Blackouts are not a problem anymore!  Never be left in the dark again.  This Energy-saving Emergency LED bulb with a medium screw base can be operated using a wide input voltage range (85V to 265V).  The internal battery charges when the light is on, then automatically switches to emergency mode whenever there is a blackout.  Using super-efficient LEDs, it can produce the same amount of light a s a 60 Watts incandescent lamp using only 9 Watts of electricity, while lasting more than ten times longer.  
Universal Voltage: The wide voltage range (85V to 265V AC) means that this bulb can be used in most countries with no problem.
Power and Output: Using only 9W, this bulb can produce as much light as a 60W incandescent bulb.  The super-efficient LEDs, along with the highly transmissive haze cover ensures uniform light output with no dark or bright spots. In emergency mode, it lights up at about 50% for approximately 4 hours.
Construction: This super-lightweight bulb is compact, vibration-resistant, and constructed of aluminum and heat-resistant polycarbonate.
