    What forward voltage are the leds, assuming they're 2.5V, then you will need 110V which is dangerous!!.

    Best to put them in series strings say 4 in series with a resistor, then put them all in parallel.

    Your first step is to find the specifications of the leds, like current or forward voltage...
