With the buck/boost converter KI-B can run primary 1 x CR123A, 2 x CR123A, alkaline AA size or AA size Ni-MH batteries. For the Li-ion fans the light will run protected 1x RCR123A, 2 x RCR123A and 14500 batteries. The KI-B has brightness, longer run time and multiple battery choices.
To keep the light simple only one new converter is necessary for the light. The light will be using a buck/boost converter to power the different battery voltages. The new converter has an input voltage range from 1.2 volts to 9 volts allowing many power source options. To extend the run time, generate less wasteful heat and insures long life of the emitter, the converter output is running approx 375mA of current. That is good for extended run time but what about the brightness? To make up for less power to the emitter a more efficient emitter will be installed. The emitter will be using a Lux I, S-bin, emitter. That's right, a bright S-bin Lux I emitter! Early results indicate the Lux I could have an output of 51.7 to 67.2 lumens. The converter/emitter design is pared together to get the most efficient use of battery power and a bright beam
