I have a bunch of 5mm leds, wired in series of 3's with 180 ohm 1/4 watt resistors, powered by 13.8 power supply. When I shut the power supply off, most of the leds fade fairly equal except for one string of 3. In this series, the middle led fades out very quickly and the two end leds stay lit much longer than any of the other leds in the bunch.
Any ideas why this is? Just curious if I should replace the middle led before I finish mounting these.
Also just wanted to say this is the most educational forum that I have ever lurked upon, and also the most friendly toward newbies with newbie questions. /ubbthreads/images/graemlins/smile.gif
