  • Excellent but needs mods to work properly

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

    Pros:

    1. Led and heat sink are good quality. Wf501b gets hot but not too hot.
    2. Driver board supplied is ok too. Draws 1.1 amp at full. So 4 watts.
    3.. Runtime of 1hr at full brightness after which it starts dimming. Panasonic 18650a 3100mah from dx.

    Cons:

    Why was this led hand soldered to star in an application like this?
    Poor quality of wires used from driver to led. Just terrible to solder.
    Driver was not bad. Changed with sku 12768 immediately.

    OtherThoughts:

    Dx please ask your vendor to reflow solder the led with lead balls soldering paste as per cree data sheet. Led will be damaged by hand soldering so incompetently.

    Brutalized hand soldered led was sitting at an angle, raised on one side. Probably soldered by a kid in candlelight.

    I had to hand solder this properly.

    Bottomline:

    Buy this.. Value for money. But be prepared to re solder if you do not like co et tails in your beam image. Led is only 5mm across so this will be difficult.
    Also get another more powerful driver for this. Sku 12768 is a match.
