Current Limiting Circuit 1W 350ma Power LED
1w power led for rides so easy a handy circuit a few resistors and two transistors is done with MOSFET with 350mA current limit because 1w LEDs used in the circuit used IRFU9024 P channel mosfet instead of similar interventions in any P channel MOSFET can be used.
