hi Im new here and I need you guys to help up.I had made a LED torchlight with 15
LEDs connected to it.The LED used is white in colour,5mm in diameter and all connected in parallel.I had recycle 3 of the lightbulb reflectors to fit to fit in the LEDs
at 5 each.now my problem is upon finishing my build I used a 9volts 250mA battery to connect it but found out the the light is not bright enough.can anyone of you guys help me up to configure what is the voltage and current required to power up the LEDs until to some level of brightness? I had been thinking of building a voltage inverter circuit from 4.5volts to 9 volts for my torchlight. welcome to share my project to anybody interested ......thanks
