I am wanting to make a table lamp using LED lights. I am going to use a wall adapter to bring the voltage down to 12 volts. Looking at adapters i've seen they have different mA values(1A, 500mA, 800mA). Do i need to take this value into account when calculating the resistors i need to use??
I've done LED for automotive 12volt and never worried about the mA, just the voltage of the LED's into 12V and find the resistor value. So do i need to calculate this differently? If so, how?
