Show him something like a Fenix E20. It will be at least ten times brighter, use the same batteries, and have the same focusing ability as his minimag. You need to show him that other lights can do the same things as his favorite light but do them way better. I got my cousin to edc an E01 after showing him how it would blow away his Mag solitaire. (Obviously, I had to buy it for him, but it was well worth it.) I don't think he'll ever go back to that lousy Mag. Don't start someone off with a light that uses expensive lithium batteries. Contrary to popular belief here, not everyone has Internet access and can get them cheap. A friend was trying to show off a $60 Pelican light that another friend gave him on a campout. He wasn't happy when I told him how much the 123A batteries were in the stores. Lithiums and lithium ions also require special care and disposal. Start him off with a light that can take alkaline, NiMH, and lithium batteries like an E20, L2D, E01, or other similar light. If you don't, he'll either never use the light or he'll come running to you every time he needs more batteries. By the way, even a $12.50 E01 has about the same brightness as a standard Minimag. It's not that expensive to get him something better than he currently has.
