CNY companies develop a better light bulb

The old incandescent light bulbs are on the way out, and a team of companies are jumping in with a new generation of efficient LED lighting. The LEDs are about as close to natural light as a bulb can produce. They're also more efficient and less expensive over the life of the bulb. It's a technological leap. "We talked about this next LED going from like the Commodore 64 to the iPad," said John Johnston of ProTerra LED. One of the products developed by the team of companies is a model that can replace an existing florescent bulb. It'll last years longer and use 80 percent less energy.

LEDs the shining star at trade show

First they took over our radios. Then our televisions, stereos, watches, toys, telephones, computers, and just about everything else. So is it any wonder that semiconductors are threatening to transform the lighting industry?

That's the lesson of this week's Lightfair International at the Convention Center in Philadelphia, where light-emitting diodes, or LEDs, are the obvious stars of the show.

More Beautiful Than A Bulb Could Ever Be

A joint venture between JOBY and designer Peter Stathis has produced a 102-diode LED lamp that may win over even the most ardent lovers of incandescents. For their Trapeze lamp, Stathis and JOBY (makers of that famously clever flexible tripod) designed what they call a "flat panel light engine" to serve as the lamp-head.

Kumho Introduces Direct Replacement LED T8 Lamp

Kumho Electric is introducing the Earthcare Direct Replacement LED T8, a lamp that can simply be snapped into an existing fluorescent fixture, freeing maintenance contractors from the time consuming, costly process of re-wiring T8 fixtures to accommodate an LED lamp.
The advanced, patented design also provides for full dimming control using a standard dimmable T8 ballast and incorporates environmentally friendly passive components that offer a more reliable, longer lasting product.
"Our Earthcare T8 LED utilizes a first-of-a-kind, revolutionary design," said Kumho Electric USA president Alan Medak. "It makes switching to LEDs as easy as changing a light bulb and works with popular instant start ballasts. No rewiring or special handling is required."
Using one third less energy than a traditional linear T8, the lamp offers instant brightness, producing a 110° beam that spreads illumination uniformly, without hot spots or glare.
The lamp maintains brightness over its 50,000 hour rated life with low lumen depreciation. It also operates at a moderate temperature, reducing load on building cooling systems. The lamps are environmentally friendly, producing no UV light and containing no mercury.
The Earthcare T8 LED is well suited for difficult applications, such as refrigerator/freezer cases, high-vibration situations, or hard to reach locations.

When good lights go bad: LED breakdown

LED light bulbs augur tremendous reduction in the electricity used to light homes and offices around the world, but quality and pricing issues are keeping consumers at bay for the moment. So said LED experts and entrepreneurs on a panel discussion at the Cleantech Forum in Amsterdam, noting that mass adoption will not take place until prices fall – they can be €20 in Europe and $40 in the U.S - and until quality stabilizes.

If CFLs are burning out, check the bulb

Changing to compact fluorescent lamps is a popular way these days to help save energy. This process can take time as you replace light bulbs as they burn out. CFLs may be more expensive to purchase, but they save money in the long run. CFLs have a longer lifespan than incandescent bulbs. If you are burned up by what you perceive as early burnout of CFLs or bulbs, it may be the CFL bulb selection and use causing the problem.

LED bulbs move in and mix up home lighting

In the space of a few years, I've gone from one lighting technology to another and now to three lighting types in my home. I suspect others will be in the same shoes as lighting options expand, notably those involving LEDs. Eager to cut down my electrical load, I essentially converted to compact fluorescent lighting (CFLs) years ago. Recently, though, I've replaced CFLs with efficient LED bulbs and even energy-hogging incandescents to address an unfortunate feature of CLFs: turning them on and off frequently degrades their life.

The LED Promise Land : A Connexion Market Perspective

Compact fluorescent lamps are a temporary but still viable alternative to energy-efficient lighting. Think of CFLs as the bridge that connects our older, less efficient lamp technology to the LED promise land. Increasingly more lamp manufacturers are devoting larger shares of their R&D resources towards developing the LED promise land and less so within that CFL bridge. The lighting industry is clearly banking on LEDs as the final replacements for incandescents.
The reason LEDs have not yet displaced CFLs from the market are twofold: the first generation LED bulbs had a narrow and focused light beam, and the cost of LED technology is still too high. With this said, both CFL and LED technology are viable options today when looking for a replacement for incandescent lamps.
We can't stress enough that this lamp technology market is no different than any other emerging market. There are numerous profiteers in the market spewing forth their too-good-to-be-true claims and misinformation for the sake of the quick sale before the dust settles and the facts surface. The old axiom, 'if it sounds too good to be true it probably is', certainly applies here. The U.S. market is flooded with cheap LED products manufactured overseas with inferior components that produce low light levels, that can't possibly live up to their exaggerated energy saving and long life claims. Unfortunately, these cheap imports are being sold on well known web sites and through big box retailers.
Also worth noting are the many so-called 'manufacturers'  who are in fact resellers and simply repackaging the same inferior products offered through the import channel. And to further add to this confusion, are the more reputable manufacturers that offer a lesser grade LED lamp expressly for the consumer market and a higher grade for the commercial market. As you probably guessed, the commercial grade products come at a higher price point and perform significantly better - but are easily confused with the lower priced consumer grade products. If you're making your decision solely on price, you may be setting yourself up for disappointment. The keys here are Lumens and Lumens per Watt Efficacy. This is where the Lighting Facts label comes into play. The Department of Energy (DOE) is an advocate for quality and has established the Lighting Facts program to ensure that the LED products you find on the market meet your expectations for performance. These products include LEDs for everyday lighting purposes, such as table lamps and outdoor light fixtures. They do not include flashlights, nightlights, or holiday lighting.
Participating manufacturers voluntarily pledge to report their products' performance results. Those results appear on the Lighting Facts label, which those manufacturers must include on product packaging or in the product literature. Retailers and other industry buyers can then make informed purchasing decisions for their lighting inventory.
