115 Watt LED Street Light Retrofit Lamp | 14950 Lumens | 5000K | 400 Watt Replacement

Product Overview

This 115 watt LED street light retrofit lamp delivers 14950 lumens at 5000K, designed as a direct replacement for 400 watt metal halide lamps in existing street light fixtures. The lamp operates on 100V-277V input, making it compatible with most roadway and area lighting electrical systems.

At 130 lumens per watt, this retrofit lamp converts existing street light housings to LED operation without replacing the entire fixture assembly. The 90 x 150 degree beam angle produces an asymmetric light pattern suited to roadway and pathway applications where throw distance and lateral spread matter more than symmetric distribution.

Where This Product Fits Best

This retrofit lamp fits street light fixtures currently running 400 watt metal halide lamps. The mogul base design allows installation into standard street light sockets without fixture modification. The 11.7 x 5.4 x 3.4 inch dimensions and 3 pound weight should be verified against the existing fixture housing to confirm clearance.

The 100V-277V operating range covers standard utility voltages found in municipal and commercial street lighting circuits. The 50/60 Hz frequency compatibility supports installations across different electrical infrastructure standards.

Performance and Functional Considerations

The 14950 lumen output at 5000K provides a daylight color appearance typical of modern roadway lighting. CRI of 80+ supports adequate color rendering for general outdoor visibility without the color shift common in aging metal halide lamps.

The asymmetric 90 x 150 degree beam angle throws light forward and to the sides rather than directly downward. This pattern is engineered for street light applications where illuminating the roadway ahead of the pole matters more than illuminating the area directly beneath it. Power factor of .9 indicates efficient use of supplied current with minimal reactive load on the electrical system.

Installation and Long-Term Use

Installation involves removing the existing metal halide lamp and ballast, then wiring the LED retrofit lamp directly to line voltage. The lamp is designed for ballast bypass operation. Verify that the existing fixture enclosure can accommodate the 11.7 x 5.4 x 3.4 inch lamp dimensions before ordering.

Rated lifespan is 50,000 hours. At typical dusk-to-dawn operation of approximately 4,000 hours per year, this translates to roughly 12 years of service before output drops below rated levels. The 3 pound weight is comparable to standard HID lamps and should not stress existing socket or fixture mounting hardware.

How This Fixture Is Commonly Used

Once installed, this retrofit lamp operates as a direct-wire LED source with no user-adjustable settings. The 5000K color temperature and 14950 lumen output are fixed at the values listed. Day-to-day operation relies entirely on the existing photocell or control system wired to the street light circuit.

Maintenance consists of visual inspection and eventual lamp replacement when output degrades. The retrofit approach preserves the existing street light housing, arm, and pole infrastructure while converting the light source to LED. This matters in applications where fixture aesthetics, historic preservation requirements, or existing infrastructure constraints rule out full fixture replacement.

Safety, Certifications, and Warranty

This lamp is UL listed and rebate eligible. The 5 year warranty covers defects in materials and workmanship under normal operating conditions.
