I got the Terralux MiniStar 2 which is a 1 watt led for the mini-mag, and it works great.
In fact, I was working with another engineer who had a std maglight, and we were troubleshooting a contol panel. I almost felt like I had to apologize for having such a brighter whiter minimag light.
Actually I'm not sure I'd want a 3 watt for using indoors, if you use it for close up work, (like inside a control panel) The 1 watt can almost be blinding, and ruin you vision for efverything outside the beam.
Also, I get at least 3 good hours out of 2000 NiHH batteries.
And so far, I have been left in the dark for more that 2 hours a day /ubbthreads/images/graemlins/smile.gif
