Why is the term Nanometer” or nm used in describing our black lights?

A real black light bulb or tube emits 350nm + using gases in the bulb. A LED black light flashlight to mimic a true uv/black light bulb or tube must emit the correct wave length to correctly view body fluids. 385nm is ideal although the lower the number to 350nm the better the stain is seen. 385nm is cost effective compared to a 365nm LED “Light Emiting Diode” which is much more expensive and not necessary as the 385nm we find to be ideal. Most dealers sell high end 395nm-400+nm because the cost is cheaper however its difficult to see and reveal human and animal body fluids.
