hey thanks guys for the info, there just isn't much info on it anywhere except that it's got long battery life and has an expected life of 100,000 hours (wow, that equates to 11.5 years continuously!!!)
I have a mag 3w led upgrade in my old 3D and I just bought a 2AA + 3d combo Mag (with the incan bulbs) cheap. So i might try the Nit-Ize as it's pretty cheap from the US (about US$9 from battery junction), keeping in mind that currency conversion and postage to Australia isn't that cheap. Means if I purchased a more powerful Terralux by the time I got it here it would make the original torch reasonably expensive. The Nitize is over AU$30 here. Is there anything else in this low price range? I'm also interested in LED upgrades for the 2AA mini mag and have seen the 1watt Nite-Ize for it...I wonder if it's the same led they put in the C & D mag conversion?
