Product Features

The Evolve™ LED Contemporary Twin Support Post Top (EPTC) offers energy efficiency and quality of light in your choice
of two distinct, modern styles. The advanced LED optical system provides improved horizontal and vertical uniformity,
reduced glare and improved lighting control. GE’s unique optical ring technology effectively aims the light where you
need it, while eliminating the unsightly shadow circles commonly seen under other LED post top fixtures.

The EPTC can yield up to a 60-percent reduction in system energy compared with standard HID systems, depending
on applications. This reliable system operates well in cold temperatures and offers more than 11 years of service life to
reduce maintenance frequency and expense, based on a 50,000 hour life at 12 hours of operation per day (L85 Rating).

Applications

• Roadway, site, area, and general lighting utilizing
advanced LED optical system providing high
uniformity, excellent vertical illuminance, reduced
offsite visibility, and reduced on-site glare.

Housing

• Base: die-cast aluminum housing.

• Top Upper Housing: one-piece spun aluminum,
available in two distinct contemporary designs.

• The upper fixture design incorporates the heat sink
directly into the unit ensuring maximum heat transfer
and long LED life.
