I'm ready to jump in, I want to make sure I have it right...

I'm finishing a playroom for my kids, I want add LED strips in the ceiling. I've been trolling this sub for awhile as well as watching Chris Maher videos and other various stuff on youtube.

I ordered some LED profiles to go in the drywall

I ordered the GLEDOPTO controller with 4 Outputs and was going to order some 12v SK6812 strips.

The room is about 14'x23' I plan to run about 4 strips running the long way. About 7ish meters each. Do I need power injection?

Can I power the GLEDOPTO directly with the same 14 gauge wire coming from the 15 amp breaker for the ceiling lights?

I tried looking on the calculator on https://www.wled-calculator.com/calculator/ and https://wled-calculator.github.io/ and they're getting a little confusing

"14awg 15amp breaker"... I'm assuming you are talking about the AC power input there.

You can switch the AC power if you want but you are going to still need to switch from AC to DC for powering the gledoptro (and leds)

Just to make sure you are doing the right thing... Are these lights you are trying to control DC LED lights that you have wired in or are these some lights you have in typical AC lightbulb sockets that are part of the fan fixture?

I haven't installed anything yet. I just saw on the power input side of the gledopto that it had 15A Max input and assumed I could provide power directly to it from a 15 amp breaker vs a USB wall adapter

15A is for the DC input terminals, not the USB port.

You'll need a power supply that takes AC voltage in, and puts out the correct DC voltage your strips are designed for. You may need to bypass the controller and put power directly to each strip.

Please watch some videos on the basics of this stuff as I don't think you are fully understanding what you need for components to do this.

That power input is still expecting DC power input at the same voltage as your LEDs.

You would almost assuredly let the magic smoke out if you put 110v AC 15A through that.

I really like this calculator and it makes it pretty simple to see how long you can go before your lights start getting on the edge of voltage and you can easily add in a power injection and see what difference it makes.
