Really it all comes down to the minerals used in the glass to color it. UV is Ultra-Violet reactive, meaning it appears to glow under black light.
What one calls CFL is not really anything. What this means is that the glass appears to be a different color under fluorescent light than normal white light. This is caused by the white light that is produced from a florescent light compared to the white light of say a LED light.
Color temperature Kelvin can also affect the way glass looks.
CFL means compact florescent, nothing more. So we use the term florescent transitional glass as it is the proper terminology.
