Maxibright Daylight Power Cable
If you want to control multiple LEDs from the same controller, use the above-mentioned cable to connect the first LED and then use daisy chain cables to connect the rest of the fixtures together in a chain. For example, if you're running three LED grow lights, you'll need one controller cable and two daisy chain cables.
If you have one of the original V1 Maxibright LED fixtures, you can use these cables to place the bars in different areas of your grow space.
