We heard back from our Fenix contact. Here is his response:
"I let the engineer look through the comments and he thinks that it's common that people would focus on the numbers, but usually they don't realize the balance and control between the high output and the heat generated. So you may reply according to the following points:
1. The TK35UE V2.0 has a built-in heat control chip, so the brightness will be controlled to step down when the temperature reaches up to a certain level. There is a note under every specs chart, and all data are tested under laboratory circumstances. However, if it's under certain conditions, like low temperature or good heat dissipation environment, the Turbo mode will perform better.
2. The new version can reach higher output and at the same time the runtime doesn't reduce at the same brightness level comparing to the 2018 version. What's more, the new version is smaller and lighter."
