I have related the LED hand lamp for my company through Amazon. Perfect service by the way! Had ordered Monday by 16 clock and on folgenen Tuesday at 11 clock at the front door. For lamp: I use them, as already mentioned in my company. I can without any problems an entire working day in use have (8-9 hours - 5-6 hours of it on), 5.5 hours, it is already running at a time and the battery has not been limp. Even after 4 months (use almost every day) no worse or fluctuating power. The luminosity is neat and the air is well finished, it has already been dropped me a few times and nothing happened. The hanging hook and magnet are quite practical, the charging station needs an average of 3 - to charge the battery fully again four hours and the work lamp is very good in the hand. I am completely satisfied!
