The Mankerlight MK37 is a small but powerful searchlight with an extremely high output. The flashlight is available for purchase with two different configurations: in fact we have a version with LUMINUS SBT90 GEN2 LEDs of Max. 5,800 lumens output, Max beam intensity of 218,556 cd and Max. 935 meters beam distance and a version with 1x OSRAM GREEN LEDs of Max. 3,000 lumens output, Max beam intensity of 525,625 cd and Max. 1,450 m beam distance. The light has a PMMA TIR lens for a high quality, homogeneous and artifact-free beam. In addition to this there is also a thick mineral glass lens with double anti-reflective treatment. The high efficiency constant current circuit guarantees an always stable output (No-PWM). The temperature regulation module effectively protects the light when it is used on high levels: in fact, it automatically decreases the output if the temperature of the light reaches critical levels. There is protection against polarity inversion which avoids damage if, for example, the user inserts the cell incorrectly, and there is also protection against excessive discharge of the cell. These two systems allow to extend the life of the flashlight and its components such as the LED circuit and the battery. The user interface provides six levels of constant light brightness and a stroboscopic flashing level. For the configuration with LED Luminus SBT90.2 the output levels are divided as follows: we have a moonlight level of 0.1 lumens and 70 hours of autonomy, a low level of 70 lumens and 30 hours of autonomy, a Mid1 level of 400 lumens with 9 hours 30 minutes of autonomy, Mid2 of 1100 lumens and 4 hours of autonomy, high of 2800 lumens and 1 hour 40 minutes of autonomy, turbo of 5800 lumens and 1 hour and 25 minutes of autonomy and finally the strobe of 5800 lumens. For the configuration with OSRAM Green LEDs, on the other hand, the levels are divided as follows: Moonlight with 0.1 lumens and 70 hours of autonomy, low of 60 lumens and 28 hours of autonomy, mid1 with 220 lumens and 9 hours of autonomy, mid2 with 550 lumens and 05 hours 55 minutes of autonomy, high with 1200 lumens and 02 hours 30 minutes of autonomy, turbo with 3000 lumens and 1 hour and 25 minutes of autonomy and finally the strobe with 3000 lumens. The Mankerlight MK37 is powered by 3x 18650 (not included in the package). The interface management switch is located near the head nestled between the deep and thick dissipation fins. inside the switch there is a LED status indicator that lights up in different colors to show the residual capacity of the cell: When the battery has a voltage greater than 10.8 volts per hour, the LED status indicator turns on will glow blue, if the battery has a voltage between 9.6 volts and 10.8 volts then the indicator will light purple, If the battery has a voltage between 8.7 volts and 9.6 volts then the light it will be constant red while if the cell has a voltage lower than 8.7 volts then the light will turn off automatically.
