Lighting the way for a quick pay-back
June 1st 2008 Several months after
lighting and controls at
Wincanton's automated
distribution centre in Corby
were upgraded, energy
savings indicate that the
company is on target for
realising a projected
payback of just 1.6 years.
Existing 400W SON (high
pressure sodium) fittings
were replaced with
Chalmor's 4 x 54W and 2 x
28W Brilliance fittings on a
point for point basis to
provide higher lighting
levels and better colour
rendering for a reduced
installed electrical load.
They are combined with
Autolux controllers linked to
daylight sensors and
occupancy detectors.
Lighting can be dimmed
when daylight levels are
sufficient, and switched off
in unoccupied areas.
The Brilliance fittings
have enabled re-lamping
schedules to be extended to
three years or more, as they
offer a 30,000h life.
The Brilliance fittings can
be switched in a variety of
combinations to vary light
levels. For example, for low
background lighting just
the 2 x 28W lamps can be
switched on, and these can
be dimmed to compensate
for natural daylight. In
addition, the lamps are
addressable through the
Autolux controllers so that
'lead and lag' lamps can be
alternated to ensure even
burning hours for all lamps
in each fitting.
Better colour rendering
has generated positive
comments from warehouse
staff, especially on the
night shift, as it makes
picking much easier. More articles from Chalmor Limited: |
