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

    Pros:

    Cheap, has good quality MR16 pins, good silicone wires, small

    Cons:

    The input cap is useless. With the original cap I got 55 % efficacy with 2 blue leds and 12 V input (1 A output current). The inductor also gets quite hot. The dimming pin should maybe have soldering pad.

    OtherThoughts:

    Changing the cap to either good quality electrolytic or 10 µF ceramic got me 83 % efficacy. Also, for over 700 mA output currents the inductor gets very hot so replacing it is a good idea too.

    Bottomline:

    Good for the price and fits straight into some DX MR16 housings.
