IFA is great for the tech industry. Every facet of the market has a space to show off their latest and greatest. And while Samsung and LG both took plenty of time to show off their glorious devices, smaller companies tend to hide in the shadows. Which is a shame, especially when it comes to a small company out of China called Magic Bulb. They've managed to create an LED bulb that has a rechargeable battery inside, but that also has another trick hidden up its sleeve.
