    Pros:
    Bought as replacement of a foulty cree on a diving flashlight (112889) and works like a charm. probably brighter than the original but with same size. soldering was quite easy

    maybe it is a standard but + and - sighs dont match with red-blue on the flashlight.. probably it is a flashlight problem..?

    Pros:
    Nice Q5 emitter that has good build quality and easy to solder to its place. Fits for many purposes and easy to replace for an existing flashlight. Cheap and timesaving solution. Bought multiple of these for my projects.
    Cons:
    Nothing construction to say does its job. Well done.

    Pros:
    Great super bright LED! The heatsink section is sufficient for my use; I run at about 350 mA at 5V and it just feels a little warm to touch.
    Cons:
    The price could be a little cheaper then I would consider this an awesome Cree LED

    Heatsink requirements

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

    Pros:
    The aluminum star-mount by itself dissipates enough heat to allow continuous operation at about .75 watts and still maintain the junction temperature below 70 deg. C.
    Cons:
