Kit includes * Edison Lamp * 13.8 Amp-Hr Lithium Ion Battery * Charger One battery charger * Helmet Mount * Car adapter * 120cm Extension Cord The ultimate lighting system for 24-hour solo racers or riders who relish epic night rides. The Edison has been ridden to victory by Chris Eatough, the undisputed king of 24 hour racing, Jenn O’Connor, Marg Fedyna and Mark Hendershot. So why is the Edison so much better than other HID lights? Our unique electronics allows us to provide 16W, as compared to the standard 10W. This increases the light output from the typical 500 lumens to a staggering 900 lumens, or the equivalent of a 65W halogen bulb. Light output on the high setting is noticeably brighter than "standard" 10W systems, and the 18° beam divergence angle is narrow enough to concentrate light effectively yet still offers excellent peripheral lighting even when bar mounted. The advanced ballast allows the Edison to switch to a lower 10W power level, as well as providing a battery warning and reserve tank feature. No matter if you ride all night long or commute to work a whole week, on 10W power level you don’t have to recharge. In spite of extreme runtimes and brightness the Edison still provides the world’s most compact design. This is only possible by using a modified version of the Welch Allyn bulb and ultra light weight Li-Ion batteries. ** Please email for frequent sale price ** Edison 10 models take about 2 weeks or less to arrive to you.
