  1. Seems like a nice product.

    Is there the equivalent of a trigger on the grip that you squeeze to activate the light?

    • It’s a pressure switch in that front finger cut-out. You can see it if you scroll the images on their website.

      They refer to it as “auto on when gripped” in their “activation” portion of their “Details” section.

  2. 90 minute runtime on $12 worth of throwaway CR2s and no strobe mode…. I’ll wait for someone to come out with a rechargeable copy for a little more.

    • I think you can run rechargable batteries made for Streamlights in most things that take CR123s. Just a thought.

    • That’s a LOT of runtime as there no constant-on mode. Press and it’s on, let go and it’s off. Oh, and Olight is made in China. The Viridian is made in the US.

        • I’ll elaborate:
          “Made in the USA” or “Product of the USA” really is only required to be about 1/3rd made here and doesn’t mean anything anymore.
          “Built in the USA” usually means with parts from other places like China or Taiwan.

          So is it that much better? That’ll be an individual decision

      • Designed in the USA, yes. Built (assembled) in the USA, yes. But built from components made in China and Japan (and sometimes Germany).

        According to the Federal Trade Commission, “Made in USA” means that “all or virtually all” the product has been made in America. That is, all significant parts, processing and labor. that go into the product must be of U.S. origin.

        the loophole: Parts/material made in other countries that are imported then sourced from an American company are considered “U.S. origin”. Thus a product built (e.g. assembled) in the USA can claim ‘Made in USA’ for their products when in reality the whole thing may physically (in terms of parts and materials) be actually of foreign ‘origination’.

        “made in the USA” just means the final product is constructed in the United States, not that it was actually completely made in the USA. Its ‘legal truth’ vs ‘factual truth’

        There are no firearms optics/lasers/lights today that are factually truly “made in the USA”. All of them marketed as “made in the USA” use parts/materials that originated in foreign countries and are simply ‘assembled’ (referred to as ‘built’) in the USA. Its simply too expensive to manufacture all the parts needed for firearms optics and lasers in the USA, if that were to happen firearms optics/lasers would be cost a lot more than they do now in the U.S.

    • Not sure exactly how it works. If nothing more than gently holding/squeezing that grip turns the light on, I don’t want it. If you have to squeeze firmly and intentionally to turn it on, then I am interested.

      • IMHO, switches for things like this should be placed where the chances of accidental engagement of the light is minimized.

        Turning on the light should always be an active choice made by the person holding the gun and therefore require a specific movement towards that goal. Anything that increases the chances of accidental or negligent “discharge” of a “tactical” light should be eschewed.

        I’m not as far down the road as the folks who’ve gone against pressure pads on a top rail, but I absolutely understand why they have chosen to delete that feature from their own guns. Seeing your buddies get killed by a piece of gear or a specific setup tends to have that effect.

      • My understanding is this from Viridian: There is a ‘nub’ in the front portion where the finger goes. It that ‘nub’ is ‘gripped’ with the finger the light is activated, and when that finger pressure is released the light goes off. So its not a constant on simply because you ‘grip’ with the rest of your hand on the rear portion and it is user controlled on of off. Viridian calls this ‘Grip ‘N Rip: LED grip activation putting shooters in control for an unmatched tactical advantage’

    • Crimson has the Rapid Illumination Grip. Its switch is a separate corded switch if i remember correctly.
