I *think* you can do this using a kludge I used to get ICE color info into Redshift (but without the Redshift part of course!).
Basically: - instead of creating one instance master point light, you make, say, 11 of them, one at 0 intensity, one at 0.1, one at 0.2, up to the last at 1.0. (you could increase the "bit depth " of your range by scripting this to make, say, 256 different lights. I wouldn't recommend trying to do 16-bit lighting) - select the lights in order of intensity (this is important) and make them an instance group. Now their order of instance group index matches their order of intensity. - in your particle cloud, use rescale and a scalar-to-integer node to get your intensity range into the corresponding integer index range (in my example, this is 0-10). - Set your shape instancer to use the integer range to set the group index. So now, when you instance the lights, all particles having an variable value of 0 get the light instance with 0 intensity, the ones from .001 to .1 get mapped to .1, and so forth. Like I said, it's a kludge. But it works, and with scripting, you could have a fair amount of intensity resolution. You can also do this with RGB color by using 3 lights per instance.
