Hi guys. I've gotten a Photon Freedom from RF some time ago, but for the life of me, couldn't get it into "strobe" mode. I thought I could live with it since the thing is my back-up anyway, but it's just driving me nuts. How do I do it? I press the button down as instructed, but after the light "blinks" at full power, nothing happens. Absolutely nothing. It just keeps shining. What am I missing?
