How Do Tapes Show Up Under Blacklight?

We often get asked how do different fluorescent tapes how up under a blacklight (and what do non-fluorescent tapes look like) so we took some comparison photographs to see. Below are some photos of different rolls of yellow tape and how they showed up for us (these were taken in a light tent with a blue background with a Streamlight 51010 UV Flashlight used as the light source against the rolls):

*** Our personal observation is that the fluorescent gaffers definitely showed up the best (especially outside of the light tent), but we did get the PC-619 yellow duct tape to fluoresce also. Outside of the light tent the effect on the PC-619 (polyethylene-coated cloth duct) was not as dramatic as it was on the 510-Neon (vinyl-coated cloth gaffers) though.
