New lights are not recognised by coloursource 20

By identifying you mean figuring out the dmx parameters. Or RDM isn’t finding them?  The best thing to do is look in the manual if there is one. Followed by saving your show and starting a new blank one. Dummy patch dimmers 1 to like 40 and slowly go through raising each fader one by one and wrote down what it does. Sadly channel one may not be the intensity channel. And sometimes another channel may cause the entire fixture to have no output. Example if dmx 0 is the iris fully closed then it has to be above 0 while intensity is also above zero. Also post a photo of the lights please.  For the pars we have generic profiles for various standard led pars under folder generic that will likely work for the knock off pars. Hope this helps. 

I hope I am not stating the obvious but if you try Chris’s excellent suggestion to patch 40 channels as dimmers and see what each does, ensure the light is in DMX mode, usually having ‘Addr’ on the menu and this is set to 001. Yes, you may not get any joy fading one up at a time because if one is master dimmer and then there are intensity channels for R,G, and B, both master and R have to be up to get any red out of it. Likewise with other colours. A strobe channel can also affect the output, sometimes stopping the effect of the colours altogether.
I have some inexpensive LED spots that have one channel for master dimmer/strobe combined that from 0 to 50% raises a white mix from 0 to full, then colour strobe from 50% to 100%. Only with this set to 100% can you get steady colour control which I guarantee patching it as a separate dimmer at full using a Independent and patching the other channels as an RGBY fixture with the console providing virtual master dimmer.
