There are very limited adjustable beam lights, and even more so with higher output flashlight. To get more flood pattern, you will need a smaller reflctor on the same emitter or a larger Die emitter on the same reflector size. SST50, P7, MCE are larger die will usually will be more floody but they also have a higher power consumption. XP-G is more efficient but in a smaller Die which means that they will tend to be more of a thrower unless the reflector is fairly small.

I just got some S Mini lights from Shiningbeam. It uses the XP-G emitter but since the reflector is very small, it cast out a more of a floody beam. I measured a hotspot beam of about 40 inches wide shot from a distant of 15ft. I bought three of those and when I put two side by side and compare them to a Magicshine 900, it was almost the same bightness and beam pattern. The rated lumen is 360 but probably 270 OTF. I did do a runtime and got 3hrs of runtime with the battery voltage still at 3.3 volt and some decrease in lumen. It finally shutoff at 3hrs and 7 minute at 3.28 volt from the AW2900 mah 18650.Ideally if you can fine a small flashlight in a small reflector package using the newer XM-L emitter(larger Die than the XP-G) driven at 1 to 1.5 amps, then that will be best. Darn thing is so small, it makes a good helmet light without the battery pack.

The other choice will be using a host and different P60 drop in and try out different emitter like the MCE or SST50 to get more flood. The good thing with drop in is that you can upgrade to try different emitter as they come out. The bad thing is that some are undriven because of the limited design to dissipate heat. Regardless, most will still have more output than the Romisen.
