Have you tried the Jetbeam BC10 XP-G R5?
It is related to the slightly bigger more expensive RRT-0 XP-G R5.
Selfbuilt has quantitatively tested the BC10 R5 and some competitors; the results are in the tables below.
In the first table using CR123 primary disposable battery at 3.0 volts, notice how the BC10 R5 has 260 lumens total output and the hotspot is 2750 lux @ 1 meter, such that it throw a whopping 105 meters till the brightness falls to 0.25 lux ANSI standards.
Notice how the Thrunite Neutron 1C XM-L has 310 lumens total output, has a hotspot only 1875 lux @ 1 meter, and throws only 87 meters till the brightness falls to 0.25 lux.
The 4Sevens Mini 123 R5 has only 160 total lumens by his measurements, and throw only 82 meters.
In the 2nd table using 16340 rechargeables @ 3.7 volts:
1) the BC10 R5 throws 167 meters!
2) The Thrunite Neutron 1C XM-L throws only 111 meters.
3) The 4Sevens Mini 123 R5 throws only 101 meters.
Theoretically, a Quark MiniX 123 with an XM-L emitter will have a greater total volume of light than the R5 version in the size of the hotspot and the brightness of the spill, but the XM-L version will have a less intense hotspot than the R5 version, resulting in even less throw than the R5 version...
