This is an LED headlamp ( very bright white light ). It has 4 settings, spot, flood, spot & flood and strobe.
Now you can buy these on Amazon for about $10 but the AA battery ( pic 2 ) last about 25 minutes on a charge. I professionally modify these with a pair of 3000 mAh lithium ion 18650 weld tabs to solder wire, they cost $8 a piece. You will see in the pictures. This headlamp will last 10 hours at least on a charge at full intensity, longer on any other setting. The pair of cells you see in pictures 3,4,5 tested at 5994 mAh. I know this is a long shot but for the construction worker that wanted to buy my light a couple of months ago here you are, no more changing expensive "AA" batteries 3 times a day. If you use it every day these should last over 3 years then slowly weaken. You will be the envie of all your co-construction friends.
