    Works well

    posted by nevik on 10/16/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Good efficiency. I measured 81-83% over an input voltage range of 6-8.4V. Measured output current is virtually constant at 2.35A over the 6-8.4V input voltage range.
    Cons:
    No markings to indicate the input voltage polarity connections. Inductor is bulky and oddly positioned.

    does the job...for now

    posted by zrinscak on 05/10/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    -good driver for a SSC P7 led emitter -variable input voltage (up to 8.4 volts), meets most of the needs for DIY projects with SSC P7 or MCE emitters
    Cons:
    -current measured at tailcap is around 1.2 amps at fully charged trustfire 18650s, which means that the current delivered to th...

    Good driver for the price

    posted by Mattaus on 05/05/2011 Certified Owner

    Involvement:Novice  (still getting used to it) - Ownership:1 day to 1 week

    Pros:
    - Pre-wired - easy to re-wire - good build quality - can be modified to work up to 16V input - easily drives 3 XM-L T6's in series
    Cons:
    - Not 2.8A as many have already said here - Changing that capacitor over is difficult - the inductor on the board makes it take...

    Good, but...

    posted by sigrm on 03/24/2011 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    It does most of what its suposed to. I bought it together with an SSC P7, which it is "designed" to work good with. Together with the P7 this provided powerful light, but it could have provided even more.
    Cons:
    I measured the output to be 2400mA, not 2800. When i connected it to the SSC P7, i got a reading of only 1,3A... Together with...

    Usefulness that everyone else has missed

    posted by royfellows on 02/26/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    This driver will power either a single or 2 serial wired Cree XM-L at 2.5 amps. This is the maximum safe level in my opinion, read the Cree data sheet re "Thermal Characteristics" 2 serial wired XM-L T6 will output 1600 lumens at 2.5 amps, and thi...
    Cons:
    Size matters as they say, and considering the electonics it could be a lot smaller. Its dimensions could present problems, and ...

    Pros:
    does what it says.... sorta
    Cons:
    2.4A.... not 2.8 ? I took measurements on 2 different p7s and it was the same. actually fried the driver which came in my coppe...

    Universal constant-current

    posted by siberianbat on 11/01/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Simply schematics and simply adjustment. Can work up to 16V, but You must re-solder C1 capacitor (look main picture) to 10mF x 16V You can adjust the current with a resistor near to C1 (marked R10 = 0,1 Ohm on picture) to get more current set lower resis...
    Cons:
    If You wish to get more current,- You MUST to resolder Schottky (D1) with true 3A Schottky diode.

    Cheap enough

    posted by old4570 on 01/10/2010 Certified Owner

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

    Pros:
    So far so good , Im over driving this driver by using 3xAA carriers or 11.73v measured at rest . There is voltage sag under use , so that could be very good . Measured at the tail it draws a little over 1A in my 3D SSC P7 Maglite
    Cons:
    Larger voltage input range would be nice , but so far none really .

    Not full 2.8 amps, but excellent module

    posted by HouseofStrauss on 08/02/2009 Certified Owner

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

    Pros:
    * Useful device and cheaper than building your own. * Samll size fits easily into projects as well as flashlights * low heat generation, although should be heat-sinked. * wide input voltage tolerance, makes it flexible in many designs
    Cons:
    Not a full 2.8 amp output from my module. I measured 2.33 Amps at 6.2 volts into a SSC P7

    Reasonable Preformance

    posted by budy500000 on 04/27/2009 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day

    Pros:
    i did not notice a difference in brightness in my spider fire p7 when using this driver vs driving the flashlight threw a 2ohm resistor using a 8.4 volt rc car battery. the driver is more efficient than the resistors i was using. (the 20w resistor got very ...
    Cons:
    driver does work as is but could be made better by the addition of a low value ceramic capacitor parell to the large electrolyt...
