My quest for improving the MiniMag is what landed me here originally.
At the time, I had one in every vehicle, desk, boat, tacklebox, toolbag, kitchen, etc.
Here's the bottom line : The LED modification described in a new language above is one of the best. It's also kind of spendy. If you want sheer brightness with no consideration given to runtime, order the TL-3 hotwire kit found in that link above.
If you'd rather have a great light about the same size, with a manufacturer's warranty because you're not changing anything, I am suggesting the Streamlight TL-3 incandescent.
Straight outta the box, you have great throw, focus-ability, compact size. Amazon had the lowest price on the day that I bought a couple. Sometimes they are for sale here, used. Great stocking stuffer for the non-technical people on your list.
