Hello, new to the forum. This looked like a good place to find the answer to my question.
I'm interested in building a custom Wii sensor bar powered by USB, and I have been looking around for the cheapest IR LEDs and I found a 3 pack on electronic goldmine.

Problem is, there is no voltage or current ratings on them, so I'm not sure if 4 of them in series is going to exceed the 5V limit on USB or if I'm going to need a resistor. Does anyone know the specs on these LEDs?
