Review on Cobiz Brightest High 6000 Lumen CREE LED Headlamp - Rechargeable, Waterproof, Zoomable Light – Perfect for Camping, Hiking & Outdoors by Mario Hinton

Pretty and bright doesn't seem to carry much weight if I warn. Cons: The two included 18650 batteries tested lower than advertised (2200mAh), one tested at 1429mAh, the other at 1531mAh. that have a shorter term. This is an unbranded battery, most likely a cheap fake you can find on ebay. I would suggest replacing two 18650s with branded or established ones. suggesting that they are indeed similar to the Samsung 25R 18650 2500MAH 20A - BUTTON TOP BATTERY. available at 18650batterystore.com
