sufficient light, such as windows, balconies, even fluorescent lamps, incandescent lamps, and it can also be used for hand-cranked power generation in rainy weather (charging The time varies depending on the light intensity)
2. VERY LOW POWER CONSUMPTION: the brightness is greater than that of ordinary light bulbs, and the spectrum is close to natural light, which makes it easy to debate the true color of the object.
3. DURABLE: the life span is more than 80,000 hours, almost no need to consider the problem of replacing the lights.
4. HAND-CRANKED POWER GENERATION: hand-cranked self-power generation and solar charging technology, batteries and bulbs do not need to be replaced, energy-saving and environmentally friendly, hand-cranked for 3 minutes, can be continuously lit for 10-20 minutes.
