How deep would a UV light penetrate? Seems like we could clean our blood by 
shining the UV light on our near skin arteries similar to a Beck zapper. I just 
had 3 UV blood cleaning treatments in Mexico and they helped my 
Allergies/Asthma. My Beck zapper did not work that well for Allergies/ Asthma. 
Still get 
Aspergillus clumps from my sinuses during flushes but they are smaller and can 
go 4 days without seeing anything. Could the 660 nm red led simulate the UV 
light?
