Hi, I would like to know what type of LED's are compatible with the YX805 solar controller chip. I have several garden solar lights with this chip and the LED's have appeared to have failed in them and if replacement LED's are dirt cheap, I would like to try to fix these as they are relatively new and have not had much use.
 
It’s probably not critical. You should match the current and voltage. The voltage doesn’t have to be exactly the same. You can use an LED at a lower current than its rating, which will improve life.

Most driver ICs have a resistor to adjust the current and it’s a common hack to reduce the current to improve life.
