My current project includes a circuit with 3 940nm IR LEDs to be put on a glove. The LEDs are in series with a resistor and they are powered by a 9V battery. The LEDs are tracked by a Wii remote IR camera. It's important for the project to have 3 LEDs because they make a shape used for position and …

Power IR LEDs + 9V battery + eye safety = possible ?
