Our headlight cables are designed to deliver the maximum light output and performance when used with our Sunoptics Surgical headlights. The patented process of fusing the fiber bundle at the proximal end combined with using a high quality lens to focus the light results in an increase in light transmission outperforming the competition. This along with Sunoptics Surgical Moulded UltraGrip handle provides added strain-relief, plus durability and ease of cable removal from the lightsource.
