    Excellent driver 15mm!

    posted by evgenic on 05/09/2013 Certified Owner

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

    Pros:
    The driver is made on three linear current stabilizers AM?7135. It is difficult to find a driver for LED 3W or more (for example,Cree Q5) I put in my flashlight Sipik68 (for a Li-battery 14500). During the whole battery charge gives direct current. Accordi...
    Cons:
    It is desirable that the driver (and consequently a flashlight) had two brightness modes: min-med 30-50%. For example, I have s...

    DX is sending the wrong ones

    posted by Flav_3 on 01/14/2013 Certified Owner

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

    Pros:
    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.
    Cons:
    I got the ones with only two chips and also waited two moths for arrival. DX did the right thing and fixed the problem though.

    Basic Constant Current

    posted by lukasandrysik on 10/20/2012 Certified Owner

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

    Pros:
    Very cheap, very simple It is basic configuration for those AMC 7135 integrated current regulators - basically there is nothing else on the board - just two! (in my case only two of them) AMC 7135 regulators and small capacitor. Nothing else These two 7135 ...
    Cons:
    Nothing, works fine, no necessary modes

    Pros:
    small, efficient for my needs, cheap and well enough made. very happy.

    a good regulator

    posted by epsilon519 on 12/18/2010 Certified Owner

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

    Pros:
    Has three AMC7135's. Simple easy way to regulate current to an LED. I like the fact the voltage starts at 2.7V. Nice when you are trying to drive a Red LED with out a voltage regulator too. Doesn't get too warm. Saves the LED. Allows batteries to last ...
    Cons:
    Only measured 580ma from it. Leads are thin and break off easily. only a 15 mm base.

    a real star

    posted by don-juan on 11/16/2010 Certified Owner

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

    Pros:
    Good circit board for modifying romisen rc g2. Fits without any grindingand it is easy to solder. just add q5 led and a 14500 battery and you have a real power flashlight.
    Cons:
    The only con i can think of is that the wire is a bit on the thin side but if you are careful it should not be much of a problem.

    Very good circuit

    posted by Aedazan on 05/18/2010 Certified Owner

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

    Pros:
    very small and works. It can be shaped with a grinder to fit into almost anything (may need a little resoldering). It doesnt heat up with extended use at all which means that it wont need to be mounted to a heatsink (as if anyone would anyway).
    Cons:
    The outer gold ring layer is too small for my liking but its still reasonably sized. the leads could be thicker as they break ...
