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

    Pros:

    Single chip so you need only one lens
    Compact so it can replace XR-E
    Massive white light output (4 times XR-E)
    Comes on individual wired star that is thick so seems to be a good heatsink 
    Has very low Vf

    Cons:

    Stated and partially made parallel - some of the pins came soldered together 
    Only bin currently available

    OtherThoughts:

    It would be much better to let the user decide die configuration so make it individual. 
    Much easier to solder pins together than to decouple them using desoldering wick
    didn't try to direct drive it to 18650
    temporarily mounted to a big heatsink
    UI characteristic (one die)
      If (A)   Vf (V)

      0.6       3.32
      0.7       3.35
      0.8       3.41

    Bottomline:

    Great for own DIY projects or flashlight upgrade
