I've been really impressed with Coast brand flashlights and headlamps. All their lights come with a lifetime warranty. They're not well known so I thought I'd put in a plug for them.

Their smaller lights aren't set up for rechargable usb though. Their cheapest light that's rechargable has three settings from 530 lumens to 65 lumens and it's $105. The 4 setting 400 lumen headlight I am curently using came in a $28 two pack at Costco and takes 3 AAA bateries.
