Well, not that high powered. It’s an array of 10mm LEDs, which have the same junctions in them as 5mm LEDs, but a bigger lens (and usually a tighter beam).
This array is cheap and doesn’t need special cooling, but it’s good for only about one watt of output. That means that, with modern LEDs, it probably appears significantly brighter than a two-watt incandescent bulb, at the price of no longer having an adjustable beam.
Many LED flashlight makers have come up with retrofits and/or hacks of the big Mag-Lites. The biggest one I’ve ever checked out was the Elektro Lumens Tesla-6: http://www.dansdata.com/tesla6.htm
(21.6 rated watts!)
