66! Bought to use with the spare Astrolux S1 & S41 tubes & and head from an S1, which all fit together nicely. Now I just need to decide whether to go 18650 or 18350.

Tail cap I bought for my Astrolux S42. I do not need to switch off the light by the electronic switch. Good promotional price, fast delivery.

Some time ago I push my Astrolux S42 to the limits and let the temperature raise to 100°C. And then... I cannot turn it off because my finger instantly got hot. I have a plan to mount this S41 tail cap to S42 as a safety switch because of S42 is a much more powerful flashlight.
