1.The system will achive optimization when the voltage of LED lights series between 230V and 250V.

2.Output current change by R1’s value; Bleeder current changed by R2’s value.

3.R3(AB) is a power resistance for reducing the power consumption of U2 FC2082G. It’s power consumption should below 1W.

4.The value of R4 suggested between 510K and 1M fordischarging resistance.
