Advice please, on building a 365nm UV head for Tool AA kit

You should be able to just use a LG UV led as a mcpcb emitter swap.
The tool driver shouldn’t produce enouh current to hurt it if your using a copper mcpcb.
Djozz was kind enough to post up his test of the LG UV led.

LG 365nm UV led tested (LEUVA33W70RL00, from Simon)

Simon only sells it already reflowed on a 16mm copper DTP board and that is how I tested it. Unfortunately they (I ordered 2) were extremely dirty, so I had to do extensive cleaning of the die (tissue and isopropanol) before I could start the test. Here’s the two boards that I bought, the left led I already…

I have a AA tool that I swapped in a LG UV led in (from Simon) and it works great with either battery type, it even has the original modes to play with.
Modes are not very useful to me in a UV light but thet’re there if I need them. The flashy modes in UV light seems a little weird and cool at the same time.
