What resistance do Vex LEDs have? How low can the supply voltage go before the LED stops working properly? I’m using one as the load in a circuit, and I’d like to make sure I don’t damage it. I also want to know what my current draw will look like in my experiment.

It’s a diode, see the graph in this post.

Usually with a LED you must provide an external current limiting resistor. What are you trying to do?
