34 / 38 / 45 Wattage Adjustable LED Vapor Tight Light | 4900 to 6500 Lumens | 3500K / 4000K / 5000K Adjustable | 100-277V | 4 Foot

Product Overview

This 4-foot LED vapor tight fixture delivers 4900 to 6500 lumens with field-adjustable wattage settings of 34, 38, or 45 watts. The fixture replaces 175-watt metal halide systems and operates on 100-277V input. A polycarbonate housing and lens provide the durability expected in wet or washdown environments.

Color temperature is adjustable between 3500K, 4000K, and 5000K, allowing the same fixture to be configured for different visual requirements. The 120-degree beam angle distributes light broadly across the coverage area. At 145 lumens per watt, this fixture maintains high efficiency across all wattage settings.

Dimensions are 47.5 inches long by 10.5 inches wide by 4.5 inches deep, with a weight of 16.5 pounds. The fixture ships in white and supports 0-10V dimming.

Where This Product Fits Best

The IP65 rating makes this fixture suitable for areas exposed to water spray, dust, and debris. Typical environments include food processing areas, cold storage facilities, car washes, parking garages, loading docks, and industrial washdown zones. The polycarbonate construction resists impact and chemical exposure better than glass alternatives in these applications.

The 4-foot form factor fits standard ceiling grid spacing and works well in corridors, mechanical rooms, and stairwells where linear coverage is needed. Surface mounting is standard, with V-hook mounting available for suspended installations.

Performance and Functional Considerations

Wattage adjustment allows output to be matched to the actual requirements of the space. The 34-watt setting produces 4900 lumens, the 38-watt setting produces 5400 lumens, and the 45-watt setting produces 6500 lumens. This adjustment is made at the fixture before or during installation.

Color temperature selection between 3500K, 4000K, and 5000K accommodates different task requirements and visual preferences. Warmer temperatures suit areas where a less clinical appearance is preferred, while cooler temperatures provide higher visual acuity for detailed work.

The 100,000-hour L70 lifespan represents the point at which output is projected to decline to 70 percent of initial lumens. CRI is rated at 80 or higher, which is adequate for general industrial and commercial tasks. Power factor exceeds 0.90.

Installation and Long-Term Use

The fixture mounts directly to ceiling surfaces using the standard mounting method or suspends from V-hooks where clearance or aesthetic considerations require it. The 100-277V input range covers standard commercial and industrial electrical systems without requiring voltage-specific variants. Frequency compatibility is 50-60Hz.

At 16.5 pounds, the fixture requires appropriate support but does not demand specialized structural reinforcement in most ceiling systems. The 0-10V dimming input allows integration with building automation systems or manual dimming controls where installed.

Polycarbonate housing and lens construction reduces breakage risk during installation and maintenance. The IP65 rating permits direct washdown cleaning in food service and processing environments without fixture damage.

How This Fixture Is Commonly Used

After installation, the wattage and color temperature settings remain fixed unless manually changed at the fixture. Facilities that standardize on a single configuration across a building typically set all fixtures identically during commissioning. In spaces with varying ceiling heights or task requirements, individual fixtures can be configured differently.

The 0-10V dimming capability allows output to be reduced below the selected wattage setting when connected to compatible controls. This is commonly used in areas with daylight contribution or during low-occupancy periods. Without dimming controls connected, the fixture operates at full output for the selected wattage.

In wet environments, maintenance personnel can wash down the fixture directly without removing it or protecting it from water exposure. The sealed housing prevents moisture ingress that would otherwise damage internal components.

Safety, Certifications, and Warranty

This fixture is UL listed and rebate eligible. The IP65 rating indicates protection against dust ingress and water jets from any direction. We back this fixture with a 5-year warranty.
