Working in a dark, tight space? Need an extra hand to shed light on the situation? Today you'll learn how a little clip-on LED light is both a solution and ?bright? idea! The mini clip-on Bil-Lite may look unimposing, but in reality it's a virtual powerhouse, with a state-of-the-art LED bulb that shoots a brilliant shaft of light through an optical-grade lens, creating a hard-edged ?crisp? circle of light as far away as 30 feet. Unlike conventional AA- or AAA- powered penlights that are heavy and run down quickly, Bil-Lite's two lithium battery disks last for 100 hours or more, and the whole shebang, batteries and all, weighs just one ounce. Also, the bulb lasts for 100,000 hours. Bil-Lite clips onto your hat's bill (thus the name), or to pockets, belts, or anywhere else. It swivels 360 degrees and tilts 90 degrees to put light right where you need it, all for about $20. Then you, too, can say ?Beam me up, Scotty!?
