Question about Werkstein Schwarzlicht-Taschenlampe

The black light torch from Werkstein has no explicit indication of the wavelength in nanometres in the available data. The light range is specified as 0 m, which could indicate a special UV light type, but the exact nm number is not specified.

Typical black light torches usually operate in the 365 nm or 405 nm range, but no specific nm specification is available for this model.
