Since LEDs are an efficient light source and draw far less power than traditional bulbs, they are perfect for off-the-grid applications where solar cells charge a battery that powers the lamp. Large-scale applications of this concept include LED road lane markers, but smaller-scale projects like lighting your lawn or garden are perfect uses for them

Sharp is introducing a new range of solar-powered LED streetlights. These self-contained lights charge during the day, and switch on automatically when darkness falls. They can operate for 10 years straight without maintenance. They make use of new, high-intensity LED spotlights, which are ideal for public parks. The LEDs illuminate with a directed light and

Last year, we featured a nightclub lit entirely by LEDs, but here’s an office building that is said to be the first to be lit by 100% LED light. The lighting was provided by the Netherlands-headquartered Royal Philips Electronics. To showcase the potential of LED light, Philips designed the lighting system to be warm and

Last year, Philips showed off their LivingColor lamps at a media event. Each compact light can illuminate 16 million unique colors, all of which can be controlled via an included wireless RF remote. You can set any remote to control up to six fixtures simultaneously, keeping their colors in synchronization for a dramatic effect. Since

OLEDs are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. They’re so thin, that they could be applied to rooms as a type of wall paper to glow at the touch of a finger or when someone enters the room. Like LEDs they produce light very efficiently. But

This “Rotondo” rechargeable lamp uses LEDs for illumination — it will run for about eight hours before it needs a recharge. The lamp is also water resistant and is made with mouth-blown parnaterraglas with a frosted finish. It will cycle through a spectrum of colors, and can be stopped when the hue you desire is

This is a great innovation — the streets of Europe could soon be lit by "solar trees". These self-contained streetlights could save cities energy and money too. Unlike regular streetlights, they do not require costly underground wiring to install, and they are immune to blackouts. Designed by Ross Lovegrove, the lights have 10 solar panels

Hold something in front of these lamps, and the lamp shade will change to the color of the object. There’s a standard light bulb inside, surrounded by a ring of LEDs which project the color onto the shade. These lamps will be released sometime next year by Philips. We also featured Philips’ interactive bulbs in

Apparently red LEDs are 60% more efficient than fluorescent light when growing vegetables hydroponically. According to IEEE Spectrum Online: Of all the colors of the rainbow, red is lettuce’s favorite. Chlorophyll, the electrochemical engine of photosynthesis, runs on red photons. So if you are growing the vegetable indoors in a factory, why waste energy on
