The ILP CV2-3L-U-40-FRAL Cavern Stairwell LED Light is a 2- or 4-foot surfaced luminaire designed to illuminate stairwells with efficient, long-life performance. It combines high-light output with energy efficiency, delivering 3,233 lumens at 22 watts and achieving up to 150 lumens per watt, resulting in meaningful energy savings for retrofit or new construction projects. The fixture uses a frosted acrylic lens that provides distribution with impact resistance, and a 3000–5000K color temperature range is available, with a CRI above 80 to support accurate color perception in stairwell environments. The design ensures compatibility with damp and dry locations, supported by ETL listing, and a 5-year warranty for added assurance.

Construction and features include a white standard finish with optional custom colors. The Cavern family offers a .060-inch aluminum body with cast aluminum end plates and a post-paint finish, while the Cavern Lite option uses a thinner .040-inch aluminum body with a baked-on enamel finish. The fixture is mountable on walls or ceilings, and its 7.5-inch width is intended to cover existing footprints without repainting, simplifying installation in facilities with established fixtures. An ultrasonic sensor option is available to extend sensing range for occupancy-based control, and the unit is designed for universal voltage operation from 120 to 277 V.

In terms of practical use, this luminaire is designed for stairwells and related egress areas where reliable visibility is essential. It supports 0–10V dimming (down to 10%), enabling integration with lighting controls for energy management. The fixture is DLC Premium qualified, indicating alignment with high-performance, energy-efficient criteria, and it carries an integral option for emergency battery backups for enhanced life-safety coverage where required. This product maintains standard maintenance expectations with a long-rated life, and its packaging is listed as per unit.
