    Quick help with DX driver

    Hi

    I have the http://www.dealextreme.com/details.dx/sku.20330 driver from DX. I have done loads of reading on this board and found conflicting info.
    What I have found is an input of 8.4v max and an output of 2A.
    Does that limit my options to a single MC-E, wired in parallel, @ ~500mA per die and ~3.25vf,
    OR
    2 x MC-E dies in parallel, LEDs in series, @ ~500mA per die, but 6.5vf. That will still leave ~1.9v to be used by the driver.

    So is what I said true or complete nonsense?!! Sorry but I had a brain fart thinking about these DX drivers!

    I have finished making the housing and need to rig up the wiring to complete it.

    Thanks

    I don't have one, but I have looked at that driver. It appears that it is to be used with a parallel connected LED. From the reports is will do 2.3 or 2.4 amps or so. That should give you around 600ma per die.

    I have it with 2 mce 2s4p with 2 18650 in 2s2p. All I can say is that it is BRIGHT! I haven't been able to measure the current as all the wires are tucked up in the housing which is v small. I built it really just to practice using my lathe as a milling machine. Turned out ok! Need to heatsink it to the bars though as this little beastie gets hot quick. May also put a thermistor in there to protect it.
