That’s a pretty exhaustive review, with teardown, very nice.
We can’t see the markings one the boost controller, but this looks like a LTC3787, a dual phase synchronous boost controller, I planned to use that one on a high power driver as well. Indeed it looks very well designed, the copper parts transferring the heat from the FETs to the body are a very good addition.
This isn’t necessarily true, the LTC3787 can limit the inductor current, effectively decreasing the output current as the input voltage decreases, or the output current could be limited depending on Vin by the MCU, the Acebeam E70 driver for example opt for for the later solution.
Considering the very high battery current needed at low Vin it would make sense that a limitation is in place, to check this measure the max output with a low battery (unless I missed it in your review).
I am sure you are correct in all the technical details you are explaining. I am not an electronics expert and as you know I usually turn to people of knowledge in electronics such as yourself. What I meant to say in the review is that the driver will keep the output stable for as long as the battery can provide the necessary power and then move down to the next lower level, keep that stable etc. The only other thing that affects output, is of course thermal control.
Yeah my comment was only regarding the max mode (I should have made that clearer), indeed you’re right for any of the other mode the output won’t change with battery voltage.
Great review! I am going to have to get one of these, although I think the 5000k 70.2s will be the way I go.
Great job what an awesome review… I was wondering if you were able to remove the bezel I have quite a bit of moisture behind the lens and I would like to rid the light of this pesky moisture. Been blasting turbo for some time but to my dismay moisture level remains the same😩
Thank you.
I have not tried to remove the bezel but I would be surprised if it is not glued.
