Interesting, but NOT full spectrum. UV induced fluorescence is VERY different to UV imaging. UV images are  quite difficult to capture with digital cameras:

A standard digital camera has no sensitivity to UV.

Most lenses absorb lots of UV, I can't measure any UV with my Panasonic lenses using the spectrometer at work. A few of my older lenses should be usable but only if longer wavelengths are blocked.

The older UV pass filters that block visual wavelengths all leak significant amounts of IR, which shows up on cameras that have been modified to increase their spectral range.

Intense UV light sources are dangerous! We have a source at work that can cause eye damage through UV absorbing glass!

My 'Full spectrum' converted GF2 still has very little UV response due to a thick filter stack. I'm planning on getting my NEX converted at some point for a better try.
