GearBest offers the Skilhunt H03 LED Headlamp in Neutral White for $41.05. Coupon code "L2U4S" cuts it to $31.99. With free shipping, that's the lowest total price we could find by $18, although we saw it for $2 less last December. It features a maximum light output of 1,000 ANSI lumens and can be used as a flashlight.
Note: It ships from mainland China and may take three to six weeks to arrive.
