It is only Flashlight Tube. the package is without any battery. and it is only used for Manker E14. Because some guy would have not 18350 battery at home.and most guys like 18650 battery. If you buy high capacity 18650 battery to run Manker E14, the runtime should be longer than 18350. so Manker have produce one 18650 Tube for Manker E14.

It's a simple adapter tube to allow the light to use the larger 18650 batteries. Everything works as it should. Personally I feel the tube should be included with the light.

You're crazy if you don't add this to your E14 order! Fit and finish are perfect. Just make sure you orient it correctly (shorter-threaded end towards the head), although if you put it in backwards, it won't hurt anything. Gives you the ability to run 18650's if you don't care about the added length/weight. I was able to fit both unprotected AW IMR and Efest purple IMR, as well as a protected Orbtronic, and everything worked flawlessly. An LG MJ1 with PCB was too fat. Man, am I happy with this (and E14) order!
