Can I mix led and xenon lights?

I'm using 2 led Sunray 1200 lights and I would like to ad the 3rd one Sunray HID (xenon) light.

Would that be a good idea?

You should look into gel color filters, like those from Lee or Rosco.

The only problem with mixing lights is widely different color temperatures will look weird, but if you even them out using yellow color filters it'll look more natural like sunlight.

You should be doing that with strobes as well, since they're usually too heavy on blue spectrum and when you do white balancing it sucks out all blues out of the water background.
