After using just the Mule around the house last night, I'm giving serious consideration to buying some Cree strips, XR-E's, and Xitanium 700mA drivers. For most purposes, the Mule provides more than sufficient light for even my 12'x30' bedroom, so I'm sure that it wouldn't take very long to recoup the cost and then start saving money.
I think calling the Mule a flashlight is really a misnomer. It's really just a light that happens to be shaped like a flashlight - but a very useful one. I have no idea how many times I've got in search of some small lost item, either outside or in the car at night. A flashlight does okay for this, but the wide flood of the Mule will be far more practical for such searches. And it will be superb to have around during the rare power outages we have.
I suspect a lot of folks will miss the point of the Mule, but for those of us that have one, well, that'll leave more of them for us! :naughty:
