Emisar D4 Titanium & D4 V2 Titanium Question

Hi everyone

can someone please tell me if the D4 V2 titanium have the same threads as the V1 titanium??

I have 2 Emisar D4 Titanium V1 and I want to buy 2 18350 tubes for them and I want to know if everything is compatible with each other (d4 Titanium v1 and d4 Titanium v2)

thank you

I have a V1 ti and a V2 al. From memory the V1 has V cut threads while the V2 has trapezoidal shaped threads. I don’t know what’s on the V2 ti.

From memory the male end V1 threads fit into the female V2 but not vice versa.

thank you

anyone who owns both can help me with this info?

I have both. Somethings I have tried and I confirm works:

  • v1 tailcap on v2 18650 tube.
  • v1 18650 tube and bezel on v2 head.

I think both v1 and v2 parts are fully interchangeable with the same threads. Can’t fully confirm though since out of town and don’t have both lights with me.

I will wait for you until you comes back home okay please?

Both of your lights are d4 V1 and v2 titanium??


I have 3 titanium d4 v1 but only one of them comes with 18350 tube (it was the last one in stock)

and I want to buy 2 more 18350 titanium tubes for my other d4 Titanium

all I want to know is if the v2 18350 titanium tubes will work with my d4 v1 Titanium head and tailcap

I want to be 100% sure please

anyone else can confirm in the mean time please?

I have both TI versions.

I went and put the V2 18350 body on the V1, with head and tailcap and its the same and works well.

Thank you very much my friend I really appreciated it:)
