Anyone tried that?
I think about buying D4 and swap the leds.

The LH351B maxed out at 4A in my 2016 test, but over 3A there is already little left to gain. So you want about 12A from the battery. Estimating 0.2V voltage loss in the D4 and looking at HKJ’s amp/voltage graph of a high drain cell (30Q), you will have a bit over 12A in the actual build. A bit lower drain cell like the GA will fix that.
This is educated guess of course, in practice it may be a bit different.
They’re cheap… give it a try and tell us :-p
Leds already here, but no flashlight
