This company makes great headlamp and other lighting prroducts
I got my Wuben H4 from a friend and I really like it. It's a headlamp with built in battery but also capable of using 3xAAA batteries. I was surprised that it has motion sensing control, the feature where user can control the headlamp just by waving our hand over it. Later I checked their website to learn more about this headlamp. I found that Wuben makes flashlights, headlamp, and other lighting accessories. I'm currently saving some fund to purchase their G5 series (the yellow one looks dope).
