Cree has entered the LED replacement bulb market with its own name brand bulb. Cree is offering both a 40W and 60W version of the light; My review here covers just the 60W version. Here are the specs: First, the cosmetics: It’s similar in looks to a 60W incandescent bulb. The incandescent weighs 28.3 grams (1 oz) and the Cree weighs 113.4g? (4 oz.), so it’s a little heavier,Tubos LED, but still quite light. It dims quite nicely, with absolutely no flicker at the bottom end. I hunted around at the low end of the dimming range, right where the light turns off, but couldn’t make it flicker or flash. I tried dimming with both a Lutron Maestro dimmer and a garden-variety cheap triac dimmer, but the light output was smooth at all times. Very nice. Along with flicker, audible noise is a bugbear for many LED bulbs. How does the Cree stack up? I had to get my ear within 12 inches to hear any hum at all. Aha, I thought, there must be some serious potting compound inside the bulb to damp out the high-frequency inductor noise. (Spoiler: I was seriously wrong here.) The color temperature of 2700K ?– a standard color temperature for LED replacement bulbs –is warm and pleasant. Cree does offer the bulb in a much cooler 5000K temperature and prices it a bit higher, most likely because at the cooler temperatures the bulb is more efficient at producing light. The 5000K bulb requires only 9W to produce 800 lumens compared to the 9.5W of the 2700K tested. In addition, people tend to think of the cooler temperature light as being inherently brighter because of the stark contrast with shadows. However, to live with on a daily basis, stick with the 2700K version. At this point, I’m through with a consumer review for the Cree bulb. The light is warm and pleasant, the dimming excellent, there is no annoying noise, and it costs less than $13. Go buy one – it’s a great value and supplants my previously favorite LED replacement bulb, the Best Buy Insignia. But what lies beneath? What design decisions did Cree, one of the Big Three LED component manufacturers, make when it put on its hat as a consumer product manufacturer? To do a tear down, the first challenge is to remove the silicone-covered glass bulb cover. I used my favorite method (told to me by Peter Di Maso of Texas Instruments) for removing LED bulb covers: Soak it in the oven at 200F for 20 minutes and then twist the cover off while wearing thick leather gloves. Worked like a charm. Even better, it was still possible to operate the light and probe for some voltages. At full power, the voltage across the LEDs was 220Vdc;? When dimmed to where the light cut out it was 207 Vdc.? 220V is a pretty high voltage for powering an LED light. What’s up with that? Let’s take a look at the LED array. As you can see, the LEDs are mounted on a column that sticks up through the center of the light. (These are white LEDs, that is, blue LEDs covered with a white-light-emitting phosphor.) There are a total of 20 LEDs mounted in ten groups of two on a metal core pc board that’s scored between each two LEDs and then bent into a ten-sided shaped that slips over the column. You can also see that each yellow-colored LED has four bumps in it. These bumps are probably LED emitters, so each individual LED component is actually a tiny matrix of four LED emitters that share the same phosphor coating. So that makes for [CORRECTION] 80 LEDs in series. (For more information about the LED used and how careful selection can reduce the BOM costs, see: ) There was no isolation transformer, indicating that the (which continues the trend we saw in the Insignia bulb.) Non-isolated LED drivers drop the parts count significantly and shrink the space needed for power management, dimming, and power factor correction (PFC). As you can see from the photo below of the front and back pc board photos, this bulb has amazingly few components. It also has excellent PFC: I measured .98 PF with a Kill-o-Watt meter. Sure enough, the 8-pin IC is a transition mode power factor corrector, driving a three terminal , also by ST.? Apparently, the PFC pre-regulator operates as the power management for the entire drive circuit. I was impressed that the circuit was not potted, which is very unusual, especially in such a quiet bulb. In addition, rather than relying on kludge-y hand-soldered connections, the bulb uses a couple of clips to transfer the power from the center of the LED column to the LED array on the outside of the column. (See the photo of the LEDs on the column above; The clips are on the left and right side of the column.) The whole assembly almost snaps together, making it easily and reliably assembled. Also of note: It’s made assembled in the USA. UPDATE: For more info on Cree’s design decisions read: .

