Nope, again, but that one is closer. I will give more description below, but I don't think it is on the Web. If there is a BJ's where you are, you could go and look at them. Otherwise, we're probably going to go around in circles to no useful end. It may not be the absolute best hand-light available, but I like it, and prefer it to the Maglight.
Actually, the tasco label on the light is in exactly the same font as the optics company's at
this site. The distinctive T and unique A are the same. So either the optics company makes the light, or somebody in Taiwan is disrespecting their trademark.
===============================================
The one I'm on about is not so shiny a silver as the one in your link. It's not actually a matte finish, but it's not bright, either. The body of the light between the head and end-cap is a straight tube, with checkered knurling in its middle section. The "tasco" label (lowercase) is in the knurled area.
The end-cap is also evenly tubular, with straight knurling in two rows. There is a black plastic button that fills a hole at the back end of the end-cap and serves as a mount for the wire lanyard-ring. (There is no lanyard supplied.) The button is sealed against the inside of the end-cap by a thin O-ring. O-rings also seal the end-cap and head on the body.
The head is a larger diameter than the body, like a Maglight, but has a peaked boss around it. A series of V-bottom grooves are cut into this boss to a constant depth. Because the boss's diameter is larger at its middle and tapers away at front and back, the grooves have an elongated diamond aspect.
The machining on these lights is first-rate - at least as good as Maglight's.
