I created a UV light for about $27

I created a specialized light from a Chanzon LED for UVIVF photography (ultraviolet induced visible light fluorescence). The diode instantly emitted plenty of visible light, which was dissapointing, but it seemed to give off lots of UV light at about 365 nm. So I decided to try and add a UV pass filter for about $5, which is about 20mm across, and taped it to one end of a pipe, and the LED to the other, and used super glue to keep each in place on the pipe. I then soldered two cables to the battery (they were previously soldered to the LED) and attached them to a nine volt battery. I know this alone doesn't put much experience in me as someone of maker skills, but it was fun regardless of that fact and I hope it will be more rewarding in the future. The light from this LED isn't the same as that of the usual blacklight, whether it be a flashlight, incandescent, or even fluorescent blacklight, which give off noticeable more purple light. Is there an even better alternative to this setup? Check out my flickr page for any upcoming photos done using this setup that was just described.
