Which part of the meaty part of the market doesn't use external batteries?

This is nice as well.

I would never buy a clone from fastech, the batteries are an accident waiting to happen.
These were in the running as well, great lights, german designed.

Magic shines and such, naw, I wish to have a battery that I can trust won't blow up and light on fire when I charge it.

The Fenix I bought is a chinese light, it's just a step up the rung, doesn't try to be something it isn't. It's properly rated and actually waterproof. The batteries are not dangerous if you don't cheap out on them.

I need not bring a four pack of lithium ion batteries into my house that are charged with the cheapest non balanced method known to mankind in order to have a light that is rated at twice it's real lumens.

If that is the meaty part of the market i wish to be a vegetarian. All the rest can eat meat, it is of little consequence to me.
