The 6550CR from Vision X takes the intense HID technologies Vision X is known around the globe for, and takes it to the next level by going from the standard 35 Watt HID to all new 50 Watt HID Technologies that are better than ever, and all the components are still internal. The 6550 also comes in a composite housing versus the normal die-cast aluminum, still allowing it to be durable and rugged, but letting it weigh less than a traditional light. The 6550CR weighs in at just 3.75 pounds, almost half the weight of an HID-8500!
