I have one of these (still a flashlight). I got it as a gift.
I can see some limited value to the dimming and maybe the lockout (for safety) although I prefer a physical lockup to an electronic lockout.
However, the rest of the "modes" would seem pretty useless for a laser.
Nightlight mode looks downright dangerous for a powerful laser.
Also, it looks like the stock LED is only pulling about 430mA. That switch may indeed cause problems when trying to drive a 445nm at higher currents
You have to hold the switch for it to dim.
Also, for the other modes to kick in, you have to hold the button for a full second
Peace,
