I just bought an Inova X1 (http://inovalight.com/site.html?X1-ov) with a <font color="blue">blue</font> LED. This type of flashlight caught my attention after watching CSI because blue reveals things not seen in white light. So far, I've only been able to bring up florescent material (such as a highlighter). What can I do to make the flashlight reveal other things such as human fluid? I know that they have this orange glass, but I don't know what's it called (hence I don't know where to get it). Thanks for your help.
