Solar Emergency LED Bulb (E27 / B22)
A standard-fit bulb that keeps glowing when the power cuts — 3W/5W in E27 or B22, with a built-in 1800mAh LiFePO4 battery, auto-on in a blackout and 4–6 hours of backup.
The simplest blackout product to sell: it looks and fits like a normal bulb (E27 or B22), but a built-in LiFePO4 cell keeps it lit when the power cuts — automatically. It charges while the grid is on, or via USB or the included mini 3W solar panel when it isn't. For distributors in outage markets, it's the fastest-moving impulse SKU because everyone already has the sockets.
