Got those TIRs in from AE. Sticking with my LEDIL for now. They need a small amount of filing/sanding of the flange diameter to fit in the bezel, but they fill the opening perfectly. Throw was 16kcd with a domed 4000k SST20 vs 20-21 with the LEDIL. Cleanest corona by far imo of all the clear spot optics I’ve tested. There was an odd non-uniform shadow in the center of the hotspot thought that put me off. The pebbled optic creates a beautifully smooth beam, but killed cd/lm too much for my needs.
I’ll tinker more with these another day but wanted to give some feedback for those waiting.
Overall, I’d recommend the LEDIL FA10661 with the holder removed and sitting on a standard XP 5mm butterfly gasket. Cd/lm is on point, beam is acceptable unless you obsessively hunt white walls.
