The rechargeable LED lightglobe
Now here's something we've never seen before – a rechargeable lightglobe. Chinese company Magic Bulb has patented a new type of device which incorporates a battery and LED lightblobe to produce a lightglobe which uses only 4 watts but produces the equivalent light of a traditional 50W globe. If the power fails, the globe will keep running for around three hours or it can be screwed out of its socket and the handle extended to turn it into a bright torch.
The Magic Bulb was on show in the China section of IFA in Berlin this week and is expected to retail for between US$30 and $40 when it finds distribution in other parts of the world. Does it have a significant and viable point-of-difference to other globes – you betcha!
It's a set and forget solution that will almost certainly come in handy when the electricity goes down next. It has a life of 20,000 hours, saves over 70 percent of the power used by an equivalent brightness 50W filament globe, and meets all the international standards.

I saw things like that more than 20 years ago: what is patented? the bulb-shape? whats the difference between that, and a normal emergency lamp?
It may be easier to have large scale production of OLED. Efforts are on to combine fluorescence and phosphorescence to create the most efficient organic white light emitting diode. GE will use a high-speed roll-to-roll production process that is significantly more efficient.
Imagine the complete walls of rooms illuminated with soft OLED lights!
