The Mk IV ZL’s already have a “programmable” UI. E-stwich UI’s, eg. Anduril won’t run on a mechanical switch light like the S2+. Flashing or modding ZL’s is nearly impossible due to their unibody, press fit bezel, potted electronics one piece driver - led board. Correct me if I’m wrong. However thare are a few people here who actually managed mod them. [MOD] Zebralight SC64c emitter swaps
Zebralight is a very proud and stubborn producer. From my point of view they refuse to listen to the helpful suggestions and demands of the flashlight community. They made a series of really stupid mistakes in their new lights which could have been easily avoided. A collaboration between ZL and Toykeeper would result in near perfect lights but I don’t think it is going to happen anywhere soon if ZL sees their own UI as perfect, while it’s not.
