Professional, waterproof bicycle light Esperanza Helcules Pro 8300 LX has two powerful white Cree T6 LEDs that emit a strong light with an output of 8300 lux in max mode. The super powerful light evenly illuminates the road up to 200 metres in front of you and is visible from over 2000 metres. Built-in rechargeable batteries, charged via micro USB, with a very large capacity of 4000 mAh, allow you to use the lamp for a long time (up to 36 hours in Super Econo mode and up to 100 minutes in Max mode), which is one of the best results with such a high light output. The lamp has eight built-in lighting modes that can be changed by pressing the power button. The battery charge indicator shows the charge status of the battery.
