The Newage® 5620 Series HiLight Brinell Optical Scopes features a high-efficiency LED array for its light source, providing excellent illumination and improved readability over conventional “flash light” scopes.  The LED array consists of four individual LEDs positioned to provide an even and consistent definition of the Brinell impression’s edge. The 5620 Series uses a 3V lithium CR2 battery.  Up to 200 hours of continuous use is typical before a battery change is required.  An optional motion sensor/timer can be used to automatically turn the scope On/Off.
