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 These have been replaced by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.
