can anyone help me to power 44 led in series
i have total of 44 led connected in series
but i cannot make a suitable power supply circuit

 

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...
