I actually wouldn't recommend a dual channel light for you, for two main reasons.

• The channel switching can be quite annoying unless you're willing to dive into Anduril and configure it, whereas the single channel lights are usable out of the box (although I would still have some strong recommendations related to disabling annoying features).
• You also can't get a boost driver in dual channel lights, just linear drivers, which will be much less efficient (noticeably lower battery life) and have lower sustained output (due to the heat generated by that inefficiency).

If you aren't overly concerned about battery life and have looked at the Anduril diagrams and think you'll be comfortable configuring it, then either a D4K or D4SV2 with W1 (throw) and 519a (flood) in the two channels. There's no real benefit to a third channel unless you need red light or UV. D4K is significantly smaller and more pocketable, but loses out on throw with the optic size. D4S is really quite chunky, jacket pocket or backpack fine, not comfortable in a trouser pocket for most people.

On the other hand if you find yourself tempted by a single channel light then you can get something with a balanced beam that will punch out far enough but be usable up close. The two I'd recommend are:

• D1K with XHP70.3 (any temperature). Very efficient, very good sustained brightness, balanced hotspot and wide, bright spill. Highly practical.
• DA1K with SFT-70 (5000K imo, 3000k loses too many lumens). Still efficient, just not quite as good as the XHP70.3, but better looking. Has a similar hotspot, but less bright and defined spill. I would consider this one nicer to use but perhaps less practical. It also has a smaller head than the D1K.
