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 ...

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 -- ...

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 ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

Designers of early indoor LED light bulbs faced numerous technical hurdles, including AC-to-DC conversion, thermal heat-sinking, constraints imposed by current bulb sizes, electrical transients, and ...

Early adopters of LED lighting will remember 50,000 hour or even 100,000 hour lifetime ratings printed on the box. But during a recent trip to the hardware store the longest advertised lifetime I ...

The color temperature of a light, measured in kelvins, is its most noticeable characteristic. A candle, at 1900 K, appears orange. Daylight, at 5500 K, is much whiter and bluer. A 5500-K bulb, however ...
