Anything that is smaller, brighter, lasts longer, and cheaper than this. . It has to have all four of those characteristics. If it is bigger, but brighter, I won't take it. If it is brighter but more expensive, forget it. All right, I will give you some room. If it is 10X smaller, 10X brighter, lasts 10X longer and is twice as much, then I would buy it. But, I am not spending more than $20 on a headlight when this things works great for me.
