    Pros:
    I bought this to replace the Nichia LED array in a popular 3xD camping lantern so it had a better tint and added brightness. The tint is pretty good (close enough to WG) although it varies toward the edge and centre
    Cons:
    It was a bit tricky to solder the connections to make all 4 dies work in parallel because of the gap between the pins. I had to...

    Pros:
    pretty bright I made a household bathroom bulb with this and it works well inside a white batroom diffuser. Drove it at 1A Vfw is 3.9V glue to a cpu heatsink. I just use old transformer with resistor in series to drive it.
    Cons:
    no cons other than it gets pretty warm. I'm using an old pentium M cpu heatsink to release the heat. It seems warm to the touch.

    2nd batch not as good as 1st

    posted by techjunkie on 12/01/2008 Certified Owner

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

    Pros:
    Bright and powerful. Pretty straightforward replacement for CREE XR-E, with small challenges to focusing and power supply.
    Cons:
    2nd set of boards I received were serial, not parallel. Had to scratch trace routes on board and solder together leads on each...

    Genuine product. Not parallel board.

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

    Pros:
    Nice product. Mounted well to serial board although advirtised as parallel. Beautiful unit, if wired correctly it should shadow the P7.
    Cons:
    Wrong format for me. Had to manipulate many things to accomodate this item. This is quite an inconvenience considering the time...

    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

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

    Pros:
    Super bright, great white tint, much easier to focus then P7.

    Very pleased

    posted by techjunkie on 11/05/2008 Certified Owner

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

    Pros:
    Very white, very bright, very nice upgrade from single die emitter, especially CREE. Easy to swap a 20mm CREE XR-E star with this MC-E star (if you can solder). Star is aluminum for good thermal transfer. (Hopefully, emitter slug is soldered directly to al...
    Cons:
    Not all emitter leads were soldered together when I received it (see pic in forum). (Not a big deal, but a quality control iss...
