Yes but it’s actually not really a huge difference. Half the lumens doesn’t mean you’ll see half the output, just like 4000lm is not twice as bright as 2000lm. That is VERY evident using the TC20…
When going from high (1800lm) to Turbo (3800lm) theres a noticeable difference, but no where near twice as bright, and about the same difference you would see between it and the V6 Catapult.
There’s been some posts on the subject before, the “perception of luminance”
- “it takes 4 times the lumens to see a doubling in brightness”
- “a perceived 50% lower perceived brightness is more towards 18% of actual luminance”
.
The emitters used in today’s dedicated throwers (XP-L HI, XHP35 HI) do not produce the higher lumen output of XHP50-XHP70, but the XHP50-XHP70 cannot throw as far due to their floodier beam with larger hot spot.
In fact it was the bright floody beam with limited throw of my TC20 that put me on a quest to find a good, somewhat compact size thrower: Discussion of compact size production throwers 700m+ under $60
.
Instead of carrying two separate lights as Rambo007 described, several manufactures have designed models that combine the two beams into a single light, Niwalker may have been first several years ago with their NOVA MM18.
The MM18 has seen upgrades to the MM18II and now the MiniMax MM18III, plus a little brother added, the MiniMax MM18JR
More recent ones currently in the works are the Astrolux MF03, and the Manker MK39 Ranger (my personal favorite)
There’s also the upcoming fan-cooled Acebeam X70
