    Wonderful flashlight

    Do not be intimidated by this light having a UI, it’s quite simple to operate. To be blunt, this fills the niche of being both a useful tool and pocket jewelry with an ability to tinker. With all of the modes and accessories, you can really make these lights whatever you’d like them to be and playing around within the UI itself is both fun and a great way to learn. I opted for the fw4a over the fw3a mainly out of love of the design and a desire to try something a little different than the original. I would highly recommend either light. Higher CRI/2000k-4500k are my preference. If your going to be indoor/up close, to me, the ability to distinguish nuance in color is more useful than overall output. If your outside and want to see something way over there, a higher output say 5000k+ light makes sense. Since this is a pocket flashlight, you can think about the ways you may use it to help make the decision on which LED/emitter to go with. I’ve been very pleased in the few weeks I’ve had this light. It’s been in my pocket most days and is used every night walking the pup. Ramps quickly and lockout is both easy and practical with 2 momentary settings. Definitely a thumbs up!

    Very satisfied with my purchase from Killzone flashlights

    I find it really cool that so much light is able to fit into a pocket. I bought the SST40 in 4000k and the colors are very vibrant, while still putting out a lot of lumens. It gets very hot on turbo, though. I recommend using the electronic lock-out feature when not in use.

    The picture attached to this review is demonstrating how well this light (on turbo) lights up my 3 acre yard. The camera doesn’t do it complete justice, it’s putting usable light on the oak trees from 450 feet. The fence is 6ft tall and roughly 250 feet.


    This is an amazing light. I got this and a lumintop FW3A. It did run very hot on turbo with a 18650 protected battery 20A 3.7V that I had. But using the recommended Samsung 30Q, completely removed the issue. If they make a copper FW4A, I will definitely grab one.
