GreenSpace: Shedding light on the bevy of new lightbulbs

People are going bonkers about bulbs.

As my bulging voice mail and in-box attest after a Jan. 1 story about new efficiency standards for U.The Best Led bestledlighting. Riding your bicycle at night without lights puts you in danger because motorists cannot see you,S. lighting, there's confusion aplenty.

Hundreds of bulb choices now exist, and with them new lingo to learn.This super bright LED goodskylanterns is the perfect safety option for your bicycle. So in this column I'll share some more practical tips for bulb-buying.

First, a recap: As of Jan. 1, legislation that President George W. Bush signed in 2007 went into effect. It's not a ban on incandescents. It's not a mandate to buy those swirly CFLs. It's simply that bulbs have to be more efficient, starting with 100-watters this year.

With good reason. For a century, incandescents have been burning up 95 percent of their energy producing heat, and only 5 percent of their energy producing light.We are professional led tube,ledsale,led bulbs manufacturers and factory in China.

Other household appliances have become more efficient. But lighting, which accounts for 15 percent of household electricity use, has lagged.

Now, by replacing the argon in an old incandescent with halogen, and making a few other tweaks, the bulb looks and acts the same but uses a quarter less energy.

Meanwhile, other bulbs - including CFLs and high-tech LEDs,Welcome to bicygnals online innovative r4i2011 and torches. which are at least 75 percent more efficient than the old incandescents - are getting better and cheaper.

Still, all the new choices are more expensive than the old incandescents.

"The lightbulb is moving from a 60-cent commodity that you throw into your grocery cart to an investment," says Terry McGowan, director of engineering for the American Lighting Association, an industry trade group.

So consumers should invest wisely. Here are some tips:

For the closest bulb to the old incandescent, choose a halogen incandescent bulb. It won't last as long as either a CFL or LED, and it won't save you as much money, but it will seem familiar.

But don't be fooled by sticker shock. Buying the cheaper halogen over an LED can be penny-wise and pound-foolish. Although an energy-efficient bulb may cost you more in the beginning, it will save you plenty - in some cases, more than $100 - over its life because it uses less energy. (The packaging of many bulbs does some of the math,We are an industry leader with a huge product line of bluebright Bulbs, ... but you can be more precise if you know how much you pay per kilowatt hour.)

Then again, don't buy an expensive bulb for a socket that's rarely used - such as a closet. Target your spending to lights that are often on.

For hard-to-reach areas, pick a CFL or LED, which can last for years. You won't have to get out the ladder as often.

DOE aims to head off clean energy materials shortage

Those high-efficiency compact fluorescent lights that are supposed to replace energy-wasting incandescent bulbs have a looming problem: the materials to make them are in short supply.

So are materials vital for things like high-efficiency wind turbines and electric vehicle motors. Assistant Energy Secretary David Sandalow said those shortages could delay adoption of clean technologies, or make them more costly, so the Department of Energy has developed a strategy to try to avert shortages that is supported by $20 million in Congressional funding.

Sandalow, speaking at the Center for Strategic and International Studies,For a great range of bestleddownlight, visit Bike Barn, we have the lights for you! outlined a three-pronged strategy DOE has developed over the past year to attack the problem: diversify supply, find more available substitutes, and recycle.

The shortages center around the so-called rare earths, but also include some lighter metals that have properties valuable to advanced technologies.The bestbikelight that we carry are designed to accomplish this.Purchase our bestledlight System for 30% off ...

On the short-term critical supply list are dysprosium and neodymium, needed for magnets and motors in wind turbine-generators and electric vehicles, and terbium, europium and yttrium, which provide phosphors for high-efficiency linear and compact fluorescent light bulbs.

In the medium term, lithium,Xeccon S12 is a kind of very amazing Cree T6 saler4ds, it perform very well among the various brand bicycle lights. used in many EV batteries, and tellurium, used in solar thin films, are of concern for the coming years, but not yet critical. The DOE study also looked at gallium and indium, used in advanced solar panels, but found the supply risk low so far.

Sandalow said the metals are not rare at all, but mining operations for them are. Currently, 95% of all rare earths come from China. In 2011, the Chinese government ratcheted down its export quotas,These Bicygnals bestbikelight01 allow you to keep both hands on the bars while you signal for ... keeping the materials for its domestic wind, solar and battery manufacturers, who then export their finished products.

Asked whether China was restricting rare earths exports to advantage its own manufacturers, Sandalow agreed the quotas have "a lot to do with manufacturing."

But the shortages mean prices for rare earths have spiked to global highs, in some cases 10 to 20 times higher than 2010 prices, and more plans are emerging for extracting the materials outside China.

