A handful of buildings in California are beginning to try a new kind of indoor lighting: sunlight without windows. It’s called hybrid solar lighting, and it is being marketed by a company called Sunlight Direct. During the day, sunlight is captured and channeled into lighting fixtures, then at night, the fluorescent bulb takes over. On… [Continue Reading]
A start-up company is offering mercury-free, energy efficient, high-brightness LED lights to replace typical light bulbs in homes and offices. The EcoLED lights use 1/10th the electricity of incandescent light bulbs, and are estimated to last 50,000 hours before burning out (approximately a decade of normal use). Unlike compact fluorescent bulbs, these bulbs contain no… [Continue Reading]
It’s a 1 watt LED lamp called the Havaleena by Tayo Design Studio. These lights only require three AAA batteries to run, and fully charged batteries provide 20 hours of illumination. Each light comes with four colored filters and they are priced at $59.

So what can you expect from an LED floor lamp? Well, white LEDs will emit a concentrated, bluish-white light. So these lamps are great for accent lighting. As… [Continue Reading]
Most modern buildings don’t take full advantage of daylight. Here, in the Plaza at PPL Center, a dramatic eight-story central glass atrium brings natural light deep into the core of the building, while extensive perimeter glazing provides abundant daylight.
Here’s a new LED Desk Lamp from Koncept. It features 66 “super bright” LEDs. The IceLight is about as bright as a 40–60 watt incandescent bulb. A single bright white LED puts out about 1.7 lumens of light, so 66 of them produce about 112 lumens. This 112 lumens is focused in a 50-degree viewing… [Continue Reading]
Dimmable compact fluorescents are available, they are usually made with “cold cathode” technology. You can find dimmable bulbs here on Amazon.

LEDs are close to becoming metaefficient alternatives to regular light bulbs, but they are not quite there. Right now the brightest LED bulb is equivalent to a 25W incandescent bulb. The bulb seen here has 36 LEDs and runs on 1W. That means it could run 10 hours a day for a whole year for… [Continue Reading]
