I havehad the lamp for a couple of years now. For over a hundred foxes it is the last thing they have seen. I only have to charge the battery once every 3 months.. It works best for me clipped under the barrel as it is so light that it is not effected by the recoil and does not effect the point of impact of the bullet. I would recommend taping the connections together at night as they pull apart too easily. I WOULD NEVER GO BACK TO LEAD ACID/ FILAMENT BULBS. IT WOULD BE LIKE GOING BACK TO USING BLANKETS INSTEAD OF DUVETS.
