I have not had a chance to review this Pico light yet, so I still carry the Photon. The problem with the Photon is that it can accidentally get turned on. The "demo" mode is not real useful, but you can easily set it to momentary on by pressing the switch a few times fast. It will then on turn on when it is pressed and turn off when released. If you hold the switch down for a few seconds it goes back to normal mode. I know this does totally alleviate the problem but it minimizes it.
