Allows user to increase or decrease light output of any Mike Lite.
Optimizes available battery life by allowing user to decrease the Mike Lite output with fresh batteries. As battery life decreases, user slowly increases output to maintain favorite light setting. Also convenient to adjust the light output to compensate for various ambient light conditions as well as different levels of dark adaptation.
