At 130W: 17,706 lm.
At 100W: 14,085 lm.
All output levels available across all three CCT selections. CRI: 80+. Beam angle: 55° / 85° / 105° — field-selectable. Rated life: 100,000 hours per IES LM-80 / TM-21 (L70). Color uniformity per ANSI C78.377-2017.

Lens & Optics

The RBAY22S features a field-selectable beam angle system with three settings: 55° (narrow, for high mounting heights), 85° (default, general industrial), and 105° (wide, for lower mounting or broader coverage). Lens material: polycarbonate. Optic selection is made on-site without additional accessories. The selectable beam angle differentiates the RBAY22 platform from fixed-optic competitors and enables precise IES photometric matching for lighting design submittals.
