Streamlight has a very annoying habit of going to extremes.... Extremes as in, their designs are either really great or really crappy.
I'm not talking about workmanship, fit & finish, or quality. Just designs.
Winners include: Stinger, TL-2, Strion, and TLR-2. (Surefire had to scramble to come up with something that could compete with that one).
And then you have the designs that make you wonder if someone was smoking something a wee bit stronger than tobacco, when they came up with the design ideas.... Like the NF-2 models. My xenon-bulbed version was a light I really wanted to like. But Grip-ring + flush tailcap switch =
Nevermind that the grip-ring itself was poorly designed. (There are other misses, but the NF-2 is by far the worst).
And now we have the Super Tac.... An answer to a question that no one asked. Head is about the size of a Surefire M6. You can forget about M6 performance from a 2-cell light. Huge reflectors + 2xCR123 can = Great throw. But then again, there are other LED-based lights that take 2 cells, have excellent throw, and smaller reflectors. I can easily put my Tiablo A9S into the back pocket of my pants. Super Tac?.... Not so much.
I like Streamlight. Always have. But no other company has so many lights that are either hit, or miss. Nothing that can be considered
somewhat good. It just gets frustrating sometimes.
Honestly, if Streamlight put in more money and effort into R&D, they could compete with Surefire on an even basis. After all, with Streamlight, it's not as though the quality isn't there.
