By listed dimensions alone, same length as the SC63/SC64, and a little bit fatter, although I don’t know the maximum width of the SC63/64 across the button.
Thanks for the info, but I’m mostly interested in how wide the body section is compared to the SC64. I know this is absurdly picky, but it’s going to decide whether or not it feels comfortable in my pocket :P. I can’t seem to find any information on the body width of the SC64, while TK has nice measurements for the FW3A.
If possible, I’d like the diameter and length of the body of each light. (And how much of a “bump” there is in the FW3A compared to the SC64).
I get where you’re coming from. I’m picky about size of my pocket lights, too
I know somewhere I saw caliper measurements of an SC63/64 by a user on CPF, but I can’t find that again.
My own point of reference is a D4, the tailcap of which is within a mm of the stated size of the head and tailcap of the FW3A. I think it’s just enough smaller to be appreciably less noticeable in the pocket.
Body diameter, across the ribs (widest part of body, not incl. clip): 0.855 in / 21.72 mm
Body diameter, narrowest middle section: 0.820 in / 20.83 mm
Body “diameter” including clip: 1.020 in / 25.91 mm
Head “diameter” at switch: 1.015 in / 25.78 mm
Head diameter not considering switch: 0.970 in / 24.64 mm
Tailcap diameter: 0.950 in / 24.13 mm
Overall length: 3.630 in / 92.20 mm
I did round the thousandths up or down to the nearest 5 thousandths here.
