Dangit, there goes my calculation too. But, the efficacy of 4 emitters is higher than 3 emitters, so it’ less than 15A per cell you need…
Anyhow, I don’t think Imalent is even going to deliver 16000 led lumens…
Edit:
FYI, I asked Imalent: DT70 and DT35 have 4P cell configuration.
Of course. Just ball park figures; easier to calculate. Just like 3 or 4 emitters, meh, it’s about the same. So the conclusion remains: verrrrry unlikely.
Maybe they really did it like 220W input for 30seconds, then drop to 4000lm (25%) and due to low voltage and rapid high discharge no more 16000lm at all after that (literally impossible).
Since with the new ANSI runtimes that would be totally normal.
Surely is possible, just for 30sec total possible runtime from 4*18650, after all a pull of 220W from max 40W available (lets not even mention the 2.5V cells)
Besides I am assuming all max efficiency and all, reality may be different.
At least we know the flashlight can do 16000 ANSI lumen for 1hour and 30minutes, as the specifications say. Only when heated (50Celsius) the flashlight will drop to 1800lm output.
The second mode at 8000lm will work nicely for 2hours as it is rated.
This product sure is impressive, must output around 20Klm bulb lumens to be able to do 16Klm ANSI (which must measured at
least after 30seconds out the front). And it will not get hot in 30seconds to able able to get the 16Klm ANSI rating.
I’m more interested in the DN70. They claim 3800 lumens with one 26650. We’ve had a few 3000, 2500, 3200 lumens claims and they all fell short. Some much shorter than others. http://www.imalent.com/Item/Show.asp?m=2&d=198 Something tells me at 115 grams it’s going to over heat quickly on turbo. It’s low-20, medium-300 and high-2500 are getting the most usage. Banggood has them all it now.
This is getting ridiculous, over 10k lumens in the palm of your hand. We need a licence to carry these soon given the insta-flash risk to iris damage. The ministry of flashlight safety association(MFSA) will soon make an announcement regarding the application form at BLF . All current BLF members will be given an automatic exemption of course.
