LED LIGHTING CASE STUDY  

LED High Bay Lighting in
Refrigerated Storage Facility


SITUATION

Refrigerated warehouses operate continuously throughout
the year with their principal energy consumption used in
their cooling and lighting systems. Typical lighting fixtures,
based on high-pressure sodium and metal halide lamps, do
not have the capability for instant on/off and hence remain
on, even when no activity is occurring in the immediate area.
In an attempt to reduce kW and kWh, some operators have
experimented with occupancy sensored multi-lamp fluorescent
lighting fixtures with results confirming that light levels
have not been achieved, rapid switch on doesn’t occur
and a high rate of lamp and ballast failure.



PROJECT
Groom Energy engineers applied a newly introduced LED
based lighting system designed specifically for these
environments. This system produces higher levels and
quality of light than the existing systems, allows for
30 second interval occupancy sensing and switching,
and includes an embedded mesh network control and
reporting system. Light levels were set to the customer’s
desired levels alongside reducing operating hours from
8,760 per year to fewer than 1,000 hours per year.
The onboard software metering system confirms
these savings for all LED fixtures in the warehouse.
