re-imagining roadways

taking the science of light on the road

street-smart
from the start

Over a century ago, GE created the first streetlights, and we’ve been mastering the technology behind roadway fixtures ever
since. More than one hundred years and thousands of miles of street lighting later, our passion for innovation still burns bright.

In 1962, GE scientist Dr. Nick Holonyak Jr. invented the first visible LED, leading the way to the next generation of lighting
solutions. Today, we have applied our expertise in outdoor fixture and LED systems design to bring you our award-winning

GE Evolve

Building on a reputation for excellence that dates back to Edison’s first electric light bulb, GE brings a depth of expertise that’s
unsurpassed in the industry. From day one, we’ve been here, ready to work with you to provide a solution that helps save energy
while bringing greater aesthetics and overall cost savings to city streets and roadways. And you can count on GE to be there
as we continue to lead the lighting revolution.

LED Roadway Scalable Cobrahead (ERS) fixture.

industry experts pick GE as best-in-class

Our forward thinking has been recognized repeatedly by the industry. Most recently, GE’s Evolve ERS fixture was awarded

™

a Best-in-Class designation in the 2012 Next Generation Luminaires
the Roadway Lighting category. Sponsored by the U.S. Department of Energy (DOE), the Illuminating Engineering Society
of North America (IES), and the International Association of Lighting Designers (IALD), the NGL awards were created to
recognize excellence in energy-efficient LED commercial lighting unit design.

The Evolve ERS was also recognized for its pioneering design and technical excellence, winning the 2013 LIGHTFAIR
International Innovation Award category for Parking, Roadway and Area Lighting, and a 2012 Architectural SSL Product
Innovation Award (PIA).

optical design

aiming to please

GE uses an advanced reflective optic design that meets RP-8 recommended practices for luminance, illuminance and small target
visibility. This unique design ensures that Evolve ERS fixtures will deliver light control with significantly less waste than the other
optical technologies used by many of our competitors.

Evolve ERS fixtures have improved ratings for backlight, up-light and glare (BUG ratings) to direct more light on the road and not in
neighboring properties or in the eyes of nighttime drivers, meeting tight local ordinances and International Dark-Sky (IDA) requirements.

COMPETITION

Our unique reflective technology allows us to focus light
where it’s needed – on the road – with less glare.

The refractive technology design used by other
manufacturers typically results in more wasted light
trespass and glare for drivers.

minimizing glare

GE’s innovative reflective design only puts light where it is needed and minimizes direct view of the light source with
a non-pixilated appearance.

GE design recesses the LED array within the optic (or reflector) to limit visibility of the LEDs from the drivers’ field of view,
minimizing glare. Many competing optical designs use LED arrays with individual optics, making the entire array visible to the
driver, resulting in a pixilated appearance with higher levels of glare and increased light trespass.

GE’s unique reflective optic design delivers a non-pixilated light source with exceptional light control to provide low light trespass,

zero up-light and minimized glare.

why is luminance an important focus
of GE’s optical reflector design?

GE optical design provides outstanding overall
visibility while driving, offering reflector optics that
were designed with the driver in mind. This design only
puts necessary light at and above 45° angles, reducing
glare to the driver. GE provides consistent luminance
uniformity in the driver’s center field of view, while
many competing products have greater variation.
GE also ensures reduced glare at the critical angles,
improving small target visibility which allows drivers
to detect objects faster while driving. The uniformity
of light in the driver’s field of view improves the retina
image. Designing for the driver’s field of view with
consistent retina light levels provides excellent overall
visibility while driving.
