The numbers you see on the box don't always work out in real life. LED bulbs do last longer, but those claims about five to 10 years are estimates based on internal testing -- and companies are always ...

That means inside every LED bulb are tiny circuit components -- and their soldered contact points -- which are far more vulnerable than the diode itself. The Lighting Research Center of the Rensselaer ...

Light emitting diodes, more commonly called LEDs, are known for their energy efficiency and durability, but the bluish, cold light of current white LEDs has precluded their widespread use for indoor ...

About ten years ago I invested in an LED (light emitting diode) company, and [cutting to the chase] we were too early. The technology and the market did not come together as soon as we had expected, ...

You can help prevent these issues by looking for LED bulbs that have weighty aluminum heat-sink materials but ultimately LED bulbs won't perform the same in high heat conditions. 3. Your home ...

Are you waiting until your incandescent lightbulbs burn out before switching to LED bulbs? Experts agree that from both a financial and an environmental perspective, it makes sense to throw your ...

Like it or not, energy-saver light bulbs are about to become the next big thing. Starting next year, lighting manufacturers will begin a government-sanctioned phase out of incandescent bulbs that ...

The equation to make the inorganic compound combines a lead-free double perovskite with sodium. Physicists at The University of Toledo are part of an international team of scientists who discovered a ...

They’re consistently popular with the readers, which is admittedly part of my (and EDN’s) motivation to continue doing them. But I personally also find them fascinating; inevitably I come across at ...

Efficient LED technology looks set to flick the switch on traditional incandescent lightbulbs forever, say researchers. Look up at the ceiling above you, and chances are there is a centuries-old piece ...
