This lamp is wonderful in the hand and people burning with two normal batteries. This eliminates the financial Expenditure for the purchase of a battery charger and then after all 4Accus (two in the air and two for replacement) 274Lumen performance that's pretty bright. Have one with 380Lumen from another manufacturer, but is shorter and has a smaller diameter, which is not bright. And one from the Asian region with supposedly 1600Lumen which is rather darker. The burning time I find with 8 hours is sufficient, but I would after a certain period of use, or always take when planning a longer operating time, two spare batteries. Because dieLampe goes with used batteries LED.typisch quickly. From me there is a strong buy recommendation, since robust, valuable, bright and MAG-LITE quality
