Riegens HB Saleni T5
fluorescent luminaires are
helping SIG achieve average
energy savings of 65 to 70%
on its UK warehouse lighting.

SIG worked with the
Carbon Trust to evaluate the
energy performance of its
320 UK sites. Warehouse
lighting was identified as an
area for improvement. The
company opted for Riegens 2
x 80W HB Saleni fittings
which offered improved
lighting levels and provided
control opportunities. The
whiter light of the T5
fluorescent lamps has also
improved lighting quality in
sites that have been upgraded.

The company set a
payback period of 5 years,
and expected to achieve 65 to
70% savings on lighting costs.
Some sites have performed
better. Plymouth, for example,
has achieved a 79% saving
with a 2-year payback.
