ThorFire CREE - Headband_Headlight
CREE makes some really bright LED's. This ThorFire CREE headlamp assembly is something like 5000 Lumens, on it's BRIGHT setting. I ordered it for around $15. I salvage lithium batteries from old laptop battery packs, and this headlight operates off of just one cell. A single lithium cell from a laptop pack is 3.7 to 4.2 vdc. I solder two cells in parallel, and solder the wire from the headlight to the homemade battery pack. I recharge with a lithium charger I use in my RC hobbies. In the link provided, you can opt to purchase the charger/battery from them if you don't want to tinker. Here's where you can get the headlamp, within the description you will see links to the charger and battery pack. Once you go to the link below, search for this item number: SKU131517
