Form Factor & Design Profile

The RAB TOMO-4WM linear fixture is designed specifically for architectural surface wall-mount applications, integrating a dedicated heavy-gauge backplate that secures flush to commercial wall surfaces. Formed from cold rolled carbon steel (SPCC) with an impact-resistant diffused PMMA lens, its compact 4ft geometric housing delivers soft forward-throw and vertical surface illumination for stairwells, corridors, and commercial restroom vanities.

Smart & Control Features

The RAB TOMO-4WM linear luminaire features flexible control integration supporting standalone dimming and modular wireless automation:

• 0–10V Continuous Dimming (Standard): Dims smoothly down to 5% on standard 0–10V low-voltage control circuits. Compatible with commercial architectural dimmers and centralized building automation systems (BAS).
• Lightcloud & Lightcloud Blue Wireless Control (Accessory): Compatible with field-installable Lightcloud and Lightcloud Blue screw-in sensor modules for Bluetooth mesh group control, automated scheduling, daylight harvesting, and motion detection without requiring an external gateway or hub.

Compatible plug-and-play sensors include PIR and microwave motion sensors (max 50 ft mounting height, 50 ft detection diameter) — sold separately. Field adjustments can also be managed using the optional handheld remote control (catalog # TOMO-REMOTE, sold separately).

Electrical

Powered by a Class 2, Class P constant current driver operating on 120–277V AC at 50/60Hz. Delivers high electrical efficiency with a Power Factor >0.89 (99.5% at 120V, 94.1% at 277V) and Total Harmonic Distortion (THD) <9.25% at 120V and 17.1% at 277V. Integrated 1kV to 2kV surge protection safeguards internal electronics against transient voltage spikes. Includes pre-wired 0–10V dimming leads.
