    Large array of 5mm LEDs (555 timer,LED flasher)

    I'd like to make something similar, but my leds are 4 serial conected (together have 5W). 20 pieces of this kind I'd like to connect in parallel, what means all of them would be about 100W, all supplied with 12V dc. What modification do you suggest? Thank you very much.
