The only place I saw that sells 1072 wave lenght devices for a resonalble 'human' price is Cure Zone Ltd in Canada - you can contact them for a quote. They don't make the helmets but make LED arrays which you hold.
Just google Cure Zone Ltd to find them. I don't know if they ship to US or not.
People that claim that just
single LED's of 1072nm cost hundreds each might not be truthfull as the price seemed much much lower at that Canadian online store.
Hope that helps
