Sofirn IF19 carries forth the classic design of IF22A. It is a little bit smaller and lighter. Speaking of modes, the IF19 ranges from the low-end 1 lumens up to a blindingly bright 2000 lumens. At that 2000-lumen turbo mode, you can easily see objects at 461m. It runs on a 18350 rechargeable battery. It has good runtime and, at the max brightness, you can run it continuously for 45 minutes. With a tight hot spot and narrow illumination angle, this thrower in some ways outshines other thrower flashlight on the market. The user interface is great, providing easy access to toggle between modes. it also has a longer tube with a clip (sold separately) so you can use a 18650 battery.
