I was working on a freinds computer swapping out the hard drives & dropped my light on the table. It was about an 8 inch drop if that. I picked up the light to see what I was working on & it was flickering real bad. I unscrewed the back & took out the battery cage. Sure enough the batteries were ajar. Snapped them back in place & all was fine. My point is, if this had been an emergency situation would you ever trust this setup again? Not me! No more lights with battery cages for me. Thanks for reading my rant.
