If you've ever had the power go out in your home, you already know how useful these Lightglobes from Magic Bulb can be. One of the most annoying things about a power outage is the abrupt cessation of light. All your light bulbs
going out at once and thus being plunged into darkness without warning is disorienting, annoying, and can even be dangerous depending on what you're doing.
Flashlights You Can Screw In to Light Bulb Sockets
The Chinese company Magic Bulb has a great solution for this situation and any like it. Their Lightglobe light bulbs are basically LED flashlights with standard medium base light bulb sockets. These combination LED light bulbs/flash lights run on four watts of power while providing about as much light as a standard 50 watt incandescent. The built-in rechargeable battery can run the light bulb for three hours at full power; when the power goes out, the Lightglobe keeps running! You can even unscrew it for use as a flashlight if need be. That's great versatility.
Energy Efficient LED Light Bulbs
Such a device is possible because of the extremely low power consumption of LEDs. Very little heat is generated and so extra electronics like rechargeable batteries and on/off switches can be combined with LED light bulbs to create flashlights that can be screwed in to ordinary light sockets. The low heat also makes it possible to hold the light bulb as a flashlight; at four watts it will never get hot enough to cause harm to anything.
Magic Bulb's Lightglobe LED light bulbs are expected to cost around $30 to $40. Not too shabby a price for a rechargeable light bulb that is also a flashlight. Count in the tremendous long life of LED light bulbs
and you've got an extremely useful item that could very well save your life!
