I must be behind the times. I currently have a 6P with a Malkoff M61 with Nichia 219A sitting in the safe. I just don't want to use it too much.
I have another 6P host with a standard P60 bulb that I want to put a drop in module but haven't found anything of interest yet. I will have to research into these 519 leds. Then again I see how expensive these 6P hosts can be LoL (have 6 of them in various configurations.)
Those sportac ones look promising but I had one a long time ago and ended up selling it due to not liking the wall of light.
If you just want some budget options to try out, Kaidomain ones are...acceptable, and you can often add an 18650 or 21700 host for under $10 extra. It's not the best host in the world (painted with low quality paint that chips easily, very sharp edges, no interchangeability with most other hosts), but for the <$10 they are, they can be fantastic. The drop-ins are usually under $15, too, so you can try out a bunch before committing to a more expensive option.
Alternatively, Lumens Factory sells mirror reflector 519A drop-ins that are more like a series of overlapping, concentric hotspots.
You can pick up the LF drop-in with the SP6-M for under $10 more than the bare drop-in (thought, I think that's the orange peel one, which is a central hotspot with diffused spill), and then you have what I'd say is a very nice (the nicest Chinese host I've had), modular host that can use either 18650 or 18350 cells. The sell both 1 and 3 mode variants.
And, for what it's worth, I think only the 3x drop-ins create that "wall of light" effect. I'm a bit with you on those...I'm not sure that's my favorite, haha. GREAT if you're just walking, and want to see EVERYTHING on the ground within a reasonable distance, but kind of awful if you're trying to look DOWN the path, haha.
