Overpriced, but excellent replacement - Lightstar MiniStar5 LED Upgrade for Maglite (C&D Cell)

I can't testify to how long it lasted since I haven't had it that long, but it is much brighter than the standard bulb, has an awesome white light and in theory should last much longer than a regular bulb. Course they know that so they charge much more than a regular bulb.
Pros: Bright white, long lasting
Cons: Price
