Japanese rechargeable LED energy-saving lamps can be illuminated for 12 hours after power failure

The LED energy-saving lamp has a built-in lithium-ion rechargeable battery. The lamp will charge itself under normal power supply conditions. After 3 hours, it will automatically switch to battery-powered mode illumination. After two hours, it will switch to the normal mode, and the lighting will be cycled accordingly. There is no need to consume extra power in the lighting mode, so the actual power consumption is only 30% of the same wattage of ordinary fluorescent lamps, and 60% of the same wattage of ordinary LED lamps.

In addition, when there is a power outage, the lamp can last for 12 hours and the lamp life is 50,000 hours, but the price is high, at 19,800 yen (about 1,500 yuan).
