5300 lumens, this is a theoretical value or 10 cm from the lamp. To be all on the same level, it should be mandatory to speak in lumens So standard that allows for an average lighting calculation on a given surface, not on a single point. However, I can tell you that ca rips everything. I already Magicshine flagship ATV on the ATV actually measured more than 900 lumens, and the lamp is more powerful. Deer were surprised at night, it was pretty funny. The maximum power in range around 50 m and beyond shows that ca lights anyway. In short, it's a really good lamp. I still opted for a 8800 mah battery autonomy, keeping that provided rescue. It would be a shame to stay in complete darkness. Thanks to the latter, juggling between the two powers, I held more than 2:30!
