The bright flares being discussed put out light in all directions like
a lantern.
I don't have anything that bright, especially in a lantern.
However, in the automotive section of Walmart is a new portable HID
light that would fit in a cave pack.
I haven't paid any attention to HID lights, because they don't seem practical
for caving. They are spot-lights, they are very expensive, the batteries
only last less than an hour, and they are heavy. I presume the
filament is fragile if you
drop it.
However, it would be handy to have one in the car on an off-road trip.
In Bustamante Canyon,
you could shine it up at the entrance of Precipicio at night, but I
can't think of a reason why
you would want to do that.
However, the HID technology is advancing and more HID products are on
the market now.
Here is one for $ 1,800 not including taxes:

I presume cave divers prefer HID flashlights to LED's, but that should change as
LED's become brighter, more efficient and less expensive. I don't
see that happening
with HIDs.
