For whatever it's worth, I think I've spent more money on cheap bad lights than on good lights. I hope this lesson is useful for some. I've seen some good reviews for cheap lights, but clearly, some are easier to please than others. Lights designed to mount on bicycles prove to be more trouble free for me. I tried using a powerful flashlight and a handlebar flashlight mount. Yeah, it was super bright, but the beam was awful. And I had to take the light off, disassemble, and remove the cell to charge it. I like things to require as little labor as possible. That's why dynamo lights are best for me most of the time.

Here is my article on my current dynamo system which I've been using for over two years. The cost to me was about $160 for dynamo hub and both lights, and I haven't had to plug it in or think about it for all this time.
