There is a bit more to LED(s) than meets the eye. Yes, size is important, but, my first question is what forward voltage can be tolerated? The second is; if the LED brightness actually a current controlled loop what is the forward current set for?
I have not sat down and done any detailed circuit analysis on the ergo infinity, but I didn't see any thing that was obviously a SMPS so I am assuming a pretty low forward voltage is required.
The third is; can anyone who has built one in the past tell me if the LED brightness is adjustable?
Wow Paul thanks for that. i expect you saved me a large amount of digging. now to mouser to select a color.
