The SKD Series 1-3Watt isolated LED Driver original CC is 280mA. To change the R1 you can get different output current. Such as 3R3 ( 0805 1%) for 200-210mA, 3R ( 0805 1%) for 220-230mA, 2R7 ( 0805 1%) for 240-250mA, 2R55 (0805 1%) for 270mA.
Please pay attention that it is SKD type and it must be soldered up the transformer and capacitor yourself. We are not recommended that you did not know the technology very well.
