Umm, that is the hobby. There are hundreds of high end, super bright, LED flashlights out that that make Maglights look like birthday candles. I have a single AA Cree XM-L LED light that is brighter than a 6-D cell Xenon Maglight! I have a single AAA light that is brighter than a 4-D cell Maglight. In the past few years the circuitry and LED technology has advanced rapidly. I have lights that will light up most of a large field. Another light that will shine its beam over 350 yards. I have a limit as to how much I will spend, but there are people on those forums who have hundreds of lights. I have about 18, and many are small lights that cost $15-$35. But I also have several that are just over $100 and one that cost $215. But there are custom lights that cost over $1000. I wont go that far. Its no different than here, where people make a hobby out of it, and some people collect many different models. I am done buying any for a while as I have all the types and sizes of lights that I wanted(although I keep seeing other lights that I'd love to have!)
There is a whole forum, well actually there are several forums dedicated to lights, but the biggest one, candlepowerforums is HUGE. At any time they've got 800-1500 people logged in. Some times well over 2000.
