Good info. I just ordered a few of these and I’m sure I will do this mod.
These drivers with the stepped modes look like constant current linear mode FET drivers like led4power’s. Is the other ‘ramping’ driver from convoy mentioned above also this type of driver? The description and UI seem strange. Is the current limited to 8A?
Thanks for the reply, Guess what? I have bought the 1210 sizes and its on its way! Haha, I read it off other threads of the similar driver but in a 17mm size I think?
Since 2010 size is 5mm x 2.5mm and 1210 is 3.5mm x 2.5mm, I suppose this allows me to join two resistors serially to lower the output (which was my main objective anyway).
I actually do see another R010 on the board, at the left side of the 10pin IC. Could that be the sense resistor as well? Regs
Strange though, when looking into the datasheet of the MOSFET, it seems like the big R010 resistor is connected to the Source terminal of the MOSFET (the first 3 pins of the MOSFET are tied together). The Gate pin on the other hand is not connected to the R010, it goes under the MOSFET (or under) to another location. We can see that all the remaining pins on the right side of the MOSFET (4 pins) are connected together as the Drain terminal, which means the datasheet is correct to the MOSFET used here.
I m not good at electronics. Does the Gate terminal connect to the “sense resistor” to bias the Vgs?
Can step down be eliminated from a Sofirn C8F, 18650 version? I know it is a long shot asking but WTH. The three minute timer really isn’t needed. Not on high anyway. Maybe turbo.
Over my head. I was hoping an EE could show me which component to remove or change. I did discover that in group three it steps down to about 1000 lumens so that is not so bad. Still, really not a lot of heat buildup, even at 1500 and 2500. One of the main selling points of a floody C8 in my estimation.
