It was a horrible experience to buy that lamp, it seemed to be so robust and of quality that I did not hesitate to buy it, but after 4 hours of camping it was extinguished without remedy, I was checking next to the bonfire I returned to the car and there was no way to resuscitate it. After visiting a technician he found that the plate that goes in the battery pack had burned and there is no way to repair it. This product is a total disappointment.
