You set too white color for absorption(in my scene it's have default value), and forget to change color for scattering(it was black, do not set it to pure white it will be very slow rendering this rule for all materials too)
also you have wrong absorption distance it's too much 660meters (in my scene 665cm).
It is better to keep both unit in the same scale, your scene is in mm but shows you in meters what may cause some problem, i believe size of light radius showing wrong value

Hi. Made a quick test with the numbers Sprayer posted, and it works very well. I've attached a small render + a file (max2014). A few Corona materials are used.

Hope it helps
