LED light can be about as far as it’s possible to get from a blackbody spectrum, if similarly to that is what you care about (I don’t, art galleries do).
There are two ways of doing “white” with LEDs:
• Separate red, green, and blue, whose spectrum is spiky: https://en.wikipedia.org/wiki/Light-emitting_diode#/media/Fi...
• Phosphor, which may give you a spectrum like this: https://en.wikipedia.org/wiki/Light-emitting_diode#/media/Fi...
