Product Features
From local to major roadways, the GE Evolve™ LED Roadway Scalable Cobrahead fixtures are changing the way you
light your lanes. Preserving the aesthetic look of traditional roadway Cobrahead fixtures, GE balances the technical needs
of a sophisticated LED system with the functional demands of an outdoor fixture facing extreme weather hazards. GE’s
advanced LED optical design offers hundreds of photometric options to meet your precise lighting requirements, while
delivering reduced glare and improved light control. The refined thermal management system incorporates a sleek and
robust heat sink directly into the fixture to ensure maximum heat transfer and long LED life.
The GE Evolve LED Roadway Scalable Cobrahead offers more than 11 years of reliable service life to significantly
reduce maintenance frequency and expense, based on a 50,000 hour life and 12 hours of operation per day.
