IESNA LM-79 & IESNA LM-80 Testing

RAB LED luminaires and LED components have been tested by an independent laboratory in accordance with IESNA LM-79 and LM-80.

LED Characteristics

Lifespan

100,000-hour LED lifespan based on IES LM-80 results and TM-21 calculations

LEDs

Multi-chip, high-output, long-life LEDs

Color Consistency

7-step MacAdam Ellipse binning to achieve consistent fixture-to-fixture color

Color Stability

LED color temperature is warrantied to shift no more than 200K in CCT over a 5 year period

Color Uniformity

RAB's range of CCT (Correlated Color Temperature) follows the guidelines of the American National Standard for Specifications for the Chromaticity of Solid State Lighting (SSL) Products, ANSI C78.377-2017.

Construction

IES Classification

The Type III distribution is ideal for roadway, general parking and other area lighting applications where a larger pool of lighting is required. It has greater streetside (transverse) throw, allowing the light to project outward and fill the area.

IP Rating

Ingress Protection rating of IP66 for dust and water

Vibration Rating

Industry-leading 5G vibration rating per ANSI C136.31.

Ambient Temperature

SuitableFor use in 40°C (104°F) ambient temperatures

Cold Weather Starting

Minimum starting temperature is -40°C (-40°F)

Thermal Management

Superior thermal management design with external Air-Flow fins provides maximum operational life, even in high ambient temperature environments

Effective Projected Area

EPA = 0.75

Lens

Tempered glass lens

Housing

Die cast aluminum housing, lens frame and mounting arm
