Fortunately, you don't need to spend a lot of money to get a bright light, but to a point you do get what you pay for. The cheaper brands may burn just as bright but not for as long, and may not be as reliable. Choose wisely.
I would say some of the brightest light are also the cheapest, and there is no reason they won't last. I have an XM=L2 light that will outshine anything I've seen. It cost $20, although it didn't come with a mount but I already have one. I also put a high output battery in it and I have yet to run it down but I'm not using it for cycling.
Actually it was $14. The specific one is no longer on Amazon, but there are others just like it.
