Portable Motion Detecting LED Night Light brightens up the dark

Brenda Stokes, Aug 25th 2008 Discuss [0]

The Portable Motion Detecting LED Night Light is a fun and useful gadget that makes getting around in the dark a whole lot easier. And though it only works at night, you don't need it during the day, anyway. Whether you're walking around the house at night or stepping outside for a moment, this LED Night Light makes getting around easier and safer. It runs on a battery and produces a soft blue light so as to not be harsh on the eyes. A photocell is built in that can detect the brightness of the area. The device will only switch on if it is dark. When the motion sensor is triggered, the LED will turn on and make seeing in the dark easy. The batteries are preserved due to the at-night only function and you can even set auto shut off times. This is a really cool product and for $24.99, it's something you may very well find yourself using once the sun goes down. [via The Red Ferret Journal]

LEDs are known for their efficiency. And that’s a good thing, considering they’re in just about everything these days. But the truly fantastic thing about LEDs is their ability to convert 50-70% of the energy that goes through them into light. However, high costs have prevented them from taking over traditional lighting like fluorescents, until now. The Organic LED, or OLED may be the cost solution, but energy efficiency will be lost, according to researchers at the University of Utah. Read The Full Story