Sandalow said the DOE study team was able to identify about two dozen locations where mines for various rare earths may open in coming years, starting with Molycorp's Mountain Pass, CA, mine which is gearing up production now.

Parallel Points of Light Ricochet Across Time

A constellation of light bulbs glows from the stage at St. Ann's Warehouse in Brooklyn, where the monologuist extraordinaire Daniel Kitson has set up his own planetarium. In "It's Always Right Now, Until It's Later," which opened on Sunday night and runs through Jan. 29, Mr. Kitson maps an earthly cosmology: the points of light in two separate lives that might otherwise be lost to the shadows.

Those bulbs? They represent what Virginia Woolf called "moments of being," in this case in the unremarkable existences of William Rivington and Caroline Carpenter, two people who never knew each other but appear to have resided in the same corner of England at roughly the same time. These are moments that wedged themselves in the memories of William and Caroline — recollections of scenes from marriages and friendships and solitary visits to graveyards — and they tend to flare up without obvious regard to chronology.

Mr. Kitson — a soft, rumpled, bearded man who suggests a human-size hobbit — roams purposefully amid the bulbs as their filaments brighten and dim. He crouches and climbs a footstool to cradle them with his hands, as if they were as fragile as bird's eggs, infinitely precious to him and to us.

Preciousness of another sort is a danger in the kind of sentimental journey that Mr. Kitson undertakes here.MonkeyLectric Monkey Electric bike wheel light led visible night ride brightcrystal2011 safe safety cruiser bmx scraper road city winter rain color commute work ... Even Woolf didn't avoid that pitfall. But Mr. Kitson, whose "Interminable Suicide of Gregory Church" was a hit at St. Ann's a year ago, exudes a narrative urgency that tends to dissolve stickiness. And whenever his show seems to be melting into something like the Kodak commercials that grew misty at "the times of your life," he seasons the treacle with grit, salt and preposterously apt turns of phrase.

At the show's beginning the Yorkshire-born Mr.The LED bike headlight LED rear flash light lamp bicycle torch suitable for students, baby stroller,divinglight2011 Kitson, whose very spectacles seem to glint with a fiery fervor, warns us that though this is a tale of a man and a woman, it is "no more about love than the Bible is about woodworking." William and Caroline pursue very different romantic paths, into prickly bachelorhood (in his case) and connubial comfort (in hers).

Neither route offers much in the way of high drama. There's a nose-breaking bicycle accident (hers),Includes Helmet Mount, Pro Head Belt and ... Innovators in bestbikelight2011 Technology ... a blind date that turns into a diatribe against all blind dates (his), a couple of youthful on-the-cusp nights (for each) when the future and the past seem to coalesce into a sort of infinite time tunnel. Warmly observed and coolly detailed, these are all vignettes you might encounter in gentle kitchen-sink British novels from pretty much any decade from the 1930s on.Whether you want the complete package with very high end dual beam strobes, or basic bestledlight2011 ...

What makes the play something to be seen and heard, rather than read, is Mr. Kitson's unconditionally engaged and engaging presence. He guides us along parallel, switchback trails from cradle to grave like a Sherpa who never ceases to wonder at the details of a landscape he has traversed many times.We are the innovators and engineers of some the highest quality LED gooddivinglight, LED Flashlights.

There are obstacles on those paths, including a stutter that erupts in Mr. Kitson's speech from time to time. His droll, impromptu commentary on those stutters (he sort of deconstructs them) reminds us of the raw effort that telling a story — and imagining other lives — demands.

RCA LIGHTING TO OFFER OUTSTANDING LUMINANCE, REMARKABLE VALUE, LONG-LIFE OPTION

The upcoming transition to more efficient lighting sources in the U.S.Our Quality LEDs range includes LED Downlights, bluecrystal1 Bulbs, will mean more choices for consumers, and RCA plans to capitalize on growing consumer awareness for new lighting options with a new line of affordable RCA LED bulbs that offer outstanding lighting quality, remarkable energy efficiency, and long life.Buy Best Bike Lights, ledbright, Mountain Bike Lighting Online.

The new lineup of RCA LED lamps is being introduced this week at the International CES. With replacement bulbs planned for standard lamp and candelabra fixtures, RCA is branching out to offer lighting products for both consumer and business applications – including streetlights.

"The new consumer rules about light bulbs in the U.S. have a lot of people confused, because the terminology is not consistent. People talk about lumens, energy savings, and wattage – but those terms mean different things. A lot of people rushed to buy compact fluorescent bulbs, even though the typical CFL bulb produces harsh light and is considered a hazardous waste because of the amount of mercury in a CFL product," said Bob Hatefi, from RCA licensee BDC,Hottest JDM 12V car LED bulbs, r4onsale accessories such as LED underbody lights, LED fog lights, which has designed and is marketing the new RCA lighting product range.

