Construction

IES Classification

The Type IV distribution (also known as a Forward Throw) is especially suited for mounting on the sides of buildings and walls, and for illuminating the perimeter of parking areas. It produces a semicircular distribution with essentially the same candlepower at lateral angles from 90° to 270°.

Ambient Temperature

Suitable for use in up to 40°C (104°F)

Cold Weather Starting

The minimum starting temperature is -40°C (-40°F)

Thermal Management

Superior heat sinking with external Air-Flow fins

Lens

Tempered glass lens

Housing

Die-cast aluminum housing, lens frame and mounting arm

Mounting

Universal mounting arm compatible for hole spacing patterns from 1" to 5 1/2" center to center. Round Pole Adaptor plate included as a standard. Easy slide and lock to mount fixture with ease. Round pole diameter must be >4" to mount fixtures at 90° orientation.

Reflector

Specular vacuum-metallized polycarbonate

Gaskets

High-temperature silicone gaskets
