My 1st light I built was a simple click on/off switch, 2 123s, and a Cree drop-in. Now for my 2nd I have been reading up on 3 mode drivers and it seems to me that the driver most of the time contols the 3 modes not the switch. I first thought the switch controlled this, correct me if I am wrong. Now my question is will a single mode click switch work with a 3 mode driver or is there a 3 mode switch and if so which do you recommend.
