DL2GN Gooseneck Industrial Task Light

Part of the innovative DL2 Series, the DL2GN Gooseneck is designed to resist sag while providing unrivaled flexibility and light quality compared to traditional models.

The DL2GN Gooseneck features “set and forget” positioning, allowing operators to set the model to their optimal position and leave it without obstructing forklifts or the door. Its engineering resists sag by utilizing gravity as an ally. The flexible neck is mounted to the swing arm’s top, harnessing gravity’s pull to support the neck. Movement is transferred to a base hinge, significantly reducing friction caused by repetitive movement and repositioning. By using a stage one adjustable bar, Tri Lite reduced the size, length, and weight of the flexible neck, preventing sag over time. The model also includes a US-made high-impact polycarbonate head with optimized internal LED, further reducing weight compared to PAR38 lamps and metal heads.

The DL2GN Gooseneck provides optimal lighting for illuminating a 53′ trailer. Tri Lite uses the same light engine for the entire DL2 family, ensuring consistent high-quality features like CRI, color temperature, beam angle, and maximum-minimum ratios for all DL2 Series loading dock lights.

Partner the DL2GN with our DL2IL to create the best, most versatile form of illumination available on the market.
