Left to right: Zebralight SC600w III HI, Convoy S2+ 18350, Sunwayman V11R, Shortened Convoy S2+ with 18350 tube
One option for those who don’t want to shorten the head of the light: If you shorten the pill only, you can use the stock head and 18350 tube with an 18500 cell and the metal clicky. This would give you a light more compact than my metal clicky 18650, while still having a lot more power than an 18350.
With the tailcap clicky, the shortened S2+ isn’t really my most compact Convoy. That honor belongs to my old Convoy S2+ sideswitch mod
The S2+ with sideswitch is shorter than a Zebralight SC52, but uses an 18500 cell. However, the sideswitch mod left a lot to be desired. My efforts to paint it to match the anodizing look lousy, and I doubt it’s as durable or waterproof as the metal tailcap clicky. If I were doing that mod again I might just leave it bare aluminum.
