Just got my drop in. This makes the Mini into the light it should have been. The drop in is brighter than my old P2D EDC I've been carrying for years. Coun't me in on the next run. What about upping the driver amperage a little more like you said on an earlier post.
I see the 1v-3v rating, but any idea what a 4.2v from a 14500 would do to the circuit.
