Product Overview
This 120 watt metal halide LED retrofit kit is designed to convert existing 400 watt metal halide fixtures to LED operation. It produces 18,600 lumens and is available in 4000K or 5000K color temperatures.
The kit supports fixture retrofit projects, legacy fixture conversion, and maintenance-driven lighting upgrades where the existing fixture housing remains in service. Input voltage is available in either 100V-277V or 277V-480V configurations.
Core Performance and Output
This retrofit delivers 155 lumens per watt with a 120 degree standard beam angle. The 18,600-lumen output is intended to replace a 400 watt metal halide light source.
Electrical performance includes 50/60 Hz operation, a power factor above 0.90, and THD below 15 percent. Output and beam distribution should be reviewed against the existing fixture geometry and required light levels before conversion.
Adjustability and Control Options
Optional dimming is available. The supplied data does not identify a dimming protocol or control type.
Color temperature selection is available in 4000K or 5000K. Voltage configuration must match the electrical system serving the existing fixture.
Longevity and Reliability
The driver is rated for 50,000 hours. LED performance is rated at 100,000 L70 hours.
Long-term retrofit performance depends on proper installation within an existing compatible fixture and selection of the correct voltage configuration.
Build Quality and Physical Characteristics
The retrofit assembly measures 6.1 inches long by 5.2 inches wide by 2.75 inches high. It weighs 4.5 pounds.
Fixture interior space, mounting arrangement, and wiring condition should be verified before installation. The compact assembly is intended for conversion work within existing metal halide fixture housings.
Where This Product Fits Best
This retrofit kit fits projects centered on converting existing metal halide fixtures to LED operation. It is suited to planned upgrades and maintenance work where the fixture housing remains in place.
- fixture retrofit projects
- legacy fixture conversion
- energy upgrade projects
- maintenance-driven lighting upgrades
- tenant improvement projects
- warehouse lighting retrofit
The available voltage configurations support systems operating from 100V-277V or 277V-480V. Existing fixture condition, internal space, and electrical configuration affect final retrofit fit.
Installation and Long-Term Use
Installation requires confirmation of the existing fixture condition, available internal space, and input voltage. The selected retrofit configuration must match either 100V-277V or 277V-480V service.
Optional dimming should only be considered where the project includes a compatible dimming approach. The supplied data does not establish mounting hardware compatibility or wiring requirements.
How This Fixture Is Commonly Used
In fixture retrofit projects and legacy fixture conversion work, the LED assembly is installed within an existing metal halide fixture rather than replacing the complete fixture. Mounting height should be evaluated with the existing fixture layout and target light levels.
For warehouse lighting retrofit and energy upgrade projects, fixture spacing and layout patterns are normally retained or adjusted based on the required light distribution. Higher output can reduce the number of active fixtures in a layout, but final placement depends on project light-level requirements.
Safety, Certifications, and Warranty
This retrofit kit is ETL listed. It is rebate eligible.
Warranty information is not included in the supplied product data.
