I ordered the Thrunite T1 yesterday. 1500 lumen from such a small light was just too inviting. More of a novelty but oh well. I carry a Folmov 18650S with a 3000K XP-L Hi emitter. One of my favorite EDC lights. its about the size of a 21700 battery. S1 is a great budget light also. I have 4 or 5 of those in different colors. Lots of great choices. Good luck.
