I had a MagicShine MJ-808 battery die after about a year. Today, the cheap-o "Cree" generic I just bought crapped out on me without warning after about five uses. I guess I could buy another new battery, but frankly I'm sick of dealing with questionable quality and just want to buy something good and be done with it. Also, after years of going with external battery packs, I'mconvinced that self-contained lights are easier to deal with, especially as I primarily use helmet mounts.
Anyway, what's a good 500+ true lumen self-contained light that retails for less than $200 and is completely reliable? I'm considering one of the Cygolite Expilions (perhaps the 800), is there anything better? Not a fan of the proprietary Cygolite batteries and I would prefer something that uses standard 18650s.
