If your measurements are correct, the T3’s new driver has a very poor efficiency
T3 100Lm / 2,1A
T2 115Lm / 1A
Is it possible that you accidentally swapped the 14500 / AA measurements?
I wanted to buy from the new driver so far, but this is disappointing. I also don’t like the fact that the output is as poor with 14500 as with AA.
Hello forum,anyone have experience with SFT70?,i’ve seen video of SST70,but none of the domeless version. I have one on the way,along with convoy xhp70 4,8a6v boost driver. Planning to set the led in my M21d. Any insight would be very helpful
Cheers
Affected by the accuracy of the chip and the sensitivity of the human eye to the difference in brightness. I estimate that many people do not feel the brightness change between 1% and 3%.
JaredM's findings indeed agree with what I also found in a CSLPM1.TG build I made long ago, soon after led4power started listing these leds at his store. I ended up driving the CSLPM1.TG a liitle above 6.5A or so (measured), by means of modifying the Convoy regulated linear “8A ramping driver” replacing its stock R005 sense resistor with a stack of R010 plus R025 plus R050 in parallel sense resistors.
In that picture most stupid thing is to cover flashlight cooling fins with paper. On my M21B FC40 thermal control work fine. Without cooling the temperature never excited 60-62°C

If you dont go with second turbo it is safe. Also at 35% temperature go max around 55°C. With cooling or on bike 35% or 50% is safe also turbo without any second activation.
The product page says it’s limited to 55C. If yours reached 60-65 that may not be outside of safe temperatures, but it doesn’t mean the thermal management is working correctly.
I’ve seen reports of L7 and 3X21A having the same issue in their respective 1Lumen reviews. This trend of nonfunctional thermal management in Convoy lights is concerning.
I tested now and at turbo maximum temperature was 61°C at room temperature of 23°C without any cooling just stand up flashlight. Yes it is hot on touch. Before I was tested thermal regulation and its work. With cooling with fan I can reach 1500 lumens from FC40 stable, if I turn off cooling output will go low to 35%
OK, will just buy then and test them (got 2 multimeter with temperature probes). I always tested the max current, and the parasitic drain, and AUX drain, never tested the temp regulation, but maybe I should do it to. With Anduril UI, you just have to calibrate the temperature sensor yourself, and you can set the temp ceiling yourself. But here you just have to trust it.
