Ok for sale tonight I have another light from my collection. This is a 4x Tangspower with de-domed XM-L2 U3's it's running over 4500 lumens on high. BLF FET driver with a zenor mod done. Spring mod done, it takes either a single 18650 or 26650. This is a very heavy duty light with a great beam. This also is a light with the solid construction instead of having a pill it's all one piece.
