With a range of 13 NM to 22 NM at 0.74 T, the VLL-43 Linear Lead Light is a powerful unidirectional light ideal for marking short distances and obstacles. Its optical system utilizes an acrylic lens to effectively capture and project light from high-powered LEDs. These LEDs are carefully graded and positioned to create a beam with minimal variation in intensity. Multiple units can be deployed to achieve the desired range, with each unit featuring its own control board for individual operation.
