Ok, GB, let’s see where the rabbit hole leads us!!
Not the best, but it is not the worst! I believe some of us would suggest “FireBeam” just because! 
If this is supposed to be a new brand from your company, chose the name well so that it can stand as a known brand of lights among others!
Ok, what do you mean by “key focus”? Is is a zoomable flashlight? Or do you have to push a button to adjust the focus?
Also, and after Agro suggestion, what is that lens? Is it a dual LED flashlight?
If so, does it have optics, or reflectors?
A lot of info is missing here…
Ok, 1000 lumens seems of for generic uses!
But, continuing the questions, what LEDs will it have? Will it have a good heatsink internally?
More, what type of driver will it have?
Also, will it have e-switch or mechanical clicky switch (reverse/forward)
Honestly, you have 3500mAh batteries that can be put inside the flashlight to increase its runtime. So, why put 2600mAh batteries? Is it to spare time while charging? If so, wouldn’t it be better to have longer runtimes instead of having to charge the battery more often?
Also, if charging “fastly” is a plus, to be able to use the flashlight quickly again, why not use USB-C and fast charging with a 3500mAh cell? (don’t know if this makes sense, but correct me if I’m wrong about this suggestion!)
About water-proofness, will that ring on the tail be well isolated due to the screw/unscrew movement?
Again, it is not clear what type of beam the flashlight will produce, so that information would be important to have to better analyse this User Interface!
I am also of the opinion that “flash” (strobe, I suppose) should be hidden, this is, it should not be in the main interface!
Another question: to get “floodlight low” do we have to go through all the modes [Spotlight high – spotlight low – floodlight high] to get that mode?
That is terribly annoying!
Also, does the flashlight have memory? Or does it always start on HIGH (1000 lumens)?
There are many things to be answered here Gearbest, so that we can give proper suggestions!
Still, hope the questions help you to get answers and to make a good flashlight!
