Description
LA Lighting CIT400 Series LED Vapor Tight High Bay — Fully Enclosed Industrial Luminaire
The LA Lighting CIT400 series is a fully enclosed LED vapor tight high bay engineered for industrial facilities where moisture, dust, and washdown conditions require sealed lighting equipment. The series provides high-output illumination with lumen packages of 16,000 or 24,000 lumens and color temperatures of 4000K or 5000K. Each fixture operates on a universal 120–277V driver with standard 0–10V dimming for compatibility with commercial lighting control systems.
The enclosure features a corrosion-resistant fiberglass housing, stainless steel latches, and a poured-in-place polyurethane gasket that creates a fully sealed luminaire. The fixture carries IP65, IP66, IP67, and NEMA 4X ratings, making it suitable for wet locations, washdown areas, and harsh industrial environments. An impact-resistant frosted acrylic lens distributes light evenly while protecting internal components.
Available Configurations
- CIT400-16-4L-DRFA-WL-DRDM-UNV-2/840 – 16,000 lumens, 4000K, standard ambient version
- CIT400-16-4L-DRFA-WL-DRDM-UNV-2/850 – 16,000 lumens, 5000K, standard ambient version
- CIT400-24-4L-DRFA-WL-DRDM-UNV-2/840HT – 24,000 lumens, 4000K, high-ambient temperature version
- CIT400-24-4L-DRFA-WL-DRDM-UNV-2/850HT – 24,000 lumens, 5000K, high-ambient temperature version
These configurations allow designers and contractors to select the required lumen package and color temperature while maintaining the same sealed industrial housing and washdown-rated performance across the CIT400 platform.

Performance & Light Output
High-efficiency LEDs deliver up to 24,000 lumens with uniform distribution for high-bay industrial lighting. Multiple lumen packages allow lighting designers to match illumination levels to ceiling height and facility requirements while maintaining long service life.
Electrical & Controls
The CIT400 operates on a universal 120–277V input and includes a standard 0–10V dimming driver for integration with commercial lighting control systems. Optional accessories such as motion sensors, emergency battery packs, and control-ready drivers can be configured depending on project requirements.
Construction & Durability
The fiberglass housing resists corrosion and chemical exposure, while stainless steel latches secure the lens assembly. The poured polyurethane gasket forms a tight seal that protects the internal LED system from dust, moisture, and washdown conditions.
Installation & Mounting
Integrated stainless steel mounting tabs support installation using V-hooks, chain suspension, cable suspension systems, or ceiling mount hangers. Optional watertight hubs, lens tethers, and mounting accessories are available depending on the project configuration.
Included
