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

Product Overview

This is a 4-foot, wattage and color adjustable LED vapor tight fixture designed for demanding environments where moisture, dust, and impact resistance are required. The fixture supports 155, 185, or 200 watt operation, delivering up to 32,000 lumens. Typical use cases include washdown areas, parking garages, and cold storage spaces where durability and consistent performance are critical. The fixture is suitable for mounting heights commonly found in utility rooms and covered parking structures.

Designed as a direct replacement for 400W metal halide vapor tight fixtures, this unit provides a sealed, impact-resistant solution for both new construction and retrofit projects. The polycarbonate housing and lens, along with IP65 and IK10 ratings, support installation in locations exposed to water spray, humidity, and physical contact.

Core Performance and Output

This fixture offers selectable output at 155W, 185W, or 200W, producing 24,800 to 32,000 lumens at 160 lumens per watt. The 120° beam angle provides wide, uniform coverage suitable for open areas and linear layouts. Color temperature can be set to 3500K, 4000K, or 5000K to match application requirements or existing lighting.

0-10V dimming is standard, supporting integration with common lighting controls. At lower mounting heights, the high output may require wider spacing to avoid excessive brightness. Uniformity may decrease if installed at heights above 18 feet without careful layout planning.

Adjustability and Control Options

Wattage and color temperature are field adjustable, allowing adaptation to changing requirements or phased upgrades. The fixture supports 0-10V dimming for occupancy or daylight control integration. Adjustments are made via onboard switches, accessible during installation or maintenance.

This flexibility supports both initial commissioning and future changes in use or lighting standards. No onboard motion sensor is included; external controls must be specified if required.

Longevity and Reliability

The fixture is rated for 100,000 hours (L70), supporting long-term operation in environments with frequent cleaning or exposure to moisture. The polycarbonate housing and lens resist impact and chemical exposure typical in washdown and parking applications.

All components are sealed against dust and water ingress. The fixture maintains performance in ambient temperatures common to parking garages, cold storage, and utility rooms. Routine cleaning does not compromise the enclosure integrity.

Build Quality and Physical Characteristics

The housing and lens are constructed from polycarbonate, providing IK10 impact resistance and supporting use in areas with potential for physical contact or vandalism. The fixture measures 47.5 inches long, 10.5 inches wide, and 4.5 inches high, with a weight of 16.5 lbs.

IP65 rating ensures protection against water jets and dust. The fixture is finished in white and includes both surface and V-hook mounting options. All hardware is corrosion resistant for use in damp or wet locations.

Where This Product Fits Best

This fixture is designed for environments requiring sealed, impact-resistant lighting with high output and flexible installation. It is commonly used in:

• washdown area lighting
• parking garage lighting
• cold storage lighting
• utility room lighting
• food processing lighting
• car wash lighting
• stairwell lighting
• outdoor covered walkway lighting

Enclosure and lens resist water, dust, and impact. Suitable for locations with routine cleaning, humidity, or exposure to the elements. Not intended for hazardous locations or areas requiring explosion proof certification.

Installation and Long-Term Use

The fixture supports both surface and V-hook mounting. All mounting hardware is included for standard installations. The 4-foot form factor allows direct replacement of legacy vapor tight fixtures without major modifications.

Wiring is accessible via sealed entry points. The fixture operates on 100-277V input; 277-480V is available as an option. Routine maintenance is limited to cleaning the lens and verifying enclosure seals. No relamping is required over the rated life.

How This Fixture Is Commonly Used

Typical mounting heights range from 10 to 18 feet, depending on output setting and application. Fixtures are spaced to provide uniform coverage, with wider spacing possible at higher wattage settings. Linear layouts are common in parking garages and washdown corridors.

In food processing and car wash applications, fixtures are installed to avoid direct spray on wiring entries. Higher output settings reduce fixture count but may increase glare if installed at low mounting heights.

Safety, Certifications, and Warranty

This fixture is UL listed and meets IP65 and IK10 requirements. All components are rated for use in wet locations. The product is eligible for utility rebates where applicable.

A 5-year warranty covers all components. No special maintenance is required beyond routine cleaning and inspection of seals. All safety and certification markings are present on the fixture label.
