a competitive tender process, the main contract of more than £16m was awarded for the works.

The site was also fitted with external lighting. 100W and 200W Atlantis LED floodlights and 35W, 60W and 200W Medusa amenity lights were selected. They have frosted tempered glass cover for uniform illumination and offer IP65 protection and a luminaire efficacy of up to 115 lumens per watt.
