High Visibility Hardhat Headlamp. Designed with both job performance and worker safety in mind, the Princeton Tec EOS 360 is a hardhat headlamp that offers be-seen lighting in addition to traditional task lighting. A durable, rubberized band fitted with LEDs and reflective strips that encircle the hardhat creates high visibility of the user in industrial environments. Mounted on the front of the LED band is our EOS Headlamp for focused hands-free illumination. Both the LED band and the EOS Headlamp offer a variety of modes and function independently from each other.
