I have a simple 4 led on 555 project but it needs to run on 24VDC.
1. power the 555 using a zener to drop the voltage down to 12V then switch the LEDs in series using a MOSFET and 4 220 Ohm resistors to distribute the heat.
2. Use a DC-DC to drop tp 8V and switch LED directly in series.
Anyone have a better idea?
