Are you in a country that uses 110 or 220 volts? That, along with what your Amp rating is on your circuit breakers will allow you to know the stress you are putting on your wiring.
As part of your concern, you mention running two Kind LED K5 1000 XL LEDs. Based upon their website’s info, they each pull 650 watts of true current. That is a total of 1,300 watts, should it all be on 1 breaker. To give you an example about power draw, that would be like running a very powerful microwave oven non-stop from 12 - 18 hours per day. (The standard microwave that most recipes take into account is 1,100 watts.) To give you an example, I’ve blown a breaker running a 1,300 watt microwave and then turning on a dishwasher tied into the same circuit.
You may wish to ask an electrician, or find out what each or your breakers can handle. You could also run each light off of separate outlets, that go to different breakers.
What makes this a difficult question is also, the unknown about the wiring in your house. Some houses have better wiring than others. Older houses may not have wiring that meets current safety codes. There are a lot of intangibles to consider.
I used to be responsible for setting up and mainting broadcast studios and control rooms, and ensuring nothing crapped out in the middle of a broadcast; however, we always worked with ideal state of the art conditions and schematics laid out by qualified electricians. Your best bet, imho, would be to have a full understanding of the way your house is wired, and maybe check with an electrician. You could hook everything up to an circuit that can handle 30 amps, yet even then, you need to ensure your wiring is able to handle the load.
There’s just a certain level of safety that you need to take into account when hooking things up to outlets. Regardless of whether you are in a 110 or 220 country, it is doubtful you run all of your electricity off of one breaker. You really need to know your layout.
I hope it works well for you. Hopefully others will chime in.
