Smart & Control Features

The STRP4 strip light features a Class 2 dimming driver with an integrated 12VDC (30mA) auxiliary power supply supporting modular occupancy sensing and wireless building automation:

• 0–10V Continuous Dimming (Standard): Dims smoothly down to off on standard 0–10V low-voltage control circuits. Compatible with commercial dimmers and centralized building automation systems (BAS).
• Lightcloud Blue (Accessory): Compatible with field-installable sensors for Bluetooth mesh group control, scheduling, daylight harvesting, and automated occupancy sensing without a gateway or additional control wiring.

Compatible external sensors mount to the fixture using the Right Angle Arm Support (RAAS) and include passive infrared (PIR, max 40 ft mounting height) and microwave (MVS, max 50 ft mounting height) models — sold separately. Field adjustments for standard sensors can also be managed using an optional handheld remote control (sold separately).

Electrical

Powered by a Class 2 constant current driver operating on 120–277V AC at 50/60Hz (10.4–19.8W input power). Delivers high electrical efficiency with a Power Factor of 99.4% at 120V (95.1% at 277V) and Total Harmonic Distortion (THD) of 7.7% at 120V (8.7% at 277V). Integrated 1kV differential mode (DM) and 2kV common mode (CM) surge protection protects internal electronics against transient voltage spikes. Includes pre-wired 0–10V dimming leads and 12VDC auxiliary power.

Emergency Battery Backup: Available factory-configured on 4ft `/E` suffix models to provide standby illumination during a primary power failure (Battery Backup Light Loss Factor: 20% at 20W, 26.7% at 15W, 40% at 10W).
