Review on Flashlight Replacement Maglite Conversion Flashlights by Willie Midkiff

Excellent product for overall brightness and extended battery life. There is an anomaly where the beam focus point appears as a dark spot when you try to use it in an application that has a beam focus mechanism like a Maglight or Ryobi flash. If they are critical to your application, this may not be for you. They're inexpensive enough to try, so I'd recommend experimenting to see how they work with your flashlight. For me I need a long light and a bright light. This lamp worked great. If you're in the middle of a hurricane and there's no power, this lightbulb is a lifesaver by extending battery life to several hours. The perfect solution to my problem. Now I have 4 flashlights with LED bulbs.
