Careful thermal management of the overall system

The LED lighting plan on London's Tower Bridge was unveiled earlier this year when GE, along with London 2012 sustainability partner EDF Energy, entered a public-private finance deal with Mayor Boris Johnson and the City of London Corporation to install a new energy-efficient lighting system on the Tower Bridge.

Careful thermal management of the overall system and drivers gives the BayLight a L70 rated life of over 60,000 hours at 40 degrees C and over 100,000 hours at 25 degrees C. With an IP66 Rating for the LED panel, the BayLight is certified for damp location. Furthermore, the BayLight contains no mercury or lead.

The optional integrated occupancy sensor further enhances the energy savings delivered by the BayLight. Unlike linear fluorescent lamps that tend to lose light output at lower operating temperatures, the BayLight's performance is enhanced at lower operating temperatures. At these lower ambient temperature ranges, the LED light output of the BayLight can increase by up to 6% while dramatically extending its rated life.
