Japan develops the world's first rechargeable straight tube LED energy saving lamp

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, in the event of a power outage, the lamp can last for up to 12 hours, and the lamp life is 50,000 hours, but the price is high, at 19,800 yen (about RMB 1,500).
