Put a MJ LED from Lambda in the minimag, 35 hours of run time on 2AA lithiums. If your Mag is a 2D, either put a brighter bulb in it or a drop-in Luxeon for more even runtime and better color.
I will go camping in a month and plan on bringing my family. My sons will have Peak AA 5 LED and Arc AA on them clipped to their belt loops. My wife will use an Elektrolumens 2D bent head light with Luxeon for 24 hours of run time.
Myself, a minimag BB500 R2H, peak AAA 3-LED, 2D Mag with an R2H Luxeon mod running at 3 watts for throw...and a 8AA to 2D adapted Mag with variable output pushing a Luxeon V (nFlex pushing WX1S)
I have found that it is great to have a light with throw to see what is walking around. It is great to have a light that runs at least 5 hours with a lot of flood for the campsite. My modded 2D Mags will provide both of those requirements, head on for throw and head off for a huge flood of pure white light. My 2D R2H Mag mod runs 8 hours on a set of 11,000 mAH rechagable D cells. /ubbthreads/images/graemlins/happy14.gif
Ian, if you are taking any kids, grab those Nuwai 0.5 watt single cell or two cells lights. They are durable and quite bright with a long run time. If they are smaller children, the Dorcy AAA is a great light for their small hands.
