Q. Would you be able to run two of these in parallel or series circuit with 2 x 1.5v AA batteries? They only need to be bright enough for the eyes of a metal bug project.
A. Hi Harry, thank you for your question. The minimum voltage these work as is 3V so two 1.5V batteries in series will give 3V and then wire this to the two LEDs in parallel but this is the bare minimum they will operate at.
