I'll add to the suggestions for the MH-27.
I was just looking for a light, and my requirements were fairly similar to yours. Good thrower on 1x18650, but not one of those ones with the colossal reflectors/heads.
After considering the Olight M-23 and the Nitecore P12GT I went with the MH-27.
The MH-27 has the new XP-L HI V3 diode which is domeless from the factory, which has some advantages over other lights that are "dedomed" like the Vinh mods or the Olight M-23.
That, and the quality on the MH-27 is amazing. All around great light, I highly recommend it.
