I have been using SF47 and SF47T for a while. These two are very impressive for me. I would like to say SF47 is one of the brightest, most powerful flashlight and SF47T is one of the most powerful thrower.

SF47 which can pop up 9000 lumen, reach 522m. and sustain pretty decent of time. 9000 lumen for maximum output, you will get 495m for beam distance obviously this is going to be very flood light. It is a great tool to help light everything around you.
SF47T is a long range thrower. It can light up things out of 1100m and has incredible working time. It features two switch buttons, tail switch to turn ON/OFF, side switch to cycle through modes. If you are looking for a slim and portable thrower flashlight for camping, and security, SF47T is a good choice for you.

As Picture Shows, SF47 is shorter than SF47T. SF47 delivers a different hand-feel from SF47T. SF47 features good weight distribution, when I held it, I felt the whole body was steady and balanced. While I held SF47T, I felt that its head was a bit heavier than its tail since its deeper reflector. SF47T utilizes deeper reflector helping give that slight edge for throw.

Pictures explain their differences. One difference doesn’t show clearly in the picture is their switch.

Which one do you like, long-ranger thrower or high output flood flashlight? Anything you want know or any suggestion for improvement？
