In January 2010 the ExCeL London
management team started looking at
how it could improve lighting to
achieve uniformity throughout the
central boulevard of the exhibition
centre which is almost half a mile
long. The solution chosen has
improved light quality,reduced
operating and maintenance costs and
improved energy efficiency.

ExCeL trialled eight DuroSite
Series 150W LED High Bay lights
from Dialight. These replaced 400W
sodium lamps on a one-for-one basis
and delivered more than double the
lighting level taking the measured
lux from 100 to 220. This led to the
installation being extended to a total
of 194 LED High Bay lights.

Replacing sodium lamps with
LED High Bays ExCeL will potentially
save close to 700kW of energy per
day and, as the LED High Bays carry
Dialight’s 5-year warranty, costs for
maintenance will also be reduced.

The retrofit of LEDs has now been
extended to include the canopied
entrance to the conference centre.
