    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:Upon visual inspection when recieved, this is a high quality unit.

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week Pros:great price, bright, appears good quality and works well with SKU 3256 driver. Bit of warm one lit up, woa, it's only 29 C though I am not sure what's current from the driver. I used 6 V 400 mA power supply as input to the driver circuit. So with 80% efficiency, roughly 2...
