Large drops in light power. I also read that this diode (4000lm) gives strange colors. There are even great power drops from high mode in a matter of seconds.
Hello sir. The strange things about this light for me is it can turn on both lights at the same time. The led is fine for me. I agree with you that the brightness drops quite fast. But when I went out cycling with this light, I found that the brightness drops not as much as when you hold it. That's maybe because of the wind that cools it down. Thanks for watching sir 😊.
