Lens & Optics

The Beam Selectable optical system provides field-adjustable beam distributions on the job site without tools or rewiring. The built-in beam selection switch allows installers to instantly toggle between three distinct distributions:

• 60° Narrow Optic: Concentrates beam distribution for narrow racking aisles, focused task areas, and elevated mounting heights.
• 80° Medium Optic: Delivers balanced distribution for standard warehouse floors.
• 100° Wide Optic: Delivers broad, uniform beam distribution for open warehouse floors, staging areas, and general open-ceiling commercial layouts.

Optional aluminum reflectors, polycarbonate shades, and bottom diffusers are available separately (see Installation & Mounting).

Smart & Control Features

The 65-1521 supports modular sensing and automated facility lighting control:

• 0–10V Continuous Dimming (Standard): Standard dimming control compatible with commercial 0–10V dimmers.
• Sensor Compatibility (Accessory): Accepts field-installable PIR and microwave occupancy sensors via the integrated sensor port.

Compatible plug-and-play sensors include the 86-238 (PIR) and 86-239 (Microwave) — sold separately. Field sensor adjustments can also be managed using an optional handheld wireless programming remote (catalog # 86-237, sold separately).

Electrical

Powered by a constant current driver operating on 120-347V AC at 50/60Hz. Delivers high electrical efficiency with a Power Factor >0.90 and Total Harmonic Distortion (THD) <20%. Integrated 6kV surge protection protects internal electronics against transient voltage spikes. Includes pre-wired 0–10V dimming leads. RoHS compliant.
