Basically I have 4 LEDs, all drawing 2A each at a forward voltage of 4.5. I can't even imagine how to power these. I need them to be triggered by the output from a 555 monostable timer.
Am I going to be able to do this with 12V? I can't imagine that I would, considering that even if I cut the current to 1A each, I would need a 6 ohm, 36 watt resistor to be safe, and that's not considering the 555 timer or the transistor..
Even with a 24V supply, I can't see how this would work..
Any help would be appreciated!
