I am looking to connect 10 480w LED grow lights (SpiderFarm and Kingbrite bar lights) together to one power source, daisy chaining to a power sorce. They will be daisy chained to a dimmer controller, but that is not the power source. The following diagram gives an idea of how they should be connected. The problem is, I am trying to find out where to buy the rights parts. This link on Amazon gives an idea, T-Connector but will they work?
I need help from anybody who has done this before.
The next question is what timer would you recommend to control these lights? I can split it to more than one power source if required.

The bottom connection would connect to the lights

First you need to get your actual amp draw, not the output that the lights tell you they are, but the actual amp draw of each. Then figure out your total wattage and amp draw. Then buy the appropriate amp connectors and the proper circuit supply wire to support those 10 lights. 1000 ACTUAL watts = 10 amp draw, always allow yourself more capacity than actual draw.

As a LED grow light manufacturer and designer, I recommend being careful when connecting a lot of powerful lights. Daisy chaining for dimming is usually okay, but when it comes to power, don’t try to run too many lights from one plug or outlet that can be unsafe. It’s better to split them across different power sources.
The T-connectors you found might be fine for dimming wires, but they’re probably not strong enough for power connections. Always use parts made for high-power equipment.
For a timer, choose a heavy-duty one that can handle the total power of your lights. Regular home timers usually aren’t strong enough. Using the right parts helps your lights work better and keeps everything safe.
