For those of us with incandesent bulb Mag-Lite flashlights I came across these drop-in Rayovac LED replacement bulbs at Walmart the other day.

Nice upgrade over the standard Xenon bulbs. Bright white light with a hint of blue and a sharp focus circle. Should offer a big improvement battery life as well. Not bad for $3.88
Note: The 2 cell, 30 Lumen bulbs perform better in 3 cell flashlights iver the 40 Lumen, in my experience at least.
