    Rich, which one is the LumitopVn? Are you referring to the EDC18?

    Ooops, I left that part out. FW3Avn.
    For less performance, use smaller flashlights; and for most performance, use largest flashlights.

    I won't be a lot of help because my D4's are quad 351 and XPL's.

    I know that Vinh favors just about any version of the D4vnV2, unless someone specifically needs a tail switch. He has stated that he likes the FW3Tvn but isn't as big of a fan of the FW3Avn because he says for him, it's just too light, heats up more quickly and doesn't feel as solid. It's great however, if someone really wants a lightweight 18650 that can do 3750L and 44Kcd, while understanding its limited thermal capabilities.

    The FW3 has a smaller aperture, so in order to fit the quad optic in the head it has to be shaved/trimmed down in diameter. This causes the some mild, asymmetric petal-ing on the edges of the hotspot, mainly seen when wall hunting, which I don't see with the D4. Since the LED's are closer to the edges of bezel in the FW3vn, it probably doesn't get lumens OTF as efficiently as the D4vnV2. I'm guessing that there's probably less resistance in the D4's switch as well. I prefer to carry the FW3 because of the tail switch and solid clip but when it comes to beam quality and maximum performance the D4vnV2 is probably better.

    Thank you, Patriot. Your detailed and valuable observations are just what I am looking for. Better heat management versus lower weight. More solid feel versus less weight for mouth hold. Smaller diameter versus better beam performance/better beam profile.

    Side switch: My fingers land near it, quick rotation in fingers to find it.

    Tail switch: I know exactly where it is, but my fingertips land far away from it, and more manipulation needed to get my fingertip on the switch. But, tail switch is better for mouth hold smaller lights.

    I am continuing to round out the small light department of my collection. Today, a few months late to the party, arrived the D4V2vn with throw optics and 4x White 2 emitters, 4020 lumens and 429 meters throw.

    The first thing is the amazing throw. I tried to visualize the throw from seeing the spec, but I had to see it to be amazed. This light is the throwiest of the seven lights that I am comparing it with. 4,020 lumens and a nice, well tempered beam profile yielding 429 meters throw in a single 18650 compact light is just an amazing sight to behold.

    It does get hot in turbo fast, as known and expected.

    Size: A little bit more head diameter than the S2 Baton, and significantly shorter than the E4K.

    An amazing beam profile/beam performance from this size classification!

    Left to right, if the pic attaches correct pois: P60vn Cryos 4 x XP-L, MMU-X3vn 3 x XHP 50.2, TM9Kvn 9 x XP-L, NSX53vn 3 x XHP50.2, E4Kvn 4 x XP-L, D4V2vn 4 x W2, S2 Baton. stock.Attachment 11850

    Rich, all of those lights are quite cool! It really puts it in perspective to think that short, little D4vn has more throw than all of the others. I like that you mentioned how short it is, yet it doesn't have a really tiny head. It actually turns out being nearly perfect size for that optic and the performance speaks for itself. It makes me happy that you're so pleased with it!

    Any beam shots please?

    Hello Patriot, Thank you for you kind reply!

    Hello daffy, I do not have the photography equipment nor the skills for decent beamshots; I have tried, and they come out badly.

    For me, better is to describe new light "A" beam profile/beam performance compared to older, recognized light "B".
