Review on Q5 LED Tactical Flashlight, Pocketman 6 Pack, 7W 300LM SK-68 Mini Light Black With 3 Modes by Bob Ramthun

Flashlights with one battery are best. My theory is that battery connections in a flashlight will drop the voltage low enough that it will not illuminate. I can rap it on something to get it working, but that sometimes fails, and then I put it down, turned on, but looking like it is off and the batteries slowly go dead. Flashlights with only one battery fail to illuminate less often.I like that these flashlights can be off, on bright, on dim or flickering. The zoom lens is nice, too.I have bought rechargeable, slow discharge batteries for these flashlights, so I can leave them installed, and ready for use, with no worry about killing them with dead battery juice.
