Pulsar provided their Eco-range solution for Stansted Airport’s Diamond Hangar and consequently reduced its annual running costs by 85% and increased its light levels by 2.9x.
Requiring high levels of light every day all year round, this busy commercial aircraft hangar formerly had 384 x 400W High Pressure Sodium (Son) fittings burning for 3,640 hours per year.
This installation had a total wattage of 169 kW and consumed 615,000 kWh of electricity per year, generating an annual bill in excess of £75,000 for lighting alone.
The short lifespan of these high intensity lamps also resulted in an extra £3,000 per year in additional maintenance costs.
The Pulsar Eco-range solution has made a huge difference to the operation of the hangar. The new installation replaced the original 384 units with just 96 x 260W fixtures and greatly improved the floor lux levels from under 100 lux to a much brighter 250 lux.
Combined, these results hit the operator’s key requirements of removing maintenance costs while improving the overall lighting.
The new installation of high efficiency LED high bay lights creates a total wattage of just 25 kW and consumes only 90,084 kWh per year - an 85% reduction.
immediately this saves Diamond Hangar £64,754 in energy costs, and the long fixture lifespan eliminates maintenance requirements for at least 19 years if used 10 hours per day all year round.
By asking Pulsar to retrofit the Hangar with a high quality UK made LED lighting solution, the site’s operators have now been able to increase productivity, reduce running costs, and eliminate downtime due to lighting maintenance.
