Because the 18650 battery won't fit inside the opemning in the head so a special two stage semi self contained arrangement had to be designed. The 18650 tube isn't actually an open ended tube, it has its own screw on end that then screws into the head of the torch.
I'm glad you explained that. I was thinking of how to explain it without a picture and I couldn't come up with anything concise. :thinking:
