Black Light? - tanTALK

This may sound odd, but would a simple black light tan the skin? After all, it does emmit long wavelengths of UVA which penetrates deep into skin to tan right?
Thanks for any info!

No,
You need both UVB 290-320 nanometers and UVA 320-400 nanometers in odrder to develop a tan
visible light is 400-700 nanometers
