Preferences? Mounted units? Handheld? I use a 16 LED blacklight. At times yellow and green can be confusing. Red orange...even pink orange. UV effects are an often unexplored aspect of note collecting.

At home I have a cheap ass handheld shortwave UV fluorescent lamp, with it's 254nm UV-C wavelenght it isn't optimal for most banknote security features.

The decontamination unit in our lab has a beefed up version of it and may yield better results.

But I'd really like to try a UV-A emitter to see something like this
