that gemini also looks like the gloworm x2.
I have the gloworm X2 and X1, so 1200 on the bars and 850 on the head, and that is probably all you need.
People are often saying how bright they are, and in fact I normally only runs the bar light at medium.
Don’t know what the light pattern is but the ‘brighter’ chinese ones I have seen or have just don’t seem as good and you need to run them full to have the same effectiveness as the gloworm on medium. Plus the light ‘color’ is much nicer.
I bought a nominally higher rated fluxient for a mate and was disappointed in it compared to the gloworm.
I also had the 1000 lumen T6 Fluxient torch that torchy’s site shows as much more powerful than the 400 lumens mk 7 joystick, but in reality the exposure is nicer with a better pattern and color.
