I have seen these Keygos Flashlights that are either Ultrafire copies or from the same manufacturer. Both the KE-1 and KE-2 look like the Ultrafire C8, with the KE-5 looking like UltraFire U-80.
Possibly they are the same rebranded or the maker is using a basic carcass and the circuitry is different. I do not know and I am clueless on this subject.
Keygos are generally listed as being 1300 lumen, but more like up to 1000 lumen.
I have written to Keygos to ask the differences, but maybe you guys with them can provide a better review. http://www.keygos.com
The only differences listed are the body type and measurements.

I read in one forum that the heat sink on the KE-5 was glue instead of screwed.
I also read in a translated Russian review something about the battery current!

1) Absolutely honest 900 lumens.
5) Supply of 18 650 single battery - included. Ток потребления 2.5 ампера. Current consumption of 2.5 amps. Что интересно, применять можно только аккумуляторы без защиты, т.к. Interestingly, use only batteries without protection, because при токе 2.5 ампера защита отключает аккумулятор. at a current of 2.5 ampere protection disconnects the battery.
Here is a list of Keygos YouTube videos:

In general the only main thing I can imagine is the reflectors are different. They are all smooth, but I think there might be a difference around the Cree emitter.
Possibly the digital regulated circuitry is below 3000mA Current Output.
I am looking at single cell 18650 Flashlights of the most lumens, highest power, and longest beam throw. Budget of around $32. I was looking at Ultrafire flashlights but now considering one of these Keygos copies.
These 3 models interest me, but I would first like to know their technical info and the differences between them. Plus their weaknesses compared to other similar budget flashlights. But I want to keep the subject on these 3 Keygos flashlights please! Comparison beam shots between them would be super. :)
Ok, something for you experts to get your teeth into. Thanks in advance!
