Banknote Flashlight for Coin Shows

What type or brand of flashlight do you take with you to coin shows to examine banknotes for creases, folds, etc.? Links to specific products would be appreciated, if possible. Thank you!

A light with a broad diffuse beam will be great for looking for creases. You need to hold it from the side like so:

This is mine:

It does different colours also, which is good for some notes:

1000 Intis - Peru – Numista

Good tip :)

I just saw they released an updated model of that flashlight, with better controls. The IF24.
