What is power injection?
Power injection refers to the concept of introducing new power to the LED lights after a long run of lights. Voltage drop happens because as power moves from one LED to the other, they consume power and pass less power to the next set of LEDs. This will vary based on the effect currently been run. Brighter effects will use more power and dimmer effects will use less power, leaving more power for lights down the line.
Connection Examples
Connection example using (4) Data and (3) power
This connection method uses multiple data points as the start of the line, with power injection after 10 tracks.
Other factors such as quality of cable , length , cable gauge will also contribute to voltage drop and reduce the amount of lights you can connect on a single run without power injection.
Implications
Cable wiring
It’s always a good practice to use cables with multiple connections. For longer distances, opt for better gauge cables, such as 16AWG. See some cable recommendations HERE
