There are many controllers that will control them. You may need to run them from 5v and the controller from 12v though depending on which one you get.
The big question is how many strings do you have, and / or, how many channels do you want to control?

Basically any dumb rgb controller will switch them.
such as

All of these will run the lights. But what you have to do with the first 2 is run the controller off a 12v supply and connect the rg and b wires to the controller and then connect the white wire to a 5v supply, then connect the earth wires from the 2 supplies together.
There are diagrams of this in the wiki I believe.

Depending on how many of the lights you are connecting you will need to be aware of the current capability of the controller and the channel. Those nodes will be about 1A per colour if you connect all 50 so most controllers can do that no problems. If you end up with more than 50 in a string then you need to make sure that the controller can handle that. Similarly as a string is 3A total when on white you have to make sure that if you have multiple strings off the 1 controller that it is capable of doing that. The 27 channel controller that Scamper linked to for instance is only rated to 15A so you would be limited to 5 strings of 50 (without doing mods).
The mega60 that Scamper linked to can also do some cunning stuff in that you can run the 5V nodes off a 5V, 12V, 24V or whatever power supply.

Hi,


Thanks for the information, I only have four 50 count strings so far. I'll check out your recommendations.
