The wavelengths emitted by these lamps is commonly referred as blacklight blue. It looks purple and is relatively harmless.
An uncoated Hg distented vessel of quartz, when biased with EMF of sufficient pressure to ionise the Hg vapors, emits UV-C at 260 nM and is quite dangerous especially at higher current drive / internal pressures. Frequently, these emitters are used as germicidal cleaners, rapid UV cement curing devices, and for low level production of O3. This is commonly referred as shortwave UV. Your coated glass CCFL lamps produce longwave UV and are eye safe.
