Size: 46 mmx23mmx10mm / 1.81 "x0.91 " x0.39 "(inch)

1. The Fixed turn the lamp current to 0.1 times the value of the constant current (at the when 2 identify been the 'is full);

2. Increased input reverse polarity for protection, diode;

3. Using dedicated reference for IC, and high - precision from the resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1 a, when the temperature drift of less than 1%).
