Sweet savings for Silver Spoon

Energy-efficient lighting systems, designed by Chalmor and featuring Resilience and Brilliance light fittings and Autolux controllers, are helping The Silver Spoon Company, part of British Sugar, to reduce the carbon footprint of its production and distribution facility in Newark. Savings on lighting in the loading bay area are projected to give a return on investment of just eight months, while upgraded lighting in a mezzanine production area has a predicted payback of 18 months.

The loading bay was originally lit by a mixture of T8 and T12 fluorescent lighting, with 80 fittings in all. These have been replaced by 42 IP65-rated Resilience fittings, each with a single 54W T5 fluorescent tube, reducing the installed electrical load from 12.4 to 2.27kW.

Arranged in six rows of seven fittings, the first three rows of Resilience fittings are linked to an Autolux controller to provide daylight control. As the outer perimeter of the loading bay experiences high levels of natural daylight, it is anticipated this will reduce the electricity consumption of those 21 fittings by around 40%.

On the mezzanine production area 11 400W high pressure sodium fittings have been replaced with 10 4 x 54W Brilliance T5 fittings, reducing the installed load from 5.28 to 2.16kW (including ballast losses) and greatly improving lighting levels.
