LED lighting.

I was thinking of doing some thing similar to this.
https://sound-au.com/appnotes/an003.htm

But with a FET and a more symmetrical drive circuit such as an NCS2250 
comparator capacitively coupled to the FET.

So I can perhaps make it switch faster and more efficiently and with a 
smaller inductor.

I'm aware that this might sound crazy but it's just for fun and no-one will 
die if it doesn't work.

Since the parts aren't very expensive in small quantities I might get a 
board made if a simulation says it has a chance of working.

It will be powered from a 12V lead acid battery.
