The blue LED revolution:

That article conspicuously fails to mention the wavelengths achieved (255 nm) so here's the information directly from Nikkiso.

Thanks. I was looking for that information in the article and was too lazy. 255 nm is comparable to the principal line of mercury vapor at 254 nm (2537A). That is quite a feat. I wonder what the package is.
