Aggressive knurling

This thread has just prompted me to realise that I can use an S41S 18650 tube on a BLF A6. Thanks, guys - I really like grippy knurling, and the S41S version is the best I’ve seen.

Heading over to Banggood now for a couple more S41S 18650 tubes

Phlogiston, have you actually tried an S41/S42S tube on a BLF A6?

Yes, I have, and it did work. More details on your other thread:

BLF A6 / Astrolux S1 tube threads lego?

I have two BLF A6 and two Astrolux S41S, all from the first batch of each design. The tubes on mine do lego and work. I have heard that Astrolux is very bad at making identical parts in successive batches, though. I’ve ordered two S41S tubes for my A6 lights, in spite of the risk that they might not be compatible between batches, so I’ll see what happens when I get them…
