Yes, I only know a bit about electronic
I don't know if it's call AC or DC.
I have a 3A led with typ 18V (min 17V and max 19v) and will put into my motorbike for off road. And I have a -5V 1A power supply.
If it's possible running led with positive and negative voltage, I don't have to buy expensive 3A boost switching led driver.
The motorbike produce around 13V when engine on. With -5V, total 18V. Now the problem my -5V power supply is only 1A.
That's the reason I'm ask a noob electronic question.
So... will it work?
