Hmm that’s annoying! I wanted to swap the heads but the newer light came with square threads and the other one I have on order is probably the same. Oh well, more incentive to build a new one xD
Maybe you can ask Simon if he still has them. There are different stores selling S2+ lights, but I’d guess it would be a lottery trying to find a specific one. So, maybe the source is the best solution
The older S2 has a slightly longer head, has a long reflector and a short pill (left)
The newer S2+ (that we know now), has a short reflector and a longer pill (right)
The left combo fits the S2+, but the right combo does not fit the S2.
The inside thread in the S2 head does not go “down” as far as the S2+ thread.
After seeing your picture I started to wonder, if you could built S2+ with S2 pill and S2+ reflector. Then it might be possibe to use 18500 tube with 18650 battery. Kind of full size shorty S2+.
Well, maybe I someday try to build 18650 using S2+ with Jaxman 18500 tube and S2 pill. Kaidomain has those pills separately for sale if I remember correctly.
Nope, you can’t!
The logic is precisely inverse to what you say! If you use the S2 reflector/pill in a S2+ (which is already shorter than the S2) you will eventually reduce the space you already have for the 18650 battery with and 18650 tube.
The mod you can do to have that configuration is to turn the S2+ into a triple, by using the S2 pill in a S2+ .
I’ve done that mod inspired in some other people’s mod, too.
