    Hello all.

    This is my first DIY led project and having done enough projects of other types I know its better to ask those in the know before spending $ and having cost blow outs etc.

    Now I am handy though I don't have a lot of tools.


    My plan is to attach 1pcs CXB3590-0000-000N0HCB35G - Cree

    Stats for item
    34.85 mm x 34.85 mm x 1.7 mm
    Color Temperature
    3500 K
    If - Forward Current
    2.4 A
    Cree, Inc.
    Vf - Forward Voltage
    36 V

    to a CPU cooler which I will bond with thermal paste and Kapton tape


    The base plate of the cooler is perfect size for the Cree chip

    This is the driver that I was intending to use but this is were my knowledge is seriously lacking :

    1pcs LPC-100-1050 - Mean Well - LED Power Supplies 100.8W 48-96V 1050mA CC LED

    My concern is the chips forward voltage is 36 but the driver is 48-96?

    I would appreciate any feedback especially in reference to the driver match for the CXB3590.

    Cheers Guys

    Vf is minimal to illuminate. Beyond that, the chip dont care. Amperage determines intensity. The heatsink is overkill at that drive current imo. Your only looking at 35-40 watts +/-, for the same price, maybe less you could go with a passive pin fin. Also, that driver could run 2 chips if you wanted. Wire them in series. You would get more out of it if you ran 2 50v chips, vero 29b. Im pretty sure it would drive 2 of those. Theyre prlly cheaper too.
