Republicans often describe the standards as a "light bulb ban," arguing that the rules would greatly restrict consumer choice by pushing out traditional incandescent bulbs in favor of more expensive, but more efficient, LED (light emitting diode) and CFL (compact fluorescent light) bulbs.

The Post said. An accompanying infographic showed how the lifetime cost of the $50 LED would end up being $5 more than if you stuck with traditional incandescent bulbs. But as the website Think Progress first reported, the math was way off.

Seattle is the fourth city to participate in the survey, following Anchorage, San Diego and San Jose, but it is hard to imagine the others being as enthusiastic.

Wang Wen-chao, chairman of Nan Ya Photonics, pointed out that LED market is going to take off and Taiwan boasts complete LED industrial chain, covering epitaxy, die, assembly, and module.

"Converting our nation's streetlights to LED technology not only could reduce our energy consumption significantly, but also improve the quality of illumination," said Consortium Director Edward Smalley of Seattle City Light. "The Retrofit Financial Analysis Tool will make it easier for cities, utilities and others to analyze the cost benefit of LED street lighting, by providing specific key information on costs and return on investment."

Eight19, a company based in Cambridge, U.K., is one of several companies offering some type of payment plan to make the systems affordable. Customers pay $10 for the solar lighting system, which includes a 2.5-watt solar panel, two LED overhead lamps, and a lithium-iron phosphate battery pack. Then they pay a weekly fee for the power it generates.

Ohio-based obstruction light manufacturer Hughey & Phillips (H&P) has a new LED obstruction light for longer-lasting, more efficient fixtures, specifically in the renewable energy industry. H&P says their Horizon low-intensity products offer a solution for FAA L-810 steady burning lights and can be powered using a solar array for renewable energy applications.

Each week, users buy a scratch card for about $1 from a local vendor. It gives them a number that they text to Eight19 for verification. The company sends them a verification code that they enter into a keypad on the battery pack. The code electronically unlocks the device for a week, allowing the battery to supply power to the LEDs or to a phone charger.

In order to determine where it was, a photodiode in the tag would measure the flicker rate of the overhead LED lights. This predetermined rate would be different in different areas of the store, and act as a digital signal to the photodiode. It would also be undetectable by the human eye. The tag would then report back with its location via the ZigBee system, so the customer could find the product.

Cirrus is setting itself up to ride that sea change as hard as it can. Meanwhile, the audio success provides a stable and growing operating base, even if it's tied to just one enormous customer. And Rhode expects a pretty smooth transition in that relay race: "Once LED starts to ramp, we wouldn't expect that to be in a kind of a one-time, lumpy fashion," he says. "LED lighting is more of a kind of design-in and razor blade, hopefully, model where people are ordering more and more as it goes on."
