[ SFT40 is more suitable for multiled flashlights...

I disagree. I think it is a great replacement as a 3volt version of the xhp35 HI.

@Fedtro

it has less than half the lumens, 2000 against the 4800 of the XT60, then surely L21B has a better runtime because it heats much less and because it needs less current, however this is another matter.

this is exactly why I am more intersted in the sft40 in this XT60 (if it were running a 9 or even 10 amp CC driver of course):

more throw, less heat, much better battery life. Also, 4800 lumens doesn't mean much when it will drop to 2000 lumens because of heat and battery life drop over a mere couple of minutes (at most), because the sbt90.2 at 2000 lumens will have much less luminance than the sft40 at 2000 lumens.

Hi, help me understand ... in the link there is the djozz test of the SBT90.2, you can see that at 6A of current it produces about 2500 lumens, to produce an identical result SFT40 has to work at 10A, at its maximum capacity while SBT90.2 works at 33% of its capacity, so with a lower consumption and heat production I suppose. Then I wanted to ask you another thing explain to me why 2000 lumens are different in two different torches, if something produces 2000 lumens regardless of how it got to that performance, 2000 lumens are always 2000 lumens as 10 kg are always 10 kg. Please help me to understand better why I do not contest your statements, only as a neophyte hungry for knowledge I would like an exhaustive explanation. Thank you.