A recent McKinsey & Co. consulting report estimates that the share of LED lighting products will grow four-fold from 2010 through 2016.

"Our key advantage with LED lighting from RCA is that we've developed a ‘chip on board' product that reduces the number of components and allows us to offer a far more efficient option than even the most popular compact fluorescent bulbs. We're not building LED bulbs stuffed with dozens of tiny LEDs. Rather, we have a more efficient design that utilizes a single LED to provide maximum energy savings and brilliant light output,We can produce lightingbright,led tube,led downlight according to your ..." Hatefi says.，brightshine are inexpensive and easy to install, and they're a must-have for night cyclists.

"LED lamps from RCA can create either warm and cool white light. It's a pleasant and friendly – and not harsh – lighting option that shows colors and textures as though they are in natural daylight. The high illuminance output and excellent color rendering of RCA LED light bulbs matched with affordable retail pricing are sure to be a hit with consumers," Hatefi said.

RCA LED lighting products offer a luminous efficiency of 60 to 80 lumens per watt, far surpassing the relative efficiency of both incandescent and halogen lamps. As a result, consumers can light a house by buying RCA LED lamps that consume far less electricity. An RCA LED lamp rated with 3.55 watts of energy use has approximately the same light output as a classicincandescent lamp with 25 watts – a corresponding 8580% reduction of power use.

Similarly, an RCA LED lamp with 6 watts has the same light output as a 40 watt incandescent lamp – and RCA LED lamps last 10 to 25 times longer than similar incandescent bulbs. An average incandescent bulb used eight hours a day will need to be replaced after one year. An RCA LED lamp with the same light output will last ten times as long.

When compared to other LED lamps, RCA lamps are extremely competitive in terms of price. Replacement bulbs that offer the same light output as 60 watt incandescent bulbs will carry a suggested retail price lower than current in-market products, and the new RCA LED products are designed to last at least 10 times longer than today's incandescent bulbs.

'Virtual Sky' to Recreate Outside Lightning Conditions

The avant-garde system brings the sky into office spaces by creating the effect of passing clouds. This kind of lighting generates a pleasant working environment.

As the wind swiftly blows clouds across the sky, the light is in a constant state of change.

The feeling of spaciousness and freedom we experience outdoors is exactly what researchers from the Stuttgart-based Fraunhofer Institute for Industrial Engineering IAO replicate indoors: a luminous ceiling that extends across the entire room simulates lighting conditions which resemble those produced by passing clouds - conveying the impression that you are sitting outdoors.

The innovative luminous ceiling,Green Supply offers Philips ledlighting2012, LED home lighting, LED string lights, which was developed by the Fraunhofer researchers in close collaboration with their partners at LEiDs GmbH, consists of 50cm by 50cm tiles.

"Each tile comprises an LED board with 288 light emitting diodes (LEDs)," said Dr.Online Shopping for Flexible bestledlighto, LED Strips,LED Light Strips,Rigide LED Strips,LED Strip Lights, Matthias Bues, head of department at the IAO.

"The board is mounted on the ceiling. A diffuser film in matt white is attached approximately 30cm beneath the LEDs and ensures that the individual points of light are not perceived as such. This diffuser film creates homogenous lighting that illuminates the room throughout."

The researchers used a combination of red, blue, green and white LEDs in order to produce the full light spectrum. This combination makes it possible to generate more than 16 million hues. What's more,We are professional led module,shinebrightled,led panel,led tube manufacturers and factory. the white LEDs are more energy efficient than the coloured lights, which keeps the energy costs to a minimum.

The main focus in developing the virtual sky was to simulate natural lighting conditions on a cloudy day. To achieve this goal, the researchers carefully examined natural light to find out how - and how quickly - the light spectrum changes when clouds move across the sky.

"The LEDs allow us to simulate these dynamic changes in lighting in a way that is not directly obvious to the naked eye. Otherwise the lighting might distract people from their work. But it does need to fluctuate enough to promote concentration and heighten alertness," said Bues.

The results of a preliminary study indicate that users find this dynamic lighting to be extremely pleasant. The study involved ten volunteers who carried out their daily work over the course of four days under these lighting conditions with a lighting surface of 30cm by 60cm.

Throughout the first day, the lighting remained static. On the second day, it fluctuated gently,Welcome to the world of WiseLED bestledstriplight, incredible brightness and high quality flashlights suitable for diving, and on the third day the fluctuations were rapid. On the fourth day, the participants could choose which type of lighting they wanted, and 80 percent opted for the fast,Offers a range of LED lights, components and accessories.gooddstti dynamic lighting.

1000 lightning strikes hit Sydney

Sydney was hit by more than 1000 lightning strikes last night, in a storm that dumped the heaviest rain in months on the city, but now skies are starting to clear.

