The latest Mini Mag-lite® AA-cell flashlights come with an LED bulb (the MAG-LED™ Technology, to be specific). If you have an older model Mini Mag-lite® and want to upgrade it, the Nite Ize® upgrade kit is a good option. For around $16, you get a 1-Watt LED bulb and an end-cap “IQ Switch®” that provides three power levels (100, 50, and 25 percent), two emergency strobe levels (fast and slow), plus an integral “find-in-the-dark” small LED that flashes every few seconds.
Flashlights: can you ever have enough? Bonus question: is being obsessive about changing all the batteries in your flashlights a flashlight feeding frenzy fetish?
