Yeah I was gonna point out that UV comes in many different freq.
UV is broken into Vacuum UV (40-190 nm), Far UV (190-220 nm), UVC (220- 290 nm), UVB (290-320), and UVA (320-400 nm). In general, shorter wavelength UVs are capable of more dramatic effects because they've got more energy.
UV LEDs are barely UV, around 395 nm (varies by model). Blacklight fluorescents (bug zapper lights too) 365 nm.
UVB is the big skin burner, but that's far off. Germicidal can potentially cause eye damage, but that's <280 nm.
I liked the blacklight-white tubes that don't have the purple filter glass, generate the same UVs, but let out visible light too so the room and project don't look all funky without additional lighting.
