CREE XM-L T6 Super Bright, 3800 Lumen 3x LED bicycle lamp, headlamp, flashlight CREE3X3800 (household goods)
The lamp works very well, but the battery is very weak. After a short time, the light is then unfortunately quite. That's not at all good, because then you have no light when you need it. Quite bad, in the event that you use the lamp in the dark. Ser
