120 Watt Metal Halide LED Retrofit | 18600 Lumens | 400 Watt Replacement | 4000K or 5000K | 100V-277V or 277V-480V

Product Overview

This 120 Watt Metal Halide LED Retrofit is designed for direct replacement of 400 Watt metal halide lamps in existing fixtures. It delivers 18,600 lumens and is available in 4000K or 5000K color temperatures. The retrofit kit is suitable for a range of fixture retrofit and energy upgrade projects where maintaining the existing housing is preferred. Typical installations include high bay, low bay, and area lighting fixtures in commercial and industrial environments.

The compact form factor allows for installation in a variety of legacy fixture types, including enclosed and open luminaires. This retrofit is commonly used in facilities seeking to reduce maintenance and energy costs while upgrading to LED performance without a full fixture replacement.

Core Performance and Output

This retrofit kit provides 18,600 lumens at 120 watts, achieving an efficacy of 155 lumens per watt. The 120° beam angle supports wide, even distribution in most open fixture types. Power factor exceeds 0.90 and total harmonic distortion is below 15%, supporting stable operation on both 100-277V and 277-480V circuits.

Output is suitable for mounting heights typically associated with 400W metal halide lamps, generally ranging from 15 to 30 feet. Excessive output may occur if installed at lower mounting heights or in small enclosures, which can lead to glare or over-lighting. Uniformity may be reduced in fixtures with restrictive optics or deep reflectors.

Adjustability and Control Options

This retrofit kit is available with optional dimming capability, allowing for integration with compatible 0-10V dimming controls. The wide beam angle is fixed, matching the distribution of most legacy metal halide lamps. No field-adjustable optics are included.

Color temperature can be specified as either 4000K or 5000K at the time of order. The retrofit is compatible with occupancy sensors and daylight harvesting controls when installed with appropriate drivers and wiring.

Longevity and Reliability

The LED array is rated for 100,000 hours (L70), with the driver rated for 50,000 hours. This supports long-term operation in retrofit applications where access for maintenance may be limited. Thermal management is integrated into the design to maintain performance in enclosed fixtures.

Consistent lumen output and color stability are maintained over the rated life. The retrofit is designed for continuous operation in typical commercial and industrial environments.

Build Quality and Physical Characteristics

The retrofit kit measures 6.1 inches in length, 5.2 inches in width, and 2.75 inches in height, with a weight of 4.5 lbs. The compact size allows for installation in a wide range of fixture housings, including high bays, low bays, and area lights.

Construction materials are selected for durability and thermal performance. The retrofit is ETL certified and meets requirements for rebate eligibility. All components are rated for use in dry and damp locations as permitted by the existing fixture housing.

Where This Product Fits Best

This retrofit kit is intended for commercial and industrial environments where existing fixtures are being upgraded to LED technology. It is most often used in projects where fixture replacement is not practical or where maintaining the original fixture appearance is required.

• fixture retrofit projects
• energy upgrade projects
• legacy fixture conversion
• maintenance-driven lighting upgrades
• tenant improvement projects
• warehouse lighting retrofit
• parking lot lighting retrofit
• municipal retrofit programs

Environmental suitability is determined by the existing fixture housing. The retrofit is compatible with both open and enclosed fixtures rated for LED retrofits. Not intended for use in hazardous or high-temperature environments unless the host fixture is rated accordingly.

Installation and Long-Term Use

Installation involves removal of the legacy lamp and ballast, followed by direct wiring of the retrofit kit to line voltage. The compact design supports installation in most standard metal halide, high bay, and area light housings. Mounting hardware is included for secure attachment within the fixture.

Long-term maintenance requirements are minimal compared to legacy lamps. Periodic inspection of electrical connections and fixture integrity is recommended. The retrofit is designed for use in both vertical and horizontal lamp positions, but always confirm fit and clearance within the host fixture before installation.

How This Fixture Is Commonly Used

This retrofit is typically installed at mounting heights between 15 and 30 feet, matching the original application of 400W metal halide lamps. Spacing and layout patterns are determined by the existing fixture grid and desired light levels. In warehouse and area lighting retrofits, fixture-for-fixture replacement is standard practice.

Higher output reduces the number of fixtures required in some layouts, but may increase glare if not properly shielded or if installed at low mounting heights. Always verify compatibility with the existing fixture and application before proceeding with installation.

Safety, Certifications, and Warranty

This retrofit kit is ETL certified and meets requirements for utility rebate programs. All electrical and safety standards applicable to retrofit installations are met. The product is covered by a manufacturer?s warranty; refer to documentation for terms and coverage details.

Installation must comply with local electrical codes and the requirements of the existing fixture. Only qualified personnel should perform retrofit installations.

Frequently Asked Questions

Q: What is the recommended mounting height for this retrofit kit?

A: Typical mounting heights range from 15 to 30 feet, matching the original use of 400W metal halide lamps.

Q: Can this retrofit be used in enclosed fixtures?

A: Yes, it is suitable for use in both open and enclosed fixtures, provided the fixture is rated for LED retrofits.

Q: Is dimming available with this retrofit kit?

A: Dimming is optional and requires compatible 0-10V controls and wiring.
