Experiment with RGBW XM-L

I have one of those color-changing led strips over my fish tank, and when it is set on “white” it really makes the colors of the fish “pop”. I want to try to replicate that. So what would happen if you took an RGBW XM-L and powered it with a standard Nangj driver, with all 4 die wired in parallel?

1. would all 4 die work at all if equal current was applied to all of them?
2. Would the light come out as a full-spectrum white, or as a nasty mix of the different colors?
3. would using a TIR optic combine the light better than using a standard reflector?

If the RGB was balanced it should yield white. But I doubt they’ll balance themselves just simply wired in parallel since they have different Vfs.