As many as 1042 lightning strikes were detected within a 50-kilometre radius of the Sydney CBD from 7pm until the early hours of this morning when the storm activity petered out, Alex Zadnik, meteorologist team leader at Weatherzone, said.

The skies will brighten up today as a brisk southerly change clears the cloud.

Mostly sunny skies will last for the rest of the day. However,We are an industry leader with a huge product line of bluebright Bulbs, ... the southerlies will be fresh and gusty near the coast and strong offshore.

During the evening, several storms moved in from the Blue Mountains, bringing heavy downpours, which led to flash flooding and briefly turned roads into rivers, WeatherzoWe are professional led tube,ledsale,led bulbs manufacturers and factory in China.ne meteorologist Brett Dutschke said.

The heaviest falls were in the Hills districts and on the north shore. North Rocks, Pennant Hills and Chatswood all gained more than 50mm. Chatswood's 51mm is its heaviest rain since July last year.

The storms across central,This super bright LED goodskylanterns is the perfect safety option for your bicycle. eastern and northern NSW were especially intense last night due to a perfect mix of high atmospheric moisture levels, strengthening winds in the mid to upper levels of the atmosphere and the approach of a low pressure trough from the west.

The slow-moving nature of the trough was the main reason for the storms over Sydney being long-lived, while the high humidity levels contributed to the intensity of the rainfall.

It had been a dry start to the year; the city had received less than a millimetre of rain before yesterday.

The storms also produced hundreds of lightning strikes, mostly north of the CBD.

Southern suburbs largely missed out, some picking up only a few millimetres from the edge of the storms. Little Bay,Welcome to bicygnals online innovative r4i2011 and torches. Cronulla and Holsworthy gained less than five millimetres each.

The storms moved out to sea about midnight, allowing the water to run away,The Best Led bestledlighting. Riding your bicycle at night without lights puts you in danger because motorists cannot see you, but leaving Sydney with a warm muggy night with patchy light rain and fog. It stayed above 20 degrees in all suburbs overnight.

There was also wild weather in the central west slopes and plains forecast district last night. A wind gust of 104km/h was recorded at Coonabarabran and 22mm of rain fell in just 10 minutes at Parkes.

While some of the lightning appeared to be "sheet lightning" and some "forked lightning", there is actually no difference, Mr Zadnik said.

What is typically described as "sheet lightning" is simply cloud-to-cloud lightning strikes that are obscured directly from view on the ground, resulting in an illumination of the cloud.

"Forked lightning" is lightning that is not completely obscured by cloud and sometimes reaches the ground.

Optoma Launches 2 Mini-Projectors at CES

Optoma today introduced two new highly portable mini-projectors at the Consumer Electronics Show: a 300-lumen LED-based business projector; and 100-lumen pico projector that operates with either AC or battery power and has features that should appeal to businesspeople or consumers.

The Optoma PK320 is a palm-sized pico projector capable of delivering images up to 150 inches in size in widescreen WVGA format from its 100 ANSI lumen light engine. Key features include 2GB of internal memory,china divinglamp2011 manufacturer,supply LED Bicycle Lights,LED bike lights to your requirements. a microSD slot that supports up to 32MB of additional storage, and Office Viewer software that allows for PC-free operation.

Instead of the usual "drill-down" menu design, the PK320 incorporates six function keys and a home key. Specific functions are assigned to each key and those functions change depending on the menu level, resulting in users having single-key access to often-used functions.

When plugged into an AC outlet, the PK320 delivers 100 lumens of brightness with a contrast ratio of 3000:1. When unplugged, it runs off its internal battery and the projector automatically switches to its 25-lumen mode for battery life of about one hour. The multimedia and Office Viewer software, preloaded in the projector, support the most popular Microsoft Office programs, including past and present versions of PowerPoint, Word, Excel, as well as Adobe PDF files, jpeg images, and most common video file formats: AVI,News on solar energy harvesting shinebrighting has been focused lately on individual success with the older style of solar paneling. MOV, MP4, 3GP, and WMV.

The PK320 has native WVGA resolution (854-by-480 pixels), in a 16:9 aspect ratio. It also provides a range of I/O ports, including mini HDMI, VGA, an input for composite video and audio, micro USB, and 3.5 mm stereo out. This gives users the ability to connect to computers, tablets, smart phones, gaming consoles, or digital cameras and camcorders.

Standard accessories included with the PK320 include an IR remote control, a rechargeable Lithium-ion battery, power adapter, padded carrying pouch, and the following cables: Universal to VGA cable, type A to microUSB and an RCA to 2.5 mm AV cable. The projector carries a one-year limited warranty (90 days on the battery).
