I might not be interpreting your statement correctly, but there are quite a few high output hand held flashlights that have pocket clip options and others that rest in compact belt holsters that would be very appropriate for patrol (or other) use. This isn't really the thread to discuss those without going pretty far off topic, but there are certainly options available. I'd look at something that runs on one or two 18650 batteries so that both your H600 and hand held flashlight could use the same batteries.
My apologies as what meant was that the Zebralight handheld high output lights didn't look like they have an optional pocket clip. I do have a Jetbeam RRT-0 that has an aftermarket titanium pocket clip.
