Re: College Acceptances and a Withdrawn Course

Re: DIY LED Flashlight/Spotlight

In your case, if you want to run them off 3x 9V batteries in series (ie, 27V) then you're best to put 3 parallel lots of 8 series LEDs directly connected to the batteries (giving 3.4V to each LED). Then put the remaining 3 (if it's practical) to just one of the 3 9V batteries making up the 27V. If ...
