I would like to tell you that I have had this lens for a year and it is good that the battery lasts, but it depends on how you hold it and how you use it. However, it has served me well for a year and the lens is also powerful. It requires a little attention and caution for cycling or skating, but it is worth it for other purposes that the lens serves. If I have helped you a lot, you're welcome

I had the previous model with 200 candles. After a fall, a cable came off the head and it broke. It was good for its price. This model that I got now has more power and it creates an annoying green hue around the beam. It doesn't hold for long on the high setting. It works for me as a flashlight, but I have only tested it minimally so far
