This is no ordinary lightbulb. It is the same size and shape as a regular LED bulb but in fact, it is battery powered, comes with a solar charger and can even serve as a Power Bank.
The bulb arrived securely packaged in a plain brown box, a more attractive branded box would surely help with sales, inside of which was the bulb itself, hanging hook adapter, the Solar panel, short USB charging cable and a User Guide. Build quality seems excellent with noting looking like it is liable to break or fail anytime soon.
The bulb itself, at first sight, resembles a normal LED bulb but on the side, it has two USB slots: a standard size port for power Out and a micro-USB port to charge the bulb. The hanging hook adapter has a robust metal hook together with an E27 screw adapter into which the bulb attaches and a simple and easy to find clicky button on the hook end to turn the bulb on and off. The supplied solar panel comes with a 3m cable with a micro-USB plug to connect to the bulb for charging. Of course, the bulb does not need to be connected to the panel to work as the bulb is powered by an internal 2600mAh battery.
After an initial charge of fours hours, I found that a good day of UK summer sun would keep the battery topped up after a couple of hours of illumination. The internal battery of the bulb can also be used as a Power Bank to charge other devices. This does indeed work but since the output is just 5v/0.5A, charging will be a slow business.
The 7w bulb outputs 560lm at around 8000° K which means it is a good and bright and so cool white light. It could easily pass as a normal household bulb. That said, do not be tempted to connect to an E27 240w light fixture in the home as bad things will happen.
This would be an excellent addition to a camping or field trip. The bulb can be easily attached to the tent frame for use with the solar panel outside for daytime charging.
You can even use it as an emergency charger for a phone. The only real criticism is the l..
