100 Watt Metal Halide LED Retrofit | 15500 Lumens | 400 Watt Replacement | 4000K or 5000K | 100-277V

Product Overview

This 100 watt LED retrofit is designed to replace 400 watt metal halide fixtures. It produces 15,500 lumens at 155 lumens per watt, delivering equivalent light output at a fraction of the original wattage draw.

The retrofit is available in 4000K or 5000K color temperatures and operates on 100-277V input. It measures 6.1 inches long by 5.2 inches wide by 2.75 inches high and weighs 4.5 pounds. Dimming is available as an optional feature.

Where This Product Fits Best

This retrofit fits applications currently using 400 watt metal halide fixtures where the existing housing and mounting infrastructure will remain in place. The 100-277V input range covers standard commercial and industrial voltage configurations.

The 120-degree beam angle provides broad light distribution suited to general area lighting. With a CRI of 75+, this retrofit works well in warehouses, manufacturing floors, and storage areas where color accuracy is functional rather than critical.

Performance and Functional Considerations

At 15,500 lumens from 100 watts, this retrofit operates at 155 lumens per watt. The power factor exceeds 0.90 and total harmonic distortion stays below 15%, supporting clean electrical performance on commercial circuits.

The LED components carry a rated lifespan of 100,000 hours at L70, meaning the output will maintain at least 70% of initial lumens at that point. The driver is rated separately at 50,000 hours. The unit operates on 50/60 Hz frequency input.

Installation and Long-Term Use

This retrofit installs into existing metal halide fixture housings. The compact dimensions and 4.5-pound weight keep it compatible with standard mounting configurations. Voltage compatibility across 100-277V eliminates the need for transformer matching in most commercial and industrial panels.

Long-term maintenance centers on the driver, which has a shorter rated life than the LED array. Optional dimming capability allows integration with compatible control systems where site conditions support it.

How This Fixture Is Commonly Used

Facilities replacing aging metal halide systems use this retrofit to maintain existing fixture positions and wiring while reducing energy consumption. The 4000K option provides a neutral white appearance, while the 5000K option delivers a cooler, more daylight-like output. Color temperature selection typically depends on the visual environment and any existing lighting in the space.

Where dimming is specified, the retrofit can be adjusted to reduce output during low-activity periods or to balance light levels across zones. The 120-degree beam angle spreads light broadly, which works well in open areas without requiring precise aiming.
