I am powering two LED fans with a 4.5 VDC 600 mA. wall wart instead of three AAA batteries.
The fans spin a bit faster compared to using three AAA batteries that the fans were originally designed for. After 3 hours the LED's burn out.
I think the current is too high compared to three AAA's.
If this is correct how can I reduce the current?
BTW... I added a zener diode but now the voltage is 3.7 VDC.. too low to make all the LED's light.
