The RING LED is the lighting solution for the precise examination of parts for a number of fields of application from mechanical engineering to research and development. This workhorse of a light is all business. The sleek design is minimal and fits easily into any workspace. The luminaire head is less that ½ thick and a mere 5 in diameter. The specially coated, distortion-free Eschenbach magnifier lens reaches 2.8 in diameter and offers 5.3 distortion-free diopters. Using six innovative LEDs provides critical added value compared to conventional fluorescents: four times more light per watt, considerably lowering energy consumption. These LEDs offer a minimum of 50,000 hours of operating life at 100% brightness level maintenance free for over six years running 24/7!
