45 Watt Metal Halide LED Retrofit | 7425 Lumens | 175 Watt Replacement | 5000K | 100V-277V
45 Watt LED retrofit kit replaces metal halide bulbs inside your existing indoor or outdoor fixture. The retrofit kit is designed to replace Metal Halide bulbs and ballasts inside a sealed fixture. Active Cooling keeps this retrofit kit working for a very long time. This retrofit works well with existing motion sensors and photocells. It is easy to install - like doing a Metal Halide bulb and ballast replacement. You should also remove the fixture reflector and socket, as they will not be needed.

Product Overview
This 45 Watt Metal Halide LED Retrofit is designed for direct replacement of 175 Watt metal halide lamps in legacy fixtures. It delivers 7425 lumens at 5000K, providing a neutral white light suitable for a range of retrofit applications. The compact form factor and universal 100V-277V input make it compatible with most commercial and industrial fixture housings.
Typical use cases include energy upgrade projects and maintenance-driven lighting upgrades in facilities seeking to reduce operating costs and improve reliability. The retrofit kit is commonly installed in canopy, area, and site lighting fixtures where metal halide lamps are being phased out.
Core Performance and Output
This retrofit kit outputs 7425 lumens at 45 watts, achieving an efficacy of 165 lumens per watt. The 120° beam angle provides wide, even coverage suitable for open fixture types. Color temperature is fixed at 5000K, supporting visibility and color rendering in commercial environments. Power factor exceeds 0.90, and total harmonic distortion is below 15%.
At lower mounting heights, output may be excessive for small enclosures or confined spaces. Uniformity can be affected if installed in fixtures with restrictive optics or deep housings not designed for wide beam sources.
Adjustability and Control Options
The retrofit kit is available with optional dimming capability, allowing integration with compatible 0-10V dimming controls. The standard beam angle is 120°, with no field-adjustable optics. The kit is designed for fixed orientation within the host fixture, with no tilt or rotation adjustment.
Control options are limited to dimming; advanced controls such as occupancy or daylight sensors require external integration.
Longevity and Reliability
The LED array is rated for 100,000 hours (L70), with the driver specified for 50,000 hours of operation. Thermal management is passive, relying on the aluminum heat sink for consistent performance in typical retrofit environments. The kit is designed for continuous operation in ambient temperatures common to canopy and site lighting applications.
Reliability is supported by solid-state construction and ETL certification. Long-term performance depends on proper installation and fixture compatibility.
Build Quality and Physical Characteristics
The retrofit kit measures 4.75 inches square by 1.9 inches high and weighs 4 pounds. The housing is constructed from aluminum for heat dissipation and durability. The design supports surface mounting within existing fixture housings.
All components are rated for indoor or covered outdoor use when installed in a suitable enclosure. The kit is not intended for direct exposure to weather unless the host fixture provides adequate protection.
Where This Product Fits Best
This retrofit kit is intended for use in commercial and municipal environments where legacy metal halide fixtures are being upgraded for energy efficiency and reduced maintenance. It is most often deployed in projects where fixture replacement is impractical or cost-prohibitive.
- 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
Environments with covered or enclosed fixtures, such as canopies, parking structures, and site lighting, are typical. The kit is suitable for indoor or protected outdoor use where the host fixture shields it from direct weather.
Installation and Long-Term Use
Installation requires removal of the existing lamp and ballast, with direct wiring to line voltage. The compact size allows fitment in most standard metal halide fixture housings. Surface mounting hardware is included for secure attachment inside the fixture.
Long-term use is supported by passive cooling and solid-state design. Routine inspection of the host fixture and electrical connections is recommended to maintain performance. The retrofit kit is not suitable for fixtures with limited ventilation or where ambient temperatures exceed standard commercial ranges.
How This Fixture Is Commonly Used
This retrofit kit is typically installed at mounting heights ranging from 10 to 20 feet, depending on the application and fixture type. Spacing and layout patterns follow the original fixture grid, with one-for-one replacement being standard practice in most retrofit projects.
Higher output allows for reduced fixture count in some cases, but may increase glare if installed in low or confined spaces. Final layout should consider the host fixture?s optical characteristics and the target light levels for the space.
Safety, Certifications, and Warranty
This retrofit kit is ETL certified and rebate eligible. All components meet applicable safety and performance standards for retrofit lighting products. The kit is designed for use in covered or enclosed fixtures as specified by the manufacturer.
Warranty coverage is provided for both the LED array and driver, supporting long-term reliability in retrofit applications. Refer to the product documentation for warranty terms and claim procedures.
