Evolve LED Cobra Head with Current Gen Optics - ERL Series

Evolve LED Cobra Head with Current Gen Optics - ERL Series

The Evolve® LED Roadway Luminaire is optimized for customers requiring a LED solution for local, collector and major roadways. The unique reflective optics are designed to optimize application efficiency, minimize glare, and 'shape' the light to where you want the light to go. The modern design incorporates the heat sink directly into the unit for heat transfer to prolong LED life. This reliable unit has a 100,000 hour design life, significantly reducing maintenance needs and expense over the life of the fixture. This efficient solution lowers energy consumption compared to traditional HID fixture for additional operating cost savings.
