75 Watt Metal Halide LED Retrofit | 12375 Lumens | 5000K | 100-277V | 250 Watt Replacement

Product Overview

This 75 Watt LED retrofit kit is designed to replace 250 Watt metal halide bulbs and ballasts inside existing indoor or outdoor fixtures. It delivers 12,375 lumens at 5000K, providing a direct upgrade path for legacy metal halide systems.

The retrofit kit operates on 100-277V input and is compatible with both 50Hz and 60Hz electrical systems. It features active cooling to maintain long-term performance and reliability.

The kit is suitable for use in sealed fixtures. The reflector and socket from the original fixture should be removed during installation, as they are not required for LED operation.

Optional dimming is supported. The retrofit kit is compatible with existing motion sensors and photocells already installed in the fixture circuit.

Where This Product Fits Best

This retrofit kit is intended for facilities looking to upgrade from 250 Watt metal halide lamps to LED while retaining the existing fixture housing. It is suitable for both indoor and outdoor applications where sealed fixtures are present.

Common use cases include warehouses, manufacturing areas, distribution centers, and exterior site lighting where metal halide systems are currently installed. The kit is sized for fixtures that can accommodate its 6.1 inch by 5.2 inch by 2.75 inch dimensions.

It is appropriate for locations requiring a 5000K color temperature and a CRI of 75 or higher. The 120° beam angle supports general area lighting needs.

Facilities with voltage supplies between 100V and 277V can use this retrofit kit without modification.

Performance and Functional Considerations

The retrofit kit provides 165 lumens per watt, offering high output efficiency for energy-conscious operations. The 12,375 lumen output is designed to match or exceed the performance of the 250 Watt metal halide systems it replaces.

Active cooling extends the operational lifespan, with the driver rated for 50,000 hours and the LED module rated for 100,000 hours (L70). Power factor exceeds 0.90 and total harmonic distortion is below 15%.

The kit supports optional dimming for facilities that require adjustable light levels. It is compatible with existing motion sensors and photocells, allowing integration with current control strategies.

The 120° beam angle provides broad, even coverage suitable for most open-area lighting applications.

Installation and Long-Term Use

Installation involves removing the existing metal halide bulb, ballast, reflector, and socket from the fixture. The retrofit kit mounts in place of the original components and connects to the existing power supply.

The compact form factor (6.1 in L x 5.2 in W x 2.75 in H) and 4.5 lb weight allow for straightforward handling and mounting inside most standard fixture housings.

Active cooling maintains thermal performance over time, supporting long-term reliability in both indoor and outdoor environments. The retrofit kit is designed for use in sealed fixtures, protecting internal components from dust and moisture.

Routine maintenance requirements are minimal compared to legacy metal halide systems, with no lamp or ballast replacements needed during the rated service life.

How This Fixture Is Commonly Used

Once installed, this retrofit kit provides consistent, high-output lighting with a neutral white 5000K color temperature. You can rely on stable light levels without the warm-up or color shift associated with metal halide lamps.

If your facility uses dimming, the kit supports optional dimming control for adjusting light output as needed. Integration with existing motion sensors and photocells allows the fixture to operate as part of your current control system without additional changes.

Day-to-day, you will not need to replace lamps or ballasts. The active cooling system operates automatically, requiring no user intervention. The fixture maintains its output and color quality over its rated lifespan.

Physical access to the fixture is only needed for periodic inspection or cleaning, as the retrofit kit is designed for long-term, low-maintenance operation in sealed environments.
