The Evolve™ LED Medium Cobrahead luminaire combines over 100 years of street lighting experience with over a decade in designing breakthrough LED systems. This system features an advanced LED optical system that provides improved horizontal and vertical uniformity, reduced glare and improved lighting control. The contoured cobrahead-shape housing closely resembles existing fixtures in the field, and incorporates a heat sink fin design that not only provides excellent thermal management for extended LED life, but also allows for water run-off to minimize the build-up of dirt on the exterior of the fixture. The heat sink design and GE technology offer thermal heat management at the LED junction temperature – regardless of the temperature of the heat sink.

Named Best-in-Class by the U.S. Department of Energy in the Next Generation Luminaires™ Design Competition, the Evolve LED Medium Cobrahead can yield up to a 50-percent reduction in system energy compared with standard HID systems, depending on roadway applications. Additionally, this reliable system offers more than 11 years of service life to significantly reduce maintenance frequency and expense, based on a 50,000 hour life and 12 hours of operation per day.
