Can I also select if it will be a blackbody/spectral or RGB light (so I can make fluorescent lamps, neons and hot lava?)

Make a wish list. I'm not going to remember all this.

Well, you have it. Only thing I really want, is to have the physically correct lights Lux provides:

Blackbody (physical emission spectrum - enter temperature)
Spectral (spectral ones, enter a spectrum, get a light, can be used to make realistic fluorescent light)
RGB (now this is the type of light Poser has, it has a color. Usable for colored lights)

(IES support would be nice, but that can wait v2).
