I tried with the D-mini as it is, dont think you can drop in a P60 module led?
I have one of the first dminis, didnt know there where any other...
One thing i did notice is that the tailcap makes a buzzing sound when ramping the light up. And I think that the output where a bit less than with the original tailcap, but im not sure. The TLS tailcap screws down to the last of the two o-rings on the dmini, but It looks kinda cool!
