Is there such a driver readily available that will fit inside the head of a p60 type flashlight?
the host i plan to use has approx. 17mm diameter usable space and can accomodate about the same in depth give or take depending on the sizing of heat sink that will be a custom fit.
This is a single 18650 configuration. I can go the double cr123 route for a higher input voltage but already have plenty of 18650 so prefer to stay with that power source.
Looking for 5 to 6 amp regulated or direct drive on high with three output modes High med low. High is no more than 30 second burst the medium and low will be used fairly constant so prefer those to be regulated.
Any suggestions appreciated
