Strange that there's no option for XP-L dome on, only dedomed...
That's because it's using the 10507 20mm Carclo triple TIR optic. The inside of the optic cavity is designed for an XPG and is too narrow to fit an XPL with the dome on. Unfortunately, nobody makes a 20mm triple optic that fits an XPL.
To fit an fit XPL into a 20mm triple optic, one of the following has to be done:
1. Dedome the emitter - changes the tint, but without the dome in the way the optic easily fits in place. Gives a slightly narrower and throwier beam, but is still a very floody light. Dedoming reduces lumens maybe 15% while increasing throw by probably around 75%. This is probably the most common solution.
2. Modify the optic - Some people grind out the inside of the optic cavity. Just enough to make room for the wide XPL dome. This gives MUCH better tint than dedoming. Also gives a very wide floody beam. The downside is backscatter in the ground portion of the optic reduces total lumen output by approximately 20%. Mountain Electronics offers the grinding service on their Carclo optics if you wish to try this.
3. Squeeze the domed LED into unmodified optic - not recommended as any bump on the flashlight might cause the emitter to self-dedome.
