The ILP CV4-4L-U-40-FRAL Cavern stairwell LED light is a high-performance fixture designed to illuminate interior stairwells and access corridors with energy-efficient, long-life LED technology. This 4-foot model delivers 4109 lumens at 4000K with a high efficacy of about 151 lm/W and a CRI greater than 80, providing clear, natural-looking light that helps improve visibility and safety in low-light areas. The frosted acrylic lens is impact resistant, helping maintain light quality in demanding environments, while the housing options—Cavern (CV) and Cavern Lite (CVL)—offer different construction choices to suit installation needs and durability requirements. The unit is available in a standard white finish with optional custom colors and can be mounted on walls or ceilings, giving flexibility for retrofit projects that aim to cover existing footprints without repainting.

Key design features include a compact 7.5-inch width and compatibility with 2-foot or 4-foot lengths, enabling straightforward integration into stairwells and corridors. The fixture supports 0–10V dimming (100% to 10%), enabling energy savings and lighting control in response to occupancy or daylight conditions. It operates on universal voltage (120–277V), simplifying electrical planning across different facilities, and is ETL listed for damp and dry locations, indicating suitability for a range of indoor environments. The unit also offers an optional integral emergency battery backup for continued illumination during power interruptions and an ultrasonic sensor option to maximize sensing range for occupancy-based lighting control. It carries a 5-year warranty and is DesignLights Consortium Premium qualified, reflecting its energy efficiency and performance credentials.
