I had a quick question about possible CE (and other problems) with an odd circuit for driving 1W and 5W white LEDs (350mA and 700mA) from 240VAC mains.
What are you views on the following. Have 350mA LED(s) in series with 1000mF cap from +ve to -ve within full bridge rectifier. So far so good. -ve of bridge to mains N. +ve of bridge goes through a 4.7mF "motor start" rated capacitor to main L. Is this legal? Will it run foul of CE regs. How do I measure the power efficiency? Many thanks Richard
