Control/Dimming Strip Lights / DMX Control?

[Opie]

I have an application where I needed to hide these RGB LED tubes inside of a shadow box. The small controller will change the colors to rotate thru them all.

I am interested in converting these to DMX control. Each tube has a plug with 4 wires going into it.

Could I use something like this and convert it over to DMX?

I dont need a ton of control. It's just for back lighting. I just want to be able to control the color, dimmer and on/off.

Thanks in advance!

You won't get a dimmer channel with that box. I have 6 of them controlling some wall 5050 LED up and down lights and all you get is a Rch Bch and Gch.
