Summary

English: A cheap aluminium LED flashlight emitting violet visible light as well as UV-A/black light (probably not below 380 nm though). Can be used for checking bank notes, reading "invisible ink" etc. This specific one was bought to “de-yellow” an old Takumar lens, results can be seen here.
