I just picked up an Evergrow 160W wifi controllable LED. It bugged me a bit having the wifi there with its own funky network name and that I can't control the wifi channel as we have a lot of interference here.
Some poking around and I found that you can get to a web interface for the wifi router part of the light, then from there you can change things like the SSID (network name) and password. I only spent a couple of minutes on it, but it looks like there's a chance that it could be setup to join an existing wifi network. If that's doable, that would make it much friendlier to live with. I'd imagine the same thing is possible with other brand wifi controlled LEDs.
In simple terms that means that I changed the wifi from broadcasting out a name of "UTR-1K59" to broadcasting out a name of "Reef". If you have multiple lights, you could call one "left" and the other "right" or whatever makes sense to you.
If you'd like to take a look at this on yours, you need to connect to the lights wifi like normal. I connected from a PC, but this can be done from a Mac or phone / tablet. You then need to find out what the IP address is for the light. Mine was 192.168.16.254. No idea if they are all the same.
From a PC you can find out by opening a command prompt and typing ipconfig /all and hit enter. Then in that output, look for your wireless adapter info and look for the DHCP server.
From a Mac you can find out by opening a terminal window and doing a ipconfig getpacket en1 and look for the server_identifier (ip) to get the IP address.
Once you have the IP enter that in a browser and for me the login and password were both admin.
From there you get a lot of basic router settings that you might be used to if you've setup wifi at home. You can change the network name, password, security type, etc. There are some mode settings there that look interesting as well.
I have no idea if pressing the reset on the fixture will put all this back, so be careful as it's possible to lock yourself out of the light or make it not usable in some other way if that reset doesn't put it back to factory settings.
The next thing I want to look at is it appears that the app talks to the fixture on port 8080. I haven't scanned to see if there are other ports involved. At some point I'll try to sniff out what is actually being sent back and forth. If that can be figured that out, it might be possible to control the lighting completely from a computer. If that were the case, it might be possible to create much more complex automation and controls for it.
