The Maglite 2-AA with an incandescent bulb was a popular flashlight for many years. During the past several years, low cost white LEDs and LED driver chips have become available so I decided to convert them to white LED bulbs using a LED driver chip. Using a driver chip offers the benefit of a constant current drive and constant light output independent of the battery voltage. An additional benefit is that LEDs are a much more efficient light source and the battery life will be significantly longer for about the same light output.