We all know that Republicans and Democrats tend to disagree when it comes to taxes, foreign policy, and Chick-fil-A, but a new study hopes to add another item to that contentious list: light bulbs. Researchers at the University of Pennsylvania that as environmentalism has become more politicized and partisan, personal politics is now deciding whether or not consumers forgo cleaner, cheaper light bulbs even when they know the benefits. If environmentalists dont find a nonpartisan way of framing the issue, incandescent light bulbs might become another thing that red America "clings" to, albeit more uncomfortably than to Bibles and guns. The UPenn study safely establishes what we all already know: Attitudes towards the environment are intrinsically political. The sampled 657 individuals to find out if their opinions on greener, more efficient light bulbs correlated significantly with their political identifications (they did). A smaller group of 210 were briefed on the benefits of compact fluorescent light bulbs (CFLs), which last drastically longer than incandescent light bulbs and cut energy consumption by 75%. Armed with that information, volunteers were asked to choose between regular incandescent light bulbs and slightly more expensive CFLs, identified by a sticker touting their environmental bona fides. Unsurprisingly, Republican volunteers opted for the cheaper, incandescent bulb, while Democrats splurged for the greener, more efficient CFL. Both sets of consumers knew that CFLs actually save money over time, but volunteers still chose largely along political lines. To Democrats, environmentally-friendly light bulbs, which last about 9,000 hours longer than traditional bulbs, are a good in and of themselves, a sign of our inevitable progress towards a greener, more rational society. To Republicans on the other hand, "green" light bulbs are seen as just another way liberal tastes and preferences are being stuffed down their throats with a from Uncle Sam. This, for environmental advocates, has always been the elephant in the room. Though we spend a lot of time and energy identifying Congress and corporations as the primary obstacles against smarter, greener policies, the truth is that they are only part of the problem. As far as environmentalism is concerned, we have found the enemy, and it is us. Our party identifications guide not only our policy preferences, but also what kind of music we listen to, what kind of books we read, and, apparently, how we light our homes. Other have shown that Democrats and Republicans even drink different beers. Heineken, for example, is a solidly Democratic brew, while Miller and Coors Light fare better with Republicans. We like different cars, makeup products, and car insurance (Democrats Progressive, zing!). This might all seem trivial. Of course, it doesnt really matter if red and blue consumers drink different cheap beer. But light bulbs are more than just a cultural signifier. The seepage of our extremely partisan political culture into our consumer choices becomes worrying when it affects how we react to the environment, which was a bipartisan issue not too long ago. After all, the modern conservation movement began under the Theodore Roosevelt administration, which quadrupled national parks, and Richard Nixon the Environmental Protection Agency. However, over the past 40 years both parties have turned the environment into a partisan cultural and political issue the right by increasingly associating itself solely with business interests, and the left by articulating green arguments in a condescending and counter-cultural tone. That work now needs to be undone. Someone's politics should not affect whether or not they help protect the environment and save money in the long term by buying a 21st century light bulb. Partisan politics might (occasionally) work in Washington, where all progress boils down to the matter of passing a bill, but to get red-state America to buy a greener light bulb, we need to remove environmentalism from partisanship altogether. If we dont, and continue to rely solely on the government to improve society, dont be surprised if Republican voters buy these light bulbs kicking and screaming, protest outside CFL factories like they do abortion clinics,Motion sensor LED, and vote dozens of non-binding resolutions through the House "rolling back" Obama-bulbs. Currently, the left owns the environmental movement, a partisan achievement that does nothing more than let us feel good about ourselves. A new way of talking about this is needed. Lets start with light bulbs.

A mostly instrumental solo studio project of Misha Mansoor. Bulb is also a moniker of Misha's and is named after an old and now defunct band he was once a member of,tubo led. There are plans to one day take Bulb on tour as a 'convertable band', meaning that the only consistent members would be Misha and vocalist Thomas Murphy (who also plays bass in Periphery). The rest of the members would be location-dependant.

The phaseout of traditional 100-watt incandescent light bulbs last January—a move to meet new federal efficiency standards—struck panic in the hearts of some consumers. Home Depot () reported an up-to 20 percent spike in sales of 100-watt bulbs for 2011 as people rushed to stockpile for the future. At least one Ohio woman made sure to squirrel away enough bulbs to last .?A month from now, on , traditional incandescent 75-watt bulbs also will go the way of the Dodo, as the second stage of the phaseout goes into effect. This time around, however, shoppers seem more relaxed. “Last year we saw some consumers buying up product, but that’s really slowed down,” says Bill Hamilton, president of light bulb merchandising at Home Depot. “Customers are beginning to embrace the new technology.” Hamilton says the initial rush to hoard traditional incandescent bulbs may have resulted from a reluctance to learn about alternatives. “We’ve done some focus groups and customers have basically told us, ‘I haven’t had to think about light bulbs or lighting for the last 100 years—Don’t make me learn about it now,’” he says. These days, customers have gotten over the hump and discovered numerous alternatives, including LEDs, compact fluorescents, and even incandescent bulbs that meet the federal requirement of being at least 25 percent more efficient. It also doesn’t hurt that the retail price of energy-efficient bulbs has dropped by more than half over the past year, as companies perfected their technology and rolled out mass production, says Hamilton. Not everyone has embraced the government’s energy-efficiency standards, which passed in 2007. Representative Michelle Bachman (R-Minn.), who once , “I think Thomas Edison did a pretty patriotic thing for this country by inventing the light bulb,”?has sponsored the to repeal the phaseout of incandescent bulbs. And in July, House Republicans adopted a measure to halt the light bulb-efficiency law. “People are sick of the government treading where it just doesn’t belong,” Representative Michael Burgess, a Texas Republican who sponsored the light bulb amendment that was added to a broader energy-spending bill. The House measure is, in fact, an extension of a rider placed on the light bulb law in December 2011, prohibiting the U.S. Department of Energy from using any funds to enforce the federal light bulb law. This means that, although such lighting manufacturers as General Electric () and Royal Philips Electronics () stopped making traditional 100-watt bulbs, there’s no guarantee that other companies would do the same.?(The efficiency standards prohibit only the manufacturing and and distribution of the light bulbs, not their sale.)?“Some in Congress are willing to put U.S. jobs at risk for political positioning,” Joseph Higbee, a spokesman for the National Electrical Manufacturers Association (NEMA), told my colleagues at . “This is an example of a few politicizing light bulbs at the risk of American workers and the economy.” Higbee says manufacturers are, in fact, supporting the efficiency legislation, which NEMA estimates could mean? worth of national energy savings per year. Companies such as GE and Philips, he says, have invested millions of dollars in developing alternative products, and they resent being left in limbo because of political infighting in Washington. Higbee expects the rider preventing enforcement of light bulb efficiency laws will be dropped in 2013, and that the phaseout will continue into 2014, when the traditional 60-watt and 40-watt bulbs are scheduled to be discontinued. The biggest shift for customers,mr16 led, meanwhile, will be learning the new light bulb lingo. Instead of thinking in “watts,” which measure the amount of power going into a bulb, they henceforth must think in “lumens,” which measure the amount of light produced. Explains Higbee: “A more efficient bulb will require fewer watts to produce the same amount of lumens as a less-efficient bulb.” If this doesn’t make sense, don’t worry. Home Depot has spent plenty of time and money over the past year training employees to help customers find what they need. “Articulating what’s best—what the advantages are in terms of energy, light output, quality, and color—that’s really our biggest weapon,” says Hamilton. For those who just don’t want to give up their trusty Edison bulbs, there’s always EBay (). Hurry, while supplies last.

