Summary

The Wurkkos FC11C is a nice upgrade of the FC11: The light quality has been further improved by using a Nichia 519A and the buck driver keeps the brightness constant for most of the runtime. Combined with the easy UI and the integrated charging function, the FC11C is a really great flashlight for everyday use.

I can’t really think of any negative aspects. Perhaps it could be a bit shorter. Basically, Wurkkos has done everything right. While I have often recommended the FC11 as an entry-level flashlight, the FC11C will take its place in the future.
