Here a UV induced visible fluorescence shot of another flower bouquet using Nichia 365nm UV LED and a 400-700nm UV/IR Cut filter.

and here for comparison the white light (5600K LED) shot
closer to see more details...
Well and here as another comparison, what happens when a Xenon flash with UV filter is used to stimulate fluorescence.
UV Xenon flash, but that leads to IR + red contamination as may be seen here:
and here now using a BG filter to compensate for that
but in overall comparison, the Nichia UV LED wins hands down IMHO!
Stay tuned, more will follow on that fascinating subject...
