| - You are connecting to the INPUT of the strip, not the OUTPUT. This is incredibly common mistake. It wont work unless data is going into the correct end. Check the tutorial to see how to identify the input side. Just because your cut strip has a connector does NOT mean its an input.

| - | For long strips, there can be a significant drop in voltage from one end to the other. For strips longer than 1 meter we recommend feeding power to both ends of the strip. For very long strips (5 meters or more) you should plan to feed power to multiple points along the strip. | ||
| - | Mysterious Green Flash- On some strips it has been reported that the first pixel on the strip will flash green whenever commands are sent to this strip (If you are sending commands continuously, it will be green most of the time). We are still trying to understand the cause of this phenomenon. In any case, it does not otherwise affect normal operation of the strip. | + | **For long strips**, there can be a significant drop in voltage from one end to the other.
