I think there's a fundamental problem with producing a part like this. That kind of output at those kinda wavelenths is going to effectively "eat itself" very rapidly. UV does nasty things to both epoxy lenses and semiconductor junctions (why EPROMS are erased under shortwave UV). Making one isn't hard - making one that will last more than a couple of hours however, that is hard.
Someone may well get around this, but until then, the Luxeon Dental and Royal Blue are about as short as the wavelenths from Luxeons get.
