The NITECORE MT06MD is an upgrade to the popular Mt06 with several new features to set it apart from the crowd. NITECORE swapped out the cool white LED of the Mt06 with a Nichia 219B emitter for a warmer beam at a lower Peak intensity (860Cd). the end result is a flashlight perfectly suited for up close tasks where details and colors are key factors. The MT06MD now also turns on by Default in a 4 Lumen low mode to prevent accidentally flashing patients with bright light or disturbing night vision. Offering up to 180 lumens max output, the MT06MD has three brightness settings which can be accessed with one hand via the reverse-click tail switch. Doctors, nurses and emts will find the MT06MD ideal for pupil examination and injury diagnosis thanks to the diffused beam and high cri rating (> 90) of the Nichia 219B. Not only will this penlight reveal color more accurately, but the output has an Rg0 rating to eliminate blue-light hazards. The MT06MD isn't only for medical professionals, either. Operating on 2 easily sourced AAA batteries and offering a runtime of up to 35 hours, the MT06MD works great for household chores - especially work in close quarters where a flood of light is essential.
