The Point Hat Clip is an LED light designed to clip on the bill of caps in order to illuminate the immediate work area of the wearer. The Point Hat Clip, from Princeton Tec, is a task light with a flexible neck to direct light wherever it is needed. The white Ultrabright LED is recessed into a rugged aluminum head, providing directional light, to keep a low profile and eliminate the chance of blinding others. At just 17 grams the Point Hat Clip is virtually weightless. A press of the large, convenient button activates the light. This light is ideal for fishing or tinkering with tackle in low light conditions providing just the right amount of light to illuminate the work space as you tie on another lure or unhook fish. What's really neat about the hat light is how convenient it is - think about it, wherever way your head moves is the direction you need light. When you look down your light moves down, turn to the either side and your light follows - what a novel concept. The Princeton Tec Point Hat Clip light is a 10lumen led lamp that offers 36 hours of burn time from the two included lithium batteries.
