    Pros:

    Good driver

    posted by kde11 on 05/04/2011 Certified Owner

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

    Pros:
    The driver works even from 1 volt (I'm not sure how much current it can produce from 1v, because I needed only 0.2A) and is very small.
    Cons:
    None. I gave 4 stars to build quality because name of IC was roughly erased.

    Pros:

    Cons:
    - Mode switching. I personally don't like it since mode can be switched accidentally. - Result current of 0.6A through LEDs (i...
