This is just a thought but for all of you in Europe that can't visit the local 'Radio Shack' (however much we'd like to!) I have been experimenting with different bulbs in my 3D Mag to get a brighter beam using common bulbs available over this part of the world.
Basically I've simply been overpowering the bulb using bulbs designed for 2D flashlights.
The first bulb a tried (I can't remember what it was called) blew immediately.
Not to be disheartened I tried some Philips 2D cell batteries and they lasted for a while (20 minutes, very bright!)
At the moment I have an Energizer KPR 102 bulb also designed for 2D cells and it's still going strong although I guess it will go the same way as the others soon.
I'm not sure how wise this is, I'm not a technical buff.
The Energizer and Philips bulbs are relatively cheap,20 Kroner for two compared to 70 kroner for the standard 3D Mag bulb so even if it doesn't work out you'll not be feeling to bad about your little misadventure.
As for the difference in brightness, it is noticeable to say the least and much whiter.
If you want to see your 3D Mag working a little harder and marvel at it's new found brightness, by all means try it, if you're going on a dubious mountain hike or leaving your Mag at hand for an emergency DON'T.
This is not a serious alternative, it seems Carly or the XPR103 would make a more sensible decision, but then this is a man that goes to the supermarket to buy food with the meagre pittance I have left and come home sporting a new flashlight!
Try explaining how this could have happened to your girlfriend!
