In the past I used Easton Tracers but it looks like they have discontinued them. I never had issues with them so surprised me. I bought some Lumenok's and like the brightness but for some reason they are finicky to trun off reliably. Wiggled one to get it turned off as instructed an put it in the box. When I opened it the next day it was on, so no clue how many hours wasted on the battery. Some of them will go out, but then come back on dimmly lit. Have a bunch of firenocks that I bought and never used but they're too small even if I could get fresh batteries. See a lot of no name China ones on Amazon but don't want to waste time and money trying them, without reccomendations anyway.
