THE SITUATION
Looking to improve street lighting in its Downtown District, San Diego
officials conducted lighting preference surveys of more than 100
residents and five key stakeholder groups that oversee the city’s
maintenance assessments.
THE SOLUTION
LED street lighting was favored after the study indicated broad-spectrum
lighting was preferred by residents and business owners. Wireless lighting
controls were chosen for additional benets and savings.

Outdoor Wireless Control System, will replace
approximately 3,000 high pressure sodium lamps in a move expected
to save the city of San Diego upwards of $254,000 annually—likely even
more when incorporating available dimming schedule features.
“GE worked with us to develop the perfect, functional fixture for our
city with the ideal light output. GE added a band to reduce the uplight
and incorporated a frosted lens per our residents’ request. Adding in
the adaptive controls took the solution a step further. It is the most
beautiful light.”
