Form Factor & Design Profile
Engineered specifically for commercial stairwells and hallways, the 4ft surface-mount luminaire combines a durable powder-coated metal body with a contoured ribbed polycarbonate diffuser to deliver wide vertical and horizontal light distribution (125.3° vertical / 107.7° horizontal spread). Sliding switches on the internal driver and chassis allow installers to tailor lumen output and color temperature on-site.
Smart & Control Features
The UltraLED Ultrasonic Stairwell luminaire features a factory-installed ultrasonic bilevel motion sensor for high-resolution motion detection in enclosed stairwells and corridors:
- 0–10V Continuous Dimming (Standard): Dims smoothly down to 10% on standard 0–10V low-voltage control circuits.
- Trimpot #1 (Detection Range & Sensitivity): Left trimpot adjusts motion detection sensitivity across three settings: low, medium, and high.
- Trimpot #2 (Time Delay): Right trimpot sets the hold time that the fixture remains at 100% output after motion stops to 1 minute, 5 minutes, or 20 minutes.
- DIP Switches (Bilevel Dimming Level): Dual DIP switches configure the standby dimming level after the time delay expires to Off (Off/Off), 10% (Off/On), 25% (On/Off), or 50% (On/On) until motion is detected again.
- Integrated Test Mode Button: Sets the time delay to 5 seconds and runs for 5 minutes (indicated by 2 LED flashes at start and 3 LED flashes upon completion) to verify sensitivity and dimming levels. Upon initial power-up, the sensor turns on to 100% and dims to Off after 20 seconds before entering programmed operation.
Electrical
Powered by a constant current driver operating on 120–277V AC. Delivers high electrical efficiency with a Power Factor >90% (>0.90) and Total Harmonic Distortion (THD) <20%. Includes 0–10V dimming down to 10%.
