Have to see what the ripe chilli colour is I think, light green could mature to any colour.
I've got even got a red hab* that is that light green colour before ripening.
*I don't know what my chili plant is though either.
Thank you every one for responding, except you Al I am thinking sweet venetian habanero but will find out soon enough( when i eat it) and let you know!
My leaves started wrinkling like those in the pic. A search returned suggestions of a Magnesium and or Calcium deficiency. I applied a foliar spray of Cal/Mag and the leaves flattened out with-in a couple of days.
