...Seems I remember reading the output of the PR based SMJLED is about .5w but I don't know...
Trust me, the outputs do NOT compare. The SMJLED's are much, much brighter than any of the 0.5W lights out there. I know as I have a bunch of both.
The SMJLEDs draw about 0.35 W of power but they have some internal magic which manages to squeeze about 3x the efficiency of any other LED light out of that input. Their output is pretty much the same as a typical 1W LED (is very close to my Fenix L1Ps when both have fresh cells), despite drawing 1/3 the power.
They also have good color and put out a good beam pattern in the "United Outdoors" model 2AA cheapo light IF you get the version which has a faceted reflector. If I had a Walmart with 25 of those lights (with faceted reflector) in stock near me, I'd go out and buy them ALL for SMJLEDs or mods or both. I'd probably even get a bunch of the smooth reflectored version, seeing how things are right now.
You might not be that crazy but you might consider getting a few more and putting them aside. I don't think you'll regret it.
