Uhh, yeah, we know about the LUX-RC tech. A LED is a diode and it can "read" light as well as output it. Some ATTiny85 drivers even wired in the input on pin #7 but never ended up using it. A design EE I worked with suggested it and I told TK and she dabbled with it for a while, but not sure how much success, but then at the time, there wasn't much code space available in the 85 MCU. Pretty cool because no additional sensors are needed.
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.
