I've used other brands and other models of this brand headlamp and this is the best one I've purchased so far. Love the intensity levels and having red or green options of lighting your way. I use it for hunting and out photographing at night. It's bright enough to follow a blood trail during the archery hunting season, and it's delicate enough to not wipeout your night vision while trying to see the buttons on your camera for night photography. I'm very happy with the ability to recharge the battery and how long the charge will last more than meets my requirements. The LEDLENSER model I replaced this one with required 3 AA batteries and it went through batteries like crazy. I also purchased the power case from LEDLENSER which is perfect for backpacking and you need a charge before you get back to an outlet. Highly recommended!!
