i bought a 2 pack of lights at sams club yesterday. rocky brand. one light is a 220 lumen and the other is a 160 lumen. $25. i figured it wasn't a bad deal. i've been looking for a new daily carry light. within the first 5 minutes i was ready to take them back. it's a multi function switch. push the button once and it turns the light on at 50% power. push it again and it turns on 100%, push it a third time and it goes into a strobe. push it a 4th time to turn it off. you have to push the button 4 times to turn it off and on. i hate that. i destroyed the package taking them out. i may have to pay a re-stocking fee but i think they're going back this afternoon.
