I am building a circuit with 6 parallel LEDs, powered by 5 volts through a transistor array which can provide 300ma. If each LED is allowed 20ma (by setting the correct resistance for each), I should be able power each LED without a problem. I could even power 12... or 45 LEDs with 1 amp.
Is there anything that limits the number of parallel LEDs that I can power in this manner (besides power consumption?)
Will the voltage drop of one LED impact the others at any point (or would this ever be an issue?)
