Sky Ray King on 3x18650s?

Having just given up one of my unprotecteds to the HD2010 to work with the odd tailcap (stopped the connection problem I was having), I now have only 3 for the King. I charged(re) them and put them in the light. The thing lit up about like it did with 4 cells from what I can tell. I then tried 2 and then even 1 cell. Don't know if I could see a difference in output. I think not. Amazing torch!

The light is a touch lighter, too, but anyone have any idea of the runtime on 3 batteries? And keep in mind, these are lower capacity batteries. Anyone done any real runtime tests on the King?

Ever find an answer?
