Screen sync RGB lighting?

[ArmageddonA]

There are plenty of companies that make LED lights that sync to your screen and provide background lighting effects based on what is shown on your screen via a linked box through HDMI. However finding items like this in South Africa is hard. As far as I can tell you can only get them locally via takalot from a brand I have no experience with. The other options are Lytmi and fancy sync box.
I'm not sure about which one to buy or if they are even worth it. Is there anyone who has any suggestions about this?
