The Model 8770 GEN3 is a high-performance, 7-inch round LED headlamp engineered specifically for locomotive applications. It serves as a powerful, FRA-approved replacement for traditional PAR56 locomotive headlights, delivering exceptional illumination and reliability in demanding rail environments. Designed for rail systems that use only high and low beam functionality—controlled via a designated control line—the Model 8770 is also well-suited for 75V ditch light applications, making it a versatile solution for a range of industrial rail lighting needs.
Offering a powerful minimum candela output of 230,000, the Model 8770 ensures long-distance visibility and optimal safety on the tracks. It features SmartHeat® technology, which automatically activates to melt snow and ice off the lens surface, preventing obstruction and ensuring consistent performance in extreme weather conditions. The headlamp’s die-cast aluminum housing provides maximum durability and protection against the harsh operating conditions common in railroad environments, while its rugged polycarbonate lens remains clear and resilient over time.
Constructed with heavy-duty materials and solid-state electronics, this headlamp delivers long-lasting performance and requires significantly less maintenance compared to halogen alternatives. With an effective lumen output of 1,800 lumens (from a raw output of 2,200 lumens), the Model 8770 provides focused, high-intensity forward lighting with a tight spot beam and a nominal color temperature of 5100K for bright, white daylight-like illumination.
The Model 8770 operates within a wide input voltage range of 24–110V DC and is compatible with sealed beam style screw terminals for simplified installation. It is designed to retrofit directly into standard 2D1 PAR56 or 7-inch round locomotive headlight housings using a panel mount configuration. The fixture withstands operating temperatures from -40 °C to 65 °C (-40 °F to 149 °F), making it reliable in a broad range of climates.
Ideal for both industrial and railroad applications, the J.W. Speaker Model 8770 GEN3 offers a cutting-edge upgrade to traditional locomotive lighting with unmatched durability, advanced thermal management, and compliance with all Federal Railroad Administration (FRA) requirements.
