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. Standard voltage is 100-277V, with a 277-480V option available. The fixture measures 47.5 inches long by 10.5 inches wide by 4.5 inches high and weighs 16.5 pounds.

Where This Product Fits Best

This fixture is built for wet, dusty, and wash-down environments where sealed construction and impact resistance are required. The IP65 rating allows exposure to water jets and heavy dust accumulation without moisture ingress. The IK10 rating means the housing can withstand significant physical impact from tools, materials, or equipment contact.

Typical installations include food processing areas, cold storage facilities, parking structures, wash bays, manufacturing floors, and mechanical rooms. The 120-degree beam angle provides broad, even coverage suited to linear mounting runs in corridors, production lines, or storage aisles.

Performance and Functional Considerations

Wattage and color temperature adjustments are made at the fixture before or during installation. The three wattage positions allow output to be matched to actual foot-candle requirements without overshooting or undershooting target light levels. This is particularly useful when replacing metal halide systems where the original output was either excessive or marginal for the space.

The fixture accepts 0-10V dimming, which allows integration with building automation systems or manual dimmers for additional output control after installation. CRI is rated at 80+, which is appropriate for general industrial and commercial task lighting. Rated lifespan is 100,000 hours at L70.

Installation and Long-Term Use

Mounting options include surface mount as standard and V-hooks for suspended installations. The 16.5-pound weight is manageable for single-installer handling, though the 47.5-inch length may require support during ceiling attachment. Electrical connection operates at 50-60Hz with a power factor above 0.90.

The polycarbonate housing and lens resist chemical exposure and are easier to clean than glass or metal alternatives in wet or contaminated environments. Once installed, the sealed IP65 construction requires no gasket maintenance or periodic resealing under normal operating conditions.

How This Fixture Is Commonly Used

Once installed, the wattage and color temperature settings are typically left at their initial configuration. Facilities that operate across multiple shifts or seasonal conditions sometimes adjust output using the 0-10V dimming input rather than changing the wattage position. The 3500K setting is often selected for areas where warmer light is preferred, such as break rooms or entryways, while 5000K is more common in task-intensive production zones.

In spaces where ambient temperature, humidity, or airborne particulate levels fluctuate, the sealed polycarbonate construction reduces lens fogging and internal contamination. This keeps output consistent over time without the cleaning frequency required by open-frame fixtures.
