$37 is a great deal for the brass pineapple. It’s basically the same as the Ti Lan but with a brass host. It is very heavy solid brass. However I do like the looks of the Ti Lan more. I tempted to buy backups because they are so nice. Have anyone modded them with different driver or emitter?
Maybe it means the Titanium is so shiny that is serves as a second light source by reflecting light. I have both the TiLan and Pineapple and there definitely is only one 219c emitter.
I would be surprised if those Trits or so called “trit vials” were included in the sales price. If I understand the price @ Banggood correctly, it is $ 7,69 for one (!) trit vial. Looking onto the Reylight Titanium LAN I guess you need 4 trit vials for the head and 7 trit vials for the tail cap to have full fitting. So, that adds up to $ 84,59 on top of the price for the flashlight.
Personally, I am happy that the flashlight will come “naked” without these trits for Tritium is known to be a radioactive gas, emitting beta radiation. I would rather put some phosphorescent epoxy onto my flashlights than any radiating material, even if they tell you with tongues of angels how harmless it seems to be.
