Great review — but here’s a question: Does this light drop in output the longer you use it like seemingly all of the rest of the modern lights it is up against in this category?
IT does indeed, as one has to expect from any light that can produce a good amount of heat on Turbo. The good thing is that it is thermally controlled and not on a timer. I really hate doing runtime tests (probably because I don’t have the equipment to automate it) but Selfbuilt tested his and with no external cooling it didn’t step down until more than 10 minutes in Turbo. With a fan blowing on it he got around 20 minutes in Turbo.
Because the price difference from the TN40, is about $70.00,I think that there is not a charger in the package.I think that I will buy this one if there is some coupon from Martin.
—> The German forum tested/measured throw at 5 meters. I think this is not enough distance to test the throw of multiple emitter throwers.
So, your measurement will be closer to reality. Which makes this light even more impressive!
(Almost) every light benefits from bridged springs, but especially those that use only one cell (low voltage), those that have multiple cells which are parallel (also low voltage) and those that consume so much energy that they would burn the springs (in that case the springs act as resistors).
For me this is a standard “light mod” on all my “low voltage” lights.
.
Example: my Olight M2X UT Javelot stock with one 18650 did around 110Kcd.
With bridged springs it does 143Kcd. (with two 18350 it does 164Kcd).
Nice improvement with little work.
.
Good luck!

Because of amazing reviews like yours, thank you , I will be buying the Thrunite TN40S in the next couple weeks. Wish I could afford the TN40. Does anyone know where the best place is to buy this light or if there are any codes coming up for it. If not I am just going to buy it from the Thrunite wed site. I feel even at 189.95 it’s worth it. :heart_eyes: This will be my first real high lumen flashlight
I have a TN40S,with 4pcs 30Qs in it.I had measured it with two luxmeters,and found 313000Cd.Wanting something more,I sent it to a BLF member to bypass the 4 springs,and when I measured it again after this bypass,I found less Cds,ie from 263 to 285Kcd.The batteries were full charged and these measures,done with two luxmeters also.
Any suggestions?
It won’t increase output , but it will increase efficiency (lower resistance , so driver will deliver the same amps at the leds , and it will draw less amps than before from the batteries) .
