34 / 38 / 45 Wattage Adjustable LED Vapor Tight Light | 4900 to 6500 Lumens | 4000K / 5000K Adjustable | 100-277V | 4 Foot
This 4-foot LED vapor tight fixture is a strong choice for demanding environments where dust, moisture, or water spray are present, thanks to its IP65 rating, sealed polycarbonate construction, and UL listing. Its selectable wattage (34/38/45W) and color temperature (4000K/5000K) allow adaptation to changing needs, while 0-10V dimming and a broad 120-degree beam angle support flexible, uniform illumination. With up to 145 lumens per watt and a 100,000-hour (L70) lifespan, it is well suited for warehouses, manufacturing, parking garages, loading docks, and food processing areas. Not intended for hazardous locations.

Product Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for a simple rectangular space using the selected LED fixture. Enter your room dimensions, mounting height, target foot-candles, light loss factor, and room/layout condition to generate a preliminary lighting layout. When IES photometry is available, workplane height and room reflectance controls are shown.
Project Inputs
Estimated Results
Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.
Room / Layout Condition: This field is used only when usable IES photometry is not available. In fallback mode, it acts as a simplified room utilization factor for reflectance, fixture distribution, racking, obstructions, and how much fixture light reaches the work area. Open / light-colored spaces use 0.90, typical warehouses or shops use 0.75, racked or obstructed spaces use 0.60, and dark or complex spaces use 0.45. When IES photometry is active, this field is hidden and the estimator uses the selected workplane height, LLF, and simplified reflectance adjustment instead.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data, selected workplane height, light loss factor, and simplified reflectance adjustment to estimate fixture count, average foot-candles, and visual light distribution. The reflectance adjustment is a conservative approximation and is not a full zonal-cavity, radiosity, or professional photometric room calculation. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room/layout condition, light loss factor, and beam angle.
Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces and should be used as a planning aid, not a final photometric lighting plan. Actual light levels may vary based on fixture optics, selected IES file, mounting conditions, workplane height, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements. Project-critical applications should be verified with a formal lighting plan.
This estimate is a starting point. Warehouses, industrial facilities, hazardous locations, sports areas, schools, healthcare spaces, public areas, and code-sensitive projects may require a reviewed lighting layout before purchase or installation.
Product Overview
This 4-foot LED vapor tight light is a linear fixture for wet and demanding indoor or covered locations. It has selectable 34W, 38W, and 45W output settings with selectable 4000K and 5000K color temperature.
The fixture supports surface mounting or V-hook mounting. Its IP65-rated polycarbonate housing and lens suit applications such as cold storage lighting, car wash lighting, utility room lighting, and washdown area lighting.
Core Performance and Output
Output ranges from 4,900 to 6,500 lumens at 145 lumens per watt. The 120-degree distribution provides broad light from the linear housing, with 80+ CRI for general task and circulation visibility.
The fixture operates on 100-277V, 50/60 Hz power and has a power factor above 0.90. It is listed as replacing a 175W metal halide fixture.
The 45W setting can be excessive where lower light levels are required. Mounting height, fixture spacing, surface reflectance, and required light levels affect layout uniformity.
Adjustability and Control Options
Field-selectable wattage settings are 34W, 38W, and 45W. Color temperature is selectable between 4000K and 5000K.
0-10V dimming is included. Dimming control wiring and control selection must match the project control design.
Longevity and Reliability
This fixture is rated for 100,000 hours L70 life. The long rated life supports installations where access for routine fixture replacement is limited.
The sealed IP65 construction helps protect internal components from dust and water exposure. Long-term performance still depends on proper mounting, wiring, and environmental conditions.
Build Quality and Physical Characteristics
The housing is polycarbonate with a polycarbonate lens. The fixture has a white finish and measures 47.5 inches long, 10.5 inches wide, and 4.5 inches high.
Fixture weight is 16.5 pounds. Surface mounting and V-hook mounting are supported, allowing the fixture to be fixed directly to a structure or suspended from suitable mounting points.
Where This Product Fits Best
This vapor tight fixture fits locations that need enclosed linear lighting with broad distribution and IP65 protection. The adjustable output is useful where installation conditions vary within the same facility type.
- cold storage lighting
- car wash lighting
- washdown area lighting
- utility room lighting
- parking garage lighting
- food processing lighting
Its polycarbonate housing and lens suit wet or dusty conditions associated with these applications. Final fixture placement should account for mounting method, service access, and target light levels.
Installation and Long-Term Use
Install this fixture using either the surface-mount method or V-hooks. Confirm that the mounting structure supports the 16.5-pound fixture weight and that supply voltage is within the 100-277V range.
Use the wattage and color temperature selections before final commissioning. For 0-10V dimming installations, connect the dimming leads according to the control design.
Maintain access for cleaning the polycarbonate lens and inspecting mounting hardware. Accumulated surface contamination can reduce delivered light over time.
How This Fixture Is Commonly Used
In cold storage lighting and utility room lighting, fixtures are commonly arranged in continuous rows or aligned with the room layout. Mounting height is determined by ceiling structure, required illumination, and access requirements.
For car wash lighting and washdown area lighting, fixture placement follows the equipment and service areas requiring light. The IP65 rating supports use where water and dust exposure are present.
Spacing varies with the selected wattage, mounting height, and required light levels. Higher output can reduce fixture count, but layout still determines uniformity across the area.
Safety, Certifications, and Warranty
This fixture is UL listed. It is rebate eligible.
The fixture has an IP65 rating. Warranty coverage is 5 years.
