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

    Pros:

    Very bright LED

    Drill-Holes fit old Pentiom CPU-Cooler with 40mm fan

    Works wirth many laptop power-supplies (e.g. 19V, 3A), only simple Current Source needs to be added (1 N-Channel Power MOSFET, 1 NPN Transistor, 2 Resistors)

    Cons:

    The given Current-Rating too high. Only use the LED with 1750mA max.!

    Light-Output seems too optimistic. The Datasheet says 2300 lumens max. (@1.75A)

    OtherThoughts:

    i will try this LED as a light-source for an old DLP-Beamer. 2000 lumens would be nice to get.

    Bottomline:

    get the datasheet here:
