for the money i feel this is a nice upgrade if you have the original stinger led with the C4 bulb. I personally feel this is not 2-3 times brighter, but you can def tell a difference. the focus beam of light is much cleaner and tighter.
Pros: Easy to install, brighter, fast shipping
Cons: not 2-3 times brighter
