LED Calculator 2.12

LED Pro was created to help you make informed and educated flashlight modding decisions, and to calculate aspects of your design, by entering certain known variables.
To use LED Pro, you merely enter all but one of the variables and let the program calculate the unknown one.
At this stage, the usage and results are very simple, and as time progresses the LED Pro Team will release updates that allow you to complete more complicated functions, and do so with greater ease.
