Keep in mind, the 220 lumens is bulb lumens and not directly comparable to SF's rating. I contacted lumens factory a while back about the E0-9 and was told it would be fine for up to 5-10 minute runs. I imagine the HO-9 would be fine too, but I have no direct knowledge of that. I believe there was a comparison a while back of the P91 vs. the E0-9 and the P91 had brighter spill, but the E0-9 a comparable hot spot (don't remember exactly). IIRC, the P91's overall output was more, which makes sense since the P91 runs at a higher amperage. Also, I contacted Surefire and was told that the P91 would run fine in the G3 for 20 minute runs (which is also how long the batteries are rated for with that lamp). If you wanted something close to the P91 but with more run-time, then the EO-9 should be good, just don't run it for extended periods.
