Cutting Edge LEDs Contain Spy Cams to Keep People Safe
Airport security is notoriously tight. Every year since 9/11, airport security has been revolutionised. Now, boarding an aeroplane has become a complex routine requiring you to take off everything from your shoes to your belt to your watch. Generally, when we leave the airport, we breathe a sigh of relief; happy that the whole process is over. -
What came first the LED Dimmer Switch or Dimmable LED's?
The main reason that LED's flicker when dimming them is that the LED(s) and dimmer switch are not compatible. Dimmable LED's were only introduced to the World in 2009; the first one I know of was the Philips 7W GU10 LED. How did Philips create this without an LED dimmer switch? They must have tested it using conventional dimmer switches and done batch tests with many different brands and kept testing it until they got achieved smooth dimming results.
