Groo,

I don't think so, as they rely in electronics, the durabiliti issue is on question (specially for survival issues) as a incandescent will only need a new bulb if something goes wrong, a LED will need a trip to the factory for repair of the electronic board.

That is why in my survival kit I have a E2e with spares bulbs and batteries.

And in the issue of throw, let me show you what the Surefire L-4 Digital Lumamax (which I have) will do at 20 yards in comparison with a Surefire 6 P (both output 65 lumens)

Surefire 6 P (65 lumens retail for $56.00) at 20 yards



Surefire L-4 Digital Lumamax reatil for $160.00 65 lumens at 20 yards



So, they say a picture is worth 1000 words!!
