Can someone please make sense of this?

That led will work fine. In fact, 1D is my favorite of the cooler tints. The XP G3 offers a bit more output with a more robust die(no bond wires to melt or break), the XPL is an XML die on an XP footprint substrate(the HI means instead of a dome it is flat giving slightly less output but a tighter beam than non HI versions of XPL), and the 219C is another XP size emitter with a bit less output but low forward voltage and a very robust die(tough to kill and has a nice tint too)

Thanks. I like the idea of more rugged with more output.

Hard to go wrong with the current crop of emitters but it is fun to try different ones to see which set of plus/minus’s pleases you most.
