I saw a dealer catalog about a month ago and noticed that Pentagon Lights is coming out with some larger lights to compete with SF M3s, M4s, and the like. I didn't see much detail, and have no clue when they'll get released, but it seems to be coming. To me, it seems PentagonLight is the only US brand targeting SF as a direct competitor. SL, Pelican, and Inova all have their own niches and don't offer that many products that compete directly with SF's offerings. For those needing SFs for specific uses and needs, PLs may offer a better priced option. Wolf-Eyes is the only other brand I see as a competitor to SF, but they're not marketed as widely in the US as PL.
