Don’t say that yet. I could have sworn it said Fandyfire on the other side of the light but will have to wait until I get back home to confirm. It is more likely that the “Warrior” monicker is on both brands and “YL-U2” is merely the model number used by FF.
Got the FandyFire version earlier today, comparing to the SRK, as mentioned already it has more focused beam and not as floody. Still a floody light just not as much as the SRK. A lot smaller than the king in circumference, head and body. Excellent threads and build quality. Do I like it better than the king, no better or worse, like them both. This light is a lot easier to pocket than the king. The king has a stainless bezel this light doesn’t have.
