Well, I have done an output test on that LiteOn led a while ago, which has the convenient XP-footprint so you can use it on a Noctigon, and it has by far the best output of any 3535-size 365nm led that I have seen (and significant more than the Nichia 276A for that matter), and for a very good price. The current sweetspot on a Noctigon is 1.2A. It does emit some white-ish light as a side-product but that is no point at all for curing glue (and that can nowadays simply be filtered out with a cheap ZBW2 filter if you want to get rid of it)
