You need to use ONLY the amount of light you need to perform a specific task!!
If you work your headlamp this way, then this headlamp will work for you. NO headlamp blasts 600 lumens for a 10hr day. This one has 4 modes. Its durable, recharges quicker than ANY other, and holds its charge for weeks. Also, you can charge it ANY time you want, even if its not dead, without harming the red lithium battery. What else could you ask from a headlamp. I have 2 fully charged, and swap during the day, if im really working dark. I've only had to change out twice, because i was running on high output for a long amount of time. Don't let anyone say this headlamp is bad, because id have to say their headlamp is bad...lol
