The JEDMED mobiLED+ handheld light source provides superior LED illumination for endoscopes and flexible scope applications. Patent pending optics collect more light from the LED for a highly efficient light source. The JEDMED mobiLED+ replaces fiber-optic light-guide cables or wires common to traditional light sources of the past. Enhanced mobility, ease-of-use, brightness and quality of light are achieved with this device. It uses a powerful, best-in-class LED, cooled by a comfortable, finned handle. An easy-to-grip intensity knob provides precise adjustments of light output and a quick-change battery. Internal circuitry protects against accidental reverse polarity should the battery be inserted in the wrong orientation, and maintains constant current to the LED as the battery voltage drops with use, for more consistent light output. A long life LED eliminates lamp replacement and requires no fan, providing a silent and energy efficient light source that is lightweight, compact and portable.
