Candela LED lamps
Rechargeable LED lamps are fantastic to have around the house because they give off soft light just like candles, but you can leave them anywhere you like without worrying about burning the place down.
Candela LED lamps equally useful on the dinner table or bedside. Patented, intelligent circuitry makes them illuminate automatically when lifted from the charging platter, and start to recharge as soon as they’re put back. They also turn on automatically during power failures so you always have an emergency light source within easy reach.
A set of four rechargeable lights replaces hundreds of dollars worth of wax candles, and they’re cleaner, more durable, and easier to use. Vessel’s SafeCharge™ induction system eliminates exposed electrical contacts, and each light is made of impact-resistant polycarbonate. Long-life warm-white LEDs provide the light source. When the batteries eventually start to lose their charge memory, they’re easily replaced to ensure years and years of light.

Galleria Fashion Store - Seoul
The Building of Galleria West Shopping Centre in Seoul, Korea, is designed by Dutch architects UN Studio, has become the latest, intriguing style icon in the city and a world first for electronic facade technology. Ben van Berkel of UN Studio in association with Arup Lighting in Amsterdam have transformed the Galleria into a perpetually changing, light-reactive and computer-programmable radiant surface.
4330 discs, each 850mm in diameter, make up the entire facade of the mall. They can be programmed to generate up to 16M colours, showing astounding displays in every imaginable shade. At other times the building can even become a giant billboard, its pixels feeding text or images around the entire external structure.
Each disk houses its own LED luminaire. Together with Xilver Lighting, Gronsveld, the Netherlands, a system was created that is capable of producing 16 million different colors for each disk. At night, the individually lit disks respond to a computer program. “Each disk acts as a big pixel on a giant screen,” van der Heide points out. Mounted on brackets, all fixtures are lamped with four LEDs: two green, one blue and one red. Each emits a single watt. “The double green LEDs product a crisp and cool natural hue,” he says. “Typically, color-changing LEDs have a pinkish-magenta cast. The fixtures at the Galleria have an asymmetric throw that places the hot spots off-center. The disks appear to be glowing spheres,” he observes.
Cost of fabricating and constructing the steel structure was approximately $200 per square foot. This amount also includes the exterior steel supporting beams that span from one column to another to support the aluminum frame, the glass disks, LEDs and wiring. Each luminaire cost $55. The custom design and installation of the control system was $40,000.

Balloon Lamp
The BalloonLamp is based on the Japanese Chochin; a portable lamp which was illuminated by candlelight, from the EDO period. Designer/musician Kouichi Okamoto has updated this lamp by replacing the candle with a LED and the paper lantern with a standard rubber balloon. Since the LED light source does not generate any heat the balloon is safe from being damaged or melted.
The balloon also makes a great diffuser for the bright LED. The BalloonLamp is very portable and can be used indoors or outdoors for decorating, camping or backyard parties. It can be deflated after use and easily stored.
