Well, in this case I would expect the board not to work with only ~2.5V due to undervoltage thou...
2. If it's a Vader blade, it has red LED's. They have a lower threshold voltage than blue and green, so the LED's have a resistance in series wo Limit the current. So if you measure directly at the terminals of the LED's, you will end up with ~2.5V.
