By switching to LED lights at a Canadian office, pharmaceutical giant GlaxSmithKline estimates it is saving $46,000 a year.
The lighting retrofit at its Mississauga, Ontario, office, involved switching from fixtures that used 26 watts an hour to new ones using nine watts an hour, said Terrence DeWolfe of GlaxoSmithKline, in a statement.
Because the LEDs operate cooler than the traditional lighting they replaced, the company expects to save money on cooling costs too.
DeWolfe said the fixtures should pay for themselves in about two years.
The retrofit was handled by CRS Electronics, which also did a retrofit at the Palace Pier condo tower in Toronto, which it claims to be the largest LED retrofit of a residential project in North America.
Other companies are switching to LED, as well.
For instance, Ford is conducting a retrofit of its lighting systems at its Detroit Campus facilities. New England Energy Management (NEEM) will retrofit or replace more than 50,000 light fixtures, which will include the addition of lighting control systems and daylight dimming controls for maximum efficiency.
