FAQ:
Q: Is there a 3 volt power adapter for LEDs?
A: These regulated adapters will put out exactly 3 Volts of power if you hook one single LED to it, or hook the maximum number of LEDs to it. They are regulated and able to run delicate electronics. These UL listed Adapter / Transformers convert wall current to 3 Volt DC output, perfect for our LEDs.
Q: Can you use a non regulated 3 volt adapter?
A: By comparison, A non-regulated adapter can put out up to 5 volts of power, which is too much for 3 volt LEDs. We do NOT recommend connecting our 3 Volt LEDs to a non-regulated adapter as the potential output voltage would be too high.
Q: Can a 3 volt adapter be changed to an AA battery?
A: Easily change from 3V wall adapter over to battery and back! If you like to run your lights on wall power, and still want the flexibility to sometimes run on AA batteries whenever you are not near a wall outlet, we have a solution.
