PROJECT CASE STUDY

Gatwick Airport

Opened as an aerodrome in the late 1920s, it started taking commercial flights in 1933. Now, with over 46,000,000 passengers travelling through it every year, LGW is the second busiest single-runway in the world

The challenge

There were two main reasons LGW decided to move from sodium to LED lighting:

  • A number of their stands weren’t meeting EASA legislation.
  • They wanted to reduce their energy use by 20% compared to 1990’s levels. So, they came straight to Midstream Lighting to help them meet these challenges.

Our solution

After a complete review of LGW’s current lighting facilities, we put our internal Design Team on the case. The solution they came up with was to upgrade all sodium apron lighting to our flagship Titan Series – with over 560 LED floodlights being installed. This has made LGW the first major European airport to have a fully Led-lit and EASA-compliant apron. And more importantly, the airport is now safer for staff and passengers, it’s more secure, and with less downtime runs more smoothly.
