    Any decent DX/Kaidomain 1A drivers?

    I'm thinking of building a cheap 1 x XP-G w/Regina helmet light, and it would be nice with a cheap driver to go with it...

    I did a search and came up with this:
    1A DX Drivers?

    Is this Kaidomain driver still a good bet?
    http://www.kaidomain.com/ProductDeta...ProductId=1640
    In the description it says both that it is a 1000mA and 750mA driver, but I assume that 1000mA is correct...?

    Are there any good alternatives at DX?

    The KD 1640 seems to always come in right around 1 amp. Good driver....

    The DX 3256 varies between 650 mA to around 1 amp. Good driver, just not the most consistent on current/design.

    If 1 amp is important then go with the KD driver.

    Yup - 1A is quite important. Want to squeeze out all the lumens I can.

    Anyone know the diameter of the Kai driver? The site doesn't say.

    Thanks for the heads-up

    Is this one of the DX/Kai drivers? Do you have a link?

    Yes it is the very one you mentioned in your link and indeed it is 1000mA.( my iphone does not take very good pictures it does not show the driver clearly but the micrometer display)

    As you can see I have it attached to a piece of copper using Arctic Alumina epoxy.

    DX SKU 26110. Output is 1.2 amps, so it's a good match for the XPG.

    Add a 1 ohm resistor in parallel to the existing 0.2 ohm sense resistor to bump up the current to 1.5 amps if you want to max out the XPG.

    Thanks folks! Lots to choose from here.

    But are any of the multi-mode drivers any good? I would want to feed it with 2 x Li-Ion batteries, so e.g. this one has too low input voltage:

    If you want a multi-mode driver for 2S Li-xx driving one LED, you can try these LEDA0712 based boards:

    3 mode, no memory: http://www.dealextreme.com/details.dx/sku.25517
    5 mode, no memory: http://www.dealextreme.com/details.dx/sku.26107
    3 mode, with memory: http://www.dealextreme.com/details.dx/sku.26111
    5 mode, with memory: http://www.dealextreme.com/details.dx/sku.26108

    What type/model switch do you use with those multi-mode drivers?

    Most of these drivers work best with a "reverse clicky" switch. A reverse clicky has a momentary off function - if you soft-press the button while on, it will turn off momentarily without latching the switch. It is the momentary-off which causes the driver to switch to the next mode.

    I believe all the switches on DX are reverse clicky, so take your pick.
