A:AnswerThere's a diagram on the outside of the cap to the battery compartment, indicating the batteries are all inserted with the positive terminals down, facing towards the light end of the flashlight.
A:AnswerHow did you decide it only puts out 900 lumen? I have a 900 lumen LED flashlight - different manufacturer - and this 1300 lumen LED flashlight. (I need bright flashlights for my work.) This 1300 lumen flashlight is clearly brighter than the 900 lumen flashlight, especially when I'm inside a totally darkened structure. I am happy with both of my lights. Not so much for the 350 lumen one I bought previously for the same reason. It works well and is well-made - it's just not bright enough. These two (900 and 1300) are awesome.
A:AnswerYes. There is a lot of heat generated by the LEDs and the heavy metal case radiates this heat away from them to keep them healthy. Unless you need the full output I suggest holding the on switch down to toggle through the dimming and focus ranges - this keeps heat down and also extends battery life dramatically.
