UniqueFire UF-G7 is good,from WillBuying
Just got this today. It isn’t a host. Brighter than I expected, but not as nice looking at the ones above.
EDIT: This is a nice light. It actually has an XML and good mode memory and mode separation. Very nice smooth throwy beam. High end of neutral white. Gets hot fast for stainless steel. Haven’t checked current yet, but it puts out a lot of light.
Same(ish) light on Aurabuy for $12.62 to use as a host. Note: I don't know if it can be modded easily or not.
