Solarforce Heads

Need a thrower head for my gladiator,already got the k3 flood light,nice by the way,I’ve looked at the m3 and mpp1 but neither have real throw.Anybody got any ideas or want to build me one or modify one?I would like at least 500 yard throw and able to run 2-18650 or 4 cr123.Runtime is unimportant ,its just a toy so I’m open.

M3, de-domed XM-L U2 will hit 610 yds. 4.28A on a Qlite 105c board. Single 18650, but the driver choice would take care of that.
