Since UV 1 is just a brand name, while it may be popular in certain locations, I don't think it's the definitive definition. Never heard UV 2 used before either (maybe a locality thing too but not as likely as UV 1) so I am going with the standard... UV = Ultra Violet as in light wave. Especially referring to lights.
