I am needing to put an external battery pack on a security light. I want to use a 4.5 AH 6 volt battery and connect it to the 3.6 volt internal battery pack. I am trying to use an
LM317T . By putting a 3.6 ohm resistor as R1 and an 18.6 as R2 I am getting 3.8 volts out. I need to get about 500 milliamps when the LED light comes on.This setup gets really hot. I am using 1/4 watt resistors. If I increased the resistors to 1/2 watt, would that make it run cooler?
Is there a better small inexpensive circuit that I could get the 500 MA with this 6 volt battery connected to the 3.6 volt battery?
Thank you in advance. I am running blind here.
