See video on Amazon.com Several major advantages for this headlamp, compared to other models: * Charging with USB Cable for not having to change batteries * Battery life and diodes * Ability to have multiple lighting modes (see video: main diode, or red side nocture) * Ability to adjust the intensity leisure * Accessibility of control buttons (one button does it all, and is very accessible) * Simple adjustment straps, fits very well to all heads * Light, is doing very well for long hours * Sealing and allows me to use in all conditions, including rain / snow.
One disadvantage if you do not have a portable charger: the battery does not change, and so you need to remember to be recharged in advance (the autonomy is very good, a few days, but it depends and your use of the chosen intensity). In my case, I have a standalone charger, there are in all price and very small, it is also very practical! I personally love this model: RAVPower Luster with 3200 mAh external battery and flashlight Charger UV LED (iSmart, dog and cat task detector, counterfeit detector, 1000 recharge cycles)
