Came across your video as I am looking at building a 365nm UV LED display light for Fluorescent minerals. Of course I would need a filter to block out as much light that is viewable. Can I ask what UVB LEDs you are using and where you purchased them, I see some on Amazon but not sure the quality and if they are true UV at 365nm. Great video.
OSRAM modules from Mouser 🙂 - They’re expensive though keep that in mind :) These modules are as close as you will get to real UV spectrum, adding a blocking filter will get rid of anything left over :)
