All Fluorescent Pics are Labeled. Shortwave (SW) Pics were Taken with a 35w WayTooCool SW light. The Longwave (LW) UV Pics are with a Convoy C8+ 365nm LED Flashlight.
Fluorescent Response Will Vary Based on the Strength of Light Used, but Any Decent Light of the Proper Wavelength(s) Will Produce Similar Results.
Please Note: You need a Shortwave (SW), Midwave (MW) and/or Longwave (LW) Ultraviolet (UV) Lamp / Light to see the Fluorescent Colors as Show in the Pictures! This is NOT the same as a Blacklight, although there will likely be some minimal fluorescent response even from a Blacklight.
