I have been an eagletac guy in the past but bought this EC20 probably about 18 months ago. It was a killer light for 39.00 dollars until it quit tonigh . Battery has good voltage, and the button appears to be working. Don't know what happened. Any way I would like to hear about any new lights that are out that I should look at. Must be 18650 and I like a beam that leans to the floody side. I will research any lights that are suggested. Would prefer to keep it in the fifty dollar range, but could go higher if needed. I gig for flounder at night alone so dependability is needed. Luckily the nite core died tonight in my front yard.
