Been using this light for about a year , got it in December last year and it is still my favorite 18650 light. The configure I had mine is in the Osram W1-6000k Emitters for one channel and the other is Nichia 219B 3500k Emitters. This makes for a nice indoor out door combination with both a more floody high cri warm colour for inspection work and a thrower option for outdoor seeing with the osram. step 3 on the default 7 step of anduril works the best for my needs.
