LED Chips, on the Cheap LED bulbs have long been lauded as an energy-efficient alternative to incandescent bulbs. But LED, or light-emitting diode, bulbs are expensive to produce, which has kept ...

The LED chip market is currently exhibiting double-digit growth. These lights are more energy-efficient in terms of power consumption and provide high luminous intensity. They use electroluminescence ...

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 ...

Are you looking to replace your standard halogen turn signal bulbs with something brighter? LED turn signal bulbs have become relatively inexpensive in recent years, allowing vehicle owners to upgrade ...

LED bulbs are a far more cost-efficient, environmentally-friendly option than traditional incandescent bulbs. With a life expectancy of 20 years or more (25x longer than incandescent), the energy ...

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 ...

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been ...

Forget LED light bulbs... in the future, your lighting may be made from carbon. Columbia University researchers have built a light bulb chip that superheats graphene to produce illumination. While ...

A fairly-new LED light bulb went dark the other day and since the housing seemed to be made of some kind of harmless plastic, I decided to dissect the device to see if I could figure out why it had ...
