    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    Fits easily SKU.39191, which is Ultrafire C3 with DX logo on it.

    Cons:

    None, except for the price. It could really be cheaper, considering it is a machined piece of aluminum with no electronics.

    OtherThoughts:

    Basic C3 with either P4 or Q4 LED is slightly brighter with 2xAA's than with 1xAA, but with 14500 it is almost twice as bright as with 2xAA. On the other side, SKU.39191 with Q5 installed instead of Q4 is as bright with 1xAA as Q4 with 2xAA and with 14500 is again about two times brighter and almost equal to Q4 version.

    Bottomline:

    A good choice if you need longer runtime over light output.
