JR Beam Profile Selection Guide
JR secondary optics contribute to safe worksite lighting.
Solid-state technology provides an excellent opportunity to deliver light on target surfaces effectively. Combining LEDs with secondary optics shapes the light output to increase the amount of usable light. An external lens protects the optics inside the JR. Optics offer flexibility during lighting design and application, reducing installation and operation costs.
Wide Beam
The wide beam version of the JR fixture distributes light in a 360° circular pattern and has an overall beam angle of approximately 140°. It's a well-rounded option for instances without a defined need for specific illumination shapes. Some typical applications are low bay, pole top, ceiling mount, small area flood, and confined spaces.

IESNA Street Type 1
The T1 optic distributes light in a narrow, symmetric pattern. The light shape is approximately 130° x 20°. Some typical applications are industrial walkways, conveyor belts, paths, aisles, and facility perimeters.

IESNA Street Type 2
The T2 optic distributes light in a narrow asymmetric pattern. The light shape is approximately of 160° x 25° with a 15° forward throw. Some typical applications are industrial walkways, stairs, platforms, and conveyor belts.

IESNA Street Type 3
The T3 optic distributes light in a wide asymmetric pattern. The light shape is approximately 160° x 50° with a 30° forward throw. Some typical applications include wall packs and door lights. Using the JR-T3 model on the interior perimeter walls, customers can reduce reliance on ceiling-mounted lights frequently blocked by equipment.

IESNA Street Type 5
The T5 optic distributes light in a symmetric circular pattern. The light shape produces a circular 360° distribution at a 140° beam angle, equally distributing illumination in all directions of the target area. Some typical applications are low bay, pole top, ceiling mount, small area flood, and confined spaces.
