Compared to incandescent lightbulbs, LEDs produce a lot more lumens per watt of input power — they’re more efficient at producing light. Of course, that means that incandescent light bulbs are more ...

Sometimes the most useful hacks are also the simplest ones. A case in point is the LED and resistor assembly that [Skippy] recently posted on his blog. The idea is to solder up some pre-made ...

Outdoor LED lighting projects can save energy, but they can also make light pollution worse. Late one evening in June of 2016, John Barentine stood alone at Mather Point, an iconic and rarely empty ...

LEDs with low polarization in a direction similar to standard LEDs show greater efficiency at higher power by resisting 'efficiency droop', a new study shows. The findings open the door to a new ...

A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an ...

First used as status and indicator lamps, and more recently in under-shelf illumination, accent lighting, and directional marking applications, high-brightness LEDs have emerged within the last six ...

A semiconductor wizard who made his own RAM turns his attention to blinkenlights ...

Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future. A hybrid form of perovskite -- the same type of material ...

Just before Christmas, I took my kids to the Brooklyn Botanic Garden for an exhibition called “Lightscape.” Neon lights electrified trees and made the gardens glow. In one large field, hundreds of ...

LED bulbs are energy-efficient and designed to last for many years, but here are a few lesser-known features to consider when weighing a jump to LEDs. Martin LaMonica is a senior writer covering green ...
