Updated my UV-led test method (=final), tested a Luminus SST-10 365nm led (and some others)

It is there in the description:

But at that cost I am very skeptical.

90mW is way too much. The 5mm T1 variety will not be much over 10.

These Everlight ones have the same advertised output as the Vishay, but cost 30% less.
