The D4S is much larger in the photo, but the shadows on the sides of the FW3A give a false illusion of being even slimmer.
Copy the photo, reduce the contrast, increase the exposure illumination and see the difference.

Yep, that picture certainly does make the D4 look huge.
EDIT: It is huge compared to the FW3A after all. The picture is of a D4S…. a 26650 light. See POSTBELOW by iamlucky13 for explanation.
Except for length the FW3A is closest to the size Convoy S2+ no doubt.
And without the bezel & head of the D4 it probably would be closest.
That picture is a huge optical illusion.

Is it only coming with the frosted optics? I remember seeing a few posts about Carclo options for this so I may just order a different for it at some point.
I believe so. If I remember correctly, the normal un-polished version produces an ugly beam but is throwier. A frosted one looks nicer and can be polished to give a bit more throw while still maintaining a pretty beam.
I have so many triples without frosted optics. Is there something about this flashlight that distorts the beam that much more than a D4, Oveready Boss, my modded triple Eagletac D25C, or other random triple mods?
I would assume some rubbing compound, like for automotive paint/plastics, and a rag would be sufficient to make the optics clear. Even tooth paste might work.
Is the frosting on the lens so deep that you actually need to sand it with sandpaper? That’s more extreme than what I was thinking.

If I recall correctly, it’s primarily a matter of polishing, not sanding. It may be sufficient to rub it against denim or newspaper or something along those lines.

Toothpaste or a paste of baking soda and water are both common recommendations for removing the haze on automobile headlight lenses that develops over the course of multiple years of sunlight aging and/or driving through the gritty spray kicked up by other cars when it is raining out. I suspect they would also work for Carclo optics.
Last time I polished one of these optics (which was several years ago), I mounted a triple star onto a bit and then put the bit in a hand drill. I then put the drill pointing upwards in a wood vise.
I then placed the optic into the star. To polish I used one hand to hold the drill button down and the other to place the cloth against the optic.
For the actual polishing I used jewelers rouge on terrycloth.
I would like to make sure I’m down for 2 lights, one of each. I’m currently on the list at 737.
Thanks
How odd, you used to be at #497 and #732. Now I only see the single listing at #737.
The main thing is that you said in the thread that you want 2 units. The list is created based on this thread. So don’t worry about it. Once the list is updated you should see your name on there twice.

Looks great!

Is there a video on how to polish a frosted optic?
The link in Joe’s post seems to suggest you can just rub it

I know I’ll find a way to mess it up w/o visual instructions. LOL.. I am special.
Pro tip: Buy spare optics

^ Those dimensions are for the D4 (18650 powered). The picture shows the larger D4S (26650 powered).
For a comparison with the D4, see the photos of the 2nd prototype on page 1 of this discussion.
I do not have any of the D4’s, so nice to know the picture was not that much of an optical illusion after all.

Commodity LED optics being relatively inexpensive, this is wise.
That’s a very nice, elegant light!

With 1000 to 7000 grit Wet-Dry paper… you are not removing much. Mainly polishing once you get to about 3000 – 4000.

Please put me down for one more. This will be for a total of 3.
Thanks!

Please put me in for one in XPL HI
Thanks!
Add me too. Xpl hi cw
Please put me on the list for one with LH351D. Thanks!
Will this light be mod friendly?

Only in the sense of changing leds, optics and maybe reflashing a new UI. The driver will be unique and not easy to replace.
