155 / 185 / 200 Wattage Adjustable LED Vapor Tight Light | 24800 to 32000 Lumens | 3500K / 4000K / 5000K Adjustable | 100-277V | 4 Foot

Product Overview

This 4-foot LED vapor tight fixture delivers field-adjustable output from 24,800 to 32,000 lumens across three wattage settings: 155W, 185W, and 200W. Color temperature is also adjustable on-site, with 3500K, 4000K, and 5000K options available. The fixture operates at 160 lumens per watt and serves as a direct replacement for 400-watt metal halide systems.

The housing is polycarbonate with a polycarbonate lens, finished in white. Overall dimensions are 47.5 inches long by 10.5 inches wide by 4.5 inches high, with a weight of 16.5 pounds. Standard voltage range is 100-277V, with an optional 277-480V configuration available. The fixture supports 0-10V dimming.

Rated life is 100,000 hours at L70. CRI is 80+. Beam angle is 120 degrees. Power factor exceeds 0.90, and the fixture operates on 50-60Hz input.

Where This Product Fits Best

This vapor tight fixture is built for wet, dusty, or corrosive environments where enclosed, sealed construction is required. Typical locations include food processing facilities, cold storage, wash-down areas, parking structures, loading docks, and industrial corridors. The IP65 rating allows exposure to water jets and dust without compromising internal components.

The IK10 impact rating supports installation in areas subject to physical contact from equipment, carts, or personnel traffic. At 16.5 pounds and just under 4 feet in length, this fixture fits standard ceiling grid layouts and suspended mounting configurations in industrial and commercial spaces.

Performance and Functional Considerations

Output ranges from 24,800 lumens at 155W up to 32,000 lumens at 200W. This range covers applications where a single fixture class needs to address varying ceiling heights or task lighting demands. At 160 lumens per watt, efficiency remains consistent across all wattage settings.

The three color temperature options allow alignment with facility lighting standards or tenant requirements. The 3500K setting provides warmer output suited to retail-adjacent or office-adjacent areas, while 5000K delivers cooler, higher-contrast light typical in industrial environments. The 4000K setting offers a middle ground used across general commercial applications.

Dimming via 0-10V allows integration with building automation or manual dimming controls where output reduction is needed for daylight harvesting or occupancy-based strategies.

Installation and Long-Term Use

Mounting options include surface mount and V-hook suspension. The polycarbonate housing and lens reduce weight compared to glass or metal alternatives and resist cracking under impact. The 120-degree beam angle distributes light broadly, reducing the need for supplemental fixtures in open-plan layouts.

The 100-277V standard input covers most commercial and light industrial panels. For facilities operating at higher service voltages, the optional 277-480V configuration is available. Power factor above 0.90 supports compliance with utility harmonic requirements and minimizes reactive load on branch circuits.

With a rated life of 100,000 hours, this fixture is designed for extended service intervals. The sealed IP65 enclosure eliminates routine cleaning of internal optics in dusty or wet environments.

How This Fixture Is Commonly Used

Wattage and color temperature are set during or after installation using onboard selectors. Facilities with mixed-use zones often set different output levels based on task requirements or ceiling height variation across the building. Once adjusted, no further interaction is required under normal operation.

Where 0-10V dimming is connected, the fixture responds to control signals from occupancy sensors, timers, or building management systems. In standalone applications, the fixture operates at the selected wattage without additional control hardware.

Maintenance personnel typically interact with this fixture only during relamping of adjacent legacy systems or when reconfiguring space layouts. The sealed housing does not require lens removal or internal access under normal service conditions.

Safety, Certifications, and Warranty

This fixture is UL listed and rebate eligible. The IP65 rating allows direct exposure to water spray and airborne dust. The IK10 rating allows the fixture to withstand significant mechanical impact without damage to the housing or lens.

LED Lighting Supply provides a 5-year warranty on this fixture.
