it seems to me that the need for a "driver" is pretty dependent upon the application of your LED's.. Can somebody tell me if that completely ignorant or if im on the right track? Im not using a battery, my circuit is on a DC, and the voltage drop of my (4) LEDs is slightly less than my supply voltage... ive wired them in series and im currently running them with a small resistor and it works great. But i am looking to replace these with some higher output LED's. The voltage drop of the (4) LED's im considering would still be lower than my supply voltage. What, if any, are the advantages of running drivers with these?
Cheers,
