[ASK] Tritium vial size for EOSLAMP SP11

I always wanted a flashlight with built in tritium slot, at the affordable price.
One day I saw this EOSLAMP SP11, it has a tritium slot. So I bought it.



The flashlight is currently on the long boat from China, slower than before because it was purchased right before Chinese New Year. Not a problem for me.

While waiting the flashlight, I want to purchase a tritium vial for this flashlight. Too bad, I don't know the exact dimension yet.
Is there anyone here who know the right size of the tritium vial for this flashlight?

I've been searching on forums but none the result.

Thanks for any insights.

Just received and measured the slot, tritium vial of size 6 x 1.5mm fill fits into its slot.

I've got one new pic from the brand VOLLSION !
