I have two more flashlights from the same consignor ordered (some time ago). Therefore, I was shocked at the beginning of the low light output, then went to a few seconds nothing. It has proven to be fast, these were the enclosed AA batteries already empty. 2 new reingetan, and now the wow effect came. From only 2 AA batteries, the light output is impressive and useful in the dimmed mode for longer missions. I find the article also so convenient because there is no unnnötigen extras. 2 light, finished. More does not need. Unbeatable for the price. I admit, despite the empty batteries 5 star, since the cost of the batteries are so cheap anyway.
