I've been trying to get as much information about Pila as I can but there doesn't seem to be much. There are a few threads on here and a couple reviews out there and that's about it. There aren't even a lot of places that sell them. Is this just a company that is not established yet or is something wrong with these lights? I'm interested in the GL4 specifically but that seems to be the model with the least information. Do these lights have quality problems, are they worth looking into as a tactical light? How do they compare to Wolf-Eyes M90X? I do have all of the vital statistics, I am just looking for some real-world experiences.
