My Thrunite TN-12 (2014) has developed a flicker/short. So I need a light to replace it. I don't want a Nitecore. I have read to many bad reviews about them. I looked at the Fenix PD35 but this Eagletac is over a half inch shorter at 4.8 inches and an ounce lighter at just 2oz. 1200 lumens on high with 4 lumen low output. I have heard a lot of good things about Eagletac batteries just not much about their lights. Maybe that is answering my question as to weather or not their good.
