Replaced the TrustFire (this flashlight is a FAKE and a Knock-off) LED Driver with this 9 LED Series 3-Mode Low Voltage Protection for Three li-ion Battery Circuit Board in a flashlight with 7 LED's and 3 26650 KeepFire 5200mAh batteries. WOW! This Driver more than doubled the throw of the light and its brightness overall about the same. I have another Genuine Trustfire TR-J18 flashlight with its standard Driver and 7 LED's and four (4) KeepFire 5200's in it, the knock-off flashlight is now brighter than it is! All I can say is give this Driver a try. It really works.


I had to add solder to the 4 curved solder points to raise them higher to obtain a Ground for the Spanner-Nut (they were too flat to do it on their own). The Driver mount disc is a couple of Millimeters smaller than the original Driver but it still mounts, after careful centering while tightening the spanner-nut.


I think I'll buy another for my Genuine TR-J18 and try it with four batteries instead of three. Close your eyes!!!
