LEDs are the focus for the future of lighting, even as manufacturers struggle with the business model of selling a bulb that will last for decades. “We are not spending one dollar on research and development for compact fluorescents,” says the CEO of Philips Lighting. Their R&D; is invested in LEDs. The success of LEDs in lighting effects for public buildings seems assured. In the home the price of an LED bulb needs to be low enough for consumers to see value in its longer life, with manufacturers still taking a profit, or perhaps the home lighting design paradigm needs to change.
