    This cannot be correct.
    Please provide o-ring size for d26 1600.

    So if I got this right it's:

    * Old D26: 28x2.0mm
    * D26 1600: 33x2.0mm

    ?

    That's what they say, but it is not correct. I have the new D26 1600 and measured both the existing o-ring and the o-ring groove itself. 33 is too big for sn ID. OD maybe, but an ID.

    I measured this at an O-ring store yesterday.

    For the old D26 (1100 lum) it's 26x2mm and nothing else.

    My D26 1600 measures at 28x2. Hard to believe they are different!

    Your discussion is very interesting. I don't know if you are measuring the inner diameter or the outer diameter. In fact, both 28mm and 33mm can be used because they are flexible:)

    Always inner diameter.

    The D26 (old, 11 lumen) comes shipped with 26x2mm at least. That's what I replaced it with as well.
