Wanted: LED UVC DIY success

Anybody look into doing a LED bank that emits the 260nm wavelength? I did some reading and it seem like this could be an option - even saw an internal filter that had 4 LEDs in the impeller housing.

I am not sure how many LEDs one would need for a compact add-on to a canister return or even an internal powerhead with low flow rate. Then again finding a supplier for the LEDs could be an issue.

But could be an option - lower power consumption / less heat.
See http://en.wikipedia.org/wiki/Ultraviolet for a good article on UV and http://en.wikipedia.org/wiki/Ultraviolet_germicidal_irradiation for UVGI.
