LED Bulb with 18650 rechargeable battery, 15W, E27 base, energy-saving

Description

This LED bulb with a built-in 18650 rechargeable battery and E27 base is a practical fix for frequent power outages. The battery charges from the mains while the bulb runs normally, and when the power cuts out it keeps shining on backup power. Because the 18650 battery is easy to swap, you can buy a higher-capacity cell (for example 3600 mAh) and multiply the backup runtime. The bulb can even be switched on without a socket, just by shorting the contacts — no extra devices are needed for charging or operation.
