A tri-emitter light with a shallow(er) reflector will not out-throw a deep reflector flashlight. The TK75 provides massive output but it is flood output and not throw. You seem to keep confusing massive output with brighter when in fact there are all sorts of different beam profiles based upon the reflector. Want something that will light up your entire back yard? Get a tri-emitter like the TK75. Want to try and spot something > 800 meters away? You need a deep throw reflector. There is no best of both worlds, you either sacrifice flood for throw or sacrifice throw for flood. That is why people who want all throw go with aspherics which have no spill at all, and people who want all flood cover their lenses with frosted film.
The TK70 cannot out throw the SR90. The TK75 does have more overall output, but it is using shallower reflectors so while you light up a larger area the beam profile isn't concentrated like the deep reflector flashlights.
I compared my TK75 to my SR90 before getting rid of the SR90 and determined the SR90 had slightly more throw but less output. Your statement above would be fairly accurate when comparing the same LED types. Due to the huge difference in die size between the XML and SST90 it shouldn't be used to describe why the SR90 out throws a stock TK75.
For example if your statement was completely accurate my modified TK75 would not be able to totally outclass the SR90 which it does. The modified TK75 throws so well and puts out so much light it makes the SR90 look anemic. In fact my modified TK41 will out throw a stock SR90.
