Wow...Get the multimode version or you will regret it. I have several streamlights and they are quality equipment. With this bulb you can have three levels of light from one light. Max is 3 times brighter than stock, mid is about equal to stock but lasts 6 hrs, low is perfect for map reading in a car! It offers more flexibility than ever with a white light that is super white and bright!
Pros: intensity, battery life, light color, durability, economy
Cons: none discovered yet
