Wellp, some UF lights make fine hosts (eg, C8, ’502, etc.), but only if “real” UF (used to be, the Great Copier UF became the most copied, too).
Doesn’t matter if you have a DD light that can belch out 2000lm ’til the LED turns blue, it’ll heat up like the business end of a curling iron in no time, and be rather uncomfortable to hold without oven-mitts.
So, you can make virtually anything a “pocket rocket”, but it doesn’t mean it’s a Good Idea.
That said, if the light has a good thermal path, sure, you can fit it with an XHPwhatever and DD/FET driver and let it cook… for a short time. Hence the oft-lamented characteristics of stock lights with timed turn-down, to keep the light from self-immolating.
Still, if you want a wow-factor, to be able to light up an entire valley for a short time, there’s no reason not to. Intense pain and the smell of frying bacon will let you know when it’s time to flick it off turbo.
