GE, one of the world’s most important lightbulb maker, has decided that they need to shift to LED lighting already, in a decision that’s very detrimental to not-so-old CFLs. It’s now been long since I’ve seen people reinventing the lightbulb and betting on new tech like crazy. Each lightbulb technology has its pluses and minuses. […]

LED lights reduce energy bills, this is what we all know. We also know that they require an initial investment, which might prevent us from making that step towards saving money in a long run. The guys at Walmart, however, are no longer letting us find excuses, as they are now launching a new line […]

LED Cities Happy with LED Outdoor Lighting Performance and Savings!

Benji Jerew — Thu, 01 Nov 2012 19:13:42 +0000

Street lighting has come a long way since the early days of oil lamps, gas lamps, arc lighting and incandescent lighting. Sodium vapor lamps in use today are slowly giving way to LED outdoor lighting. With streetlights numbering in the hundreds of thousands in an some cities, one might guess why LED lighting would be […]

More Efficient Lighting Not Necessarily Meaning Less Energy Consumption, Paper Says

Ovidiu Sandru — Mon, 06 Aug 2012 18:39:08 +0000

Two Sandia University researchers, Jeff Tsao and Harry Saunders have recently underlined what you may never have thought of LED lights. Historically, when a new, more energy-efficient lighting source had been invented, people didn’t use less energy, but instead used more light to do work. The first time the idea broke through in 2010, it […]

Toshiba's New Cylindrical LED Bulbs Could Successfully Replace Incandescents and CFLs

Ovidiu Sandru — Mon, 06 Feb 2012 11:48:32 +0000

Slowly but surely, LED lamps begin to replace standard incandescent light bulbs and even fluorescent ones (CFLs), once considered best at saving power. Toshiba just announced two cylindrical LED light bulbs (I prefer calling them “lighting devices,” rather than “bulbs”) that offer the same brightness of a 40W incandescent bulb. The two LED devices will […]
