It’s great to see the max output from the FW21 Pro. Too bad it steps down so quickly, as does the FW3A. These “pocket rockets” aren’t really meant for sustained turbo use. But for momentary use it’s impressive.
Yeah, not meant for sustained Turbo mode use…but just like having a car fitted with Nitrous oxide, more used on occasional burst of extreme power output. It’s better to have it and not need it, than need it and not have it though.
I have lost count of the lights I presently own, and most of them are the present “hand-burners” when used in Turbo mode, but what I know is I have only one light (among the other one or two ever sold, IIRC) that can sustain its Turbo mode as long as the batteries sustain the load without throttling down to High, and that’s my Fenix TK70.
Edit: I think the other light I once owned that does not step-down from Turbo was the Acebeam K60, IIRC.
