General question : long thrower and lumens

Interesting question. Just some random musings, not authoritative by any means.

Long throwers, especially SUPER-throwers, are mostly of single reflector or single TIR design, immediately this means one single LED. And the output is of one single LED.

Flooders could be single LED, like my ex Thrunite T2 with nauseatingly green XHP70.2 LED, but it doesn’t HAVE to be. You could add multiple LEDs by creating multiple smaller reflectors grouped together and increase output. This is seen with the lights in this thread of “super lights”: $100 Budget MONSTER-Lights w/ 15000+ lumens: Wurkkos TS32-Nichia 519a. Comparison with Chinese POWER-LED Heavyweights: in Haikelite HK05, JKK76, Nightwatch NS59v2 Chaos. (Summary & measurements on P. 1)

Long throwers COULD be multiple LEDs like those super lights with powerful Chinese LEDs above, all with throws above 700m, but it then becomes a floody long thrower. Problem is IMHO the near field bright flood causes pupil to constrict so now you don’t see that distant spot as well. Meaning it doesn’t work well as a thrower and that’s partly why the best long throwers remain single LED design that shine far field only - bright central spot surrounded by darker spill doesn’t cause pupil to constrict.

There are some super throwers with multiple SBT90.2 LEDs that are not floody. But they are big lights and expensive. They exist, just are not common.
