Schematic of the new street lamp

For astronomers, a well-lit city means a sky unavailable for study. Worse, light pollution is blamed for affecting bird migration, sea turtle hatching, and wildlife mating and feeding routines. Researchers at National Central University, Taiwan, and Unidad Academica de Fisica, Universidad Autonoma de Zacatecas, Mexico, have attacked the problem with a new LED street lamp designed to shine only where needed, without splashing into unwanted areas, as a way to reduce light pollution while providing better lighting.  Read More

Klauf Lighting's Joseph Lee with the Klauf Light Bar

The latest LED lighting product to hit Kickstarter, Klauf Light Bars are semi-portable, low-cost LED strips which can be connected end-to-end more or less straight out of the box. They come in 6-inch and 12-inch (15 and 30 cm) lengths, which can be arranged as you like up to a length of 15 feet (or about 4.5 meters). They can either be slotted together directly or connected with cables, which is handy if you intend to install them under kitchen cabinets which extend around a corner (recommended), or make giant illuminating nunchaku (less so).  Read More

Philip's Coen Liedenbaum shows off the 200-lm/W prototype LED tube

Back-to-back announcements from Green Ray LED and Philips show signs that there is now clear water between LED lights and fluorescent lights so far as energy efficiency is concerned. The proverbial glow of commercially available lights with 200 lumens per watt efficiency can now be clearly seen radiating over the horizon.  Read More

How do you measure the life of a light source that could last decades? (Photo: Shutterstoc...

Just over a week ago we reported that Philips' 22 W LED light bulb, designed as a like-for-like replacement of a 100-W incandescent light bulb, was the first LED bulb of its type to receive the stamp of approval from Energy Star. But looking at the Energy Star requirements reported by Philips in its press release, it seemed a little strange that Philips' product is the only one to have been certified – given that products long on the market appear, at face value, to meet those requirements. Since then, Gizmag has spoken to LED light bulb makers Switch Lighting and other industry players to find out why they're apparently playing catch-up.  Read More

Gizmag takes a hands-on look at Photojojo's Pocket Spotlight photographic light source

Never before have I so wished that I could use a device for taking photos of that device. That was certainly the case with Photojojo’s US$30 Pocket Spotlight, however. It’s simply a tiny battery-powered array of 32 LED bulbs, that provide a source of soft, even light as an alternative to the harsh light of a flash. While serious photographers will already have proper lighting systems of their own, it’s a nice tool for all the point-and-shooters out there.  Read More

Audi's concept OLED taillight, Swarm

Practically, this may be a terrible idea, but as a tech demo, it's an excellent illustration of OLED, and its potential to kick holes in the divide between what we think of as display technology and what we think of as lighting technology. The concept is called Swarm, and is in essence an ultra wide aspect ratio TV placed on a car's derrière where the taillights should be. The idea is that the swooping, fluid animations displayed will relay all sorts of useful information to other road users.  Read More

The Lumio is proving popular with Kickstarter backers

Good news for lovers of things that look like books but are not books: the Lumio LED lamp we wrote about in January has bulldozed through its US$60,000 Kickstarter target, nosing ahead of $450,000 with 7 days of the campaign remaining.  Read More

The Luxi incident light meter on an iPhone

For professional photographers, an incident light meter is rather important. Unlike a reflective light meter, which measures the amount of light bouncing off a subject, an incident light meter measures light before it reaches the subject. This is helpful in situations where lighting is inconsistent. A new product called Luxi is designed to turn your iPhone into just such a light meter.  Read More

There are no holes in Alexander Lervik's idea

At the bleeding edge of LED/chocolate crossover technology, Alexander Lervik's Lumière au Chocolate is but the latest example in the burgeoning field of edible lighting.  Read More

The light is easy to reposition with the Ultrapod

The new UCO LumoraPod Utility Light transforms to meet a multitude of tasks. With a few simple adjustments, it becomes a flashlight, lantern, lamp, work light and more. It can serve as a one-light-fits-all around the house, at the work site and in the great outdoors.  Read More
