PJS,
Off topic for a minute -
Cant help thinking that it might be a great candidate for the 3C mod, along with one of jbecto's 4-LED PR units. Try Lambda's Krylon technique to texturize the M*g reflector (maybe go heavy on the texturing), and then it ought to be something like a TurtleliteII x 2, with a really long runtime. I haven't tried this particular combo though, as I've only just gotten the hang of the texturizing process in the past couple of days, and I don't have one of JB's LEDs.
Just a little food for thought...Thanks for lettin' me stray off topic for a moment.
John
