  • Super cheap driver

    posted by ecotack

    It works on a single Li-ion or a 12v battery.It drives between 1 to 1.2A (depends on LED and power source)None have failed yetBoard diameter fits P60 drop-ins.
    I have used these on a single Li-ion torch and also in out side lighting on 12v (for our stables). Since buying my first last year, none have failed. None of my Cree Q5s have burnt out yet either, but good heat sinks are needed at 1.2A.
    Its a good cheap driver just to have around. I always keep a few in stock for those quick projects.If you do any torch mod-ing or are into efficient LED lighting, try these. Don't want to drive your LED at 1.2A, simply use 2 LEDs in parallel for 600mA each.
  • good as long as it worked

    - very small board- cheap- wide range of input voltage- keeps a minimal light on even when the batteries are extremely low, going into a kind of "low-strobe" mode
    I soldered two cables to the contacts on the back to connect it into a DYI bike light with sku.44306 and sku.5602
    I would buy this again for other DYI projectsIt would be nice to have better information on which driver to use for which emitter
  • DX is sending the wrong ones

    This will be a review for the 700mA board since that is what dx sent out. It is essentially the same product but with one chip difference. Quiet, constant and easy to solder to. Will run an array of emitters. Does not get too hot.
    Good for small projects.
    If the only difference between what I got and what I was supposed to get is the one chip, then I recommend this driver as it works as stated.
  • Good boost up to 1.4A

    You can get higher current buy resoldering R150 resistor to R100 (0.1 Ohm). To get more stable output add 10mF solid capacitor to both tantalum on-board (total 2 of 20 mF). I have done all above to drive Cree XP-G and get a small pocket sun 8-)
    Chip is similar to PAM2803.It can be cutted to 14+mm. (need to mod some tiny flashlights)
    Buy it! Seriously))
  • Excellent driver

    *Cheap*Keeps constant curren to LED*Many modes*Modes can be turned off and keep only simple ones*I love it because I can finally KILL those stupid modes like SOS or strobe and still have Low and Medium ones - It is really annoying when you accidentally switch in total darkness your flashlight into fast strobe mode!*With R5 LED it keeps constant current around 1A until the cell is around 3,4V and then slowly climbs down.*Undervoltage protection - when the cell is around 3V it automatically switches to LOW mode and blinks every few seconds. After some time it shuts down completly - It means you can use batteries without protection circuit and it won't hurt them
    Full is around 1AMedium is around 300mALow is around 50mAStar configuration No star: Low, Med, Hi, Strobe, SOSFirst (clocwise) star: Lo, HiSecond: Lo, Med, HiThird: Lo, Hi, StrobeFourth: same as no starAlso watch my videoI modded Trustfire TR 801 (sku13095) and now it has longer runtime and constant light output. With default driver initial current was 1,5A and quickly climbed down with dropping voltage. With this driver it is long time constant at 1A. Really recommended upgrade!
    Great driver, really recommended.
