    posted by oliverlensert7 on 06/08/2011 Certified Owner

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

    Pros:
    -great and simple mod to fix direct drive lights -small size -does not get to hot at 4.5v -does not flicker like a $20 driver i bought recently
    Cons:
    -gets very hot at 6v (max component ratings) - i blew one board doing a test (to see if it could handle 7.5v-it can't!)

    Fantastic mid range driver

    posted by gearhounds on 09/16/2008 Certified Owner

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

    Pros:
    Well made standard sized 17mm driver, works great with a single 18650 battery. Thanks to 3 AMC7135 chips, runs very bright all the way down to 3.4V or so before I could detect much dimming and still quite bright. In even a thin walled light does not make th...
    Cons:
    None. Zip. Zero. Some state that the number you need to buy is a con but I disagree. They just don't have enough places to put ...

    Simple and working, perfect for 4*NiMh

    posted by Bylborg on 06/12/2008 Certified Owner

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

    Pros:
    These units are small (17mm diameter, 3mm (approx) height) and easy to use if you have a good soldering iron. They provide good efficiency if Vin is close to Vout (4*NiMh with a 3.5 to 4.0Vf LED, for exemple). Reverse polarity protection is efficient and do...
    Cons:
    These circuit boards require proper heat dissipation. They are inefficient if the input voltage is much higher than the output(...

    They work well and are simple to use

    posted by Cheater512 on 04/02/2008 Certified Owner

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

    Pros:
    Dead simple to use and they seem to work fine. They dont get very warm while in use. I only noticed a slight temperature increase.
    Cons:
    I had to guess the pin out. Fortunately I guessed correctly. The center connection is GND for both power in and the LED. The ou...

    Inexpensive, linear buck drivers

    posted by chimo on 01/19/2008 Certified Owner

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

    Pros:
    -Inexpensive -Can disable/remove 1 or 2 of the 7135s if a lower current is desired -Thermal protection works
    Cons:
    -one of the boards had a mis-alligned 7135 soldered on -contact pads could be better marked

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

    Pros:
    Great little low priced regulators. Cheaper than many other boards that perform similar tasks.
    Cons:
    They only come in 10 and 20 packs. These require mid range input voltages.

    Awesome

    posted by joe-dm on 06/26/2007 Certified Owner

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

    Pros:
    Regulated 1A output from 3xD sized alkaline cells in my MAGLite. Current draw from the batteries was approx 900-1000mA.
    Cons:
    Only supports up to 4.5V. Would be great to have a circuit that output 1A and could take a supply of 9V or greater.