Hello everyone, here's another post in my series: From RAW to Final, where I show you how I take an image all the way from RAW to its finished, final, look. Today, I would like to share an image I took last week as I was traveling and photographing in the Canadian Prairies. This image, entitled "Prairie Train Cars' was photographed near Calgary, Alberta. Image Details: Cambo WDS camera with 35mm Lens. Phase One Digital Back. Panorama from 2 images, 300 and 538 second exposure time. Merged in . I was on a 5 day trip, starting and ending in Calgary. We spend between 12 - 15 hours each day travelling and photographing the Prairie landscape and communities such as Lethbridge, Oyen, Drumheller etc... The focus of this photography tour was to discover, and photograph, the wooden grain elevators and grainaries dotting the landscape. We found these train cars, apparently parked in this location for undetermined amounts of time, near the grain elevator of Herronton. When we arrived, our attention shifted away from the grain elevator (we also photographed it, of course). The clouds and weather conditions were simply amazing,lampara, I setup my Cambo WDS camera so as to take 2 images that I planned to merge to a panorama. Using panoramic images, not only do I get images with higher resolution, but I also get a wider angle of view without having to buy a wider angle lens. On my Cambo camera, the 35mm lens I was using is very wide on its own already, but merging 2 images gave me an even wider perspective. While working on my composition, I wanted to make sure to place the 'Canada' train car close to the middle so that it would serve as the focal point. The wideangle perspective allowed me to include generous amounts of sky and negative space around the train cars. The foreground was simple gras, which also helped draw the viewers eye into the scene. STEP 1: So let's get started and first take a look at my 2 RAW files: Note that I have converted the original RAW files to DNG format. This allows my panoramic program of choice, Autopano Pro, to read my RAW files coming from my Phase One Digital Back. If you're shooting with a DSLR you won't need this step as Autopano can read most RAW file format from major manufacturers. Also note that I made a 'mistake' as I did not use the same exposure time for both images. Because if this, I will run into some merging troubles later on, and you'll see how I addressed it. In a perfect world, you want to make sure you'll use the same exposure time for all images you plan to merge into a panorama. STEP 2: Merge images into a panorama using Autopano Pro Software: In the image above, you can see that cropping to a 2:1 panoramic aspect ratio will result in only a small loss of original resolution. In my workflow, I usually crop in Autopano Software, and then export the image for editing in Photoshop later. STEP 3: Editing in Adobe Photoshop and Nik Silver Efex Pro Software: You can see that I 'only' needed 5 layers to get this edit done. The biggest adjustment, if you want to call it that, is that I split the sky and clouds in half and then mirrored it and put it back into the image. I also use 2 other essential techniques in my Photoshop workflow, namely a Dodge and Burn Layer, and a selective sharpening layer using the Hi-Pass filter. I decided to record a video showcasing my entire workfow for this image. I think this will go a long way to explain what I was doing. The video is uploaded and posted on Vimeo. Take a look: from on . Please be so kind and leave me some feedback on the video. Do you want to see more like this? Do you have any additional questions? Anything I missed that would improve this effort? Thank you for reading/watching this post. More tk...

Futuristic High-Speed Tube Travel Could Take You From New York to Los Angeles in 45 MinutesBy , a high-speed transportation tube that uses magnetic levitation. The ETT can travel at speeds of up to 4,NEWLIFE LED NEWS,000 miles per hour, and each tube seats a maximum of six people and comes with a baggage compartment. How does it go so fast? It's airless and frictionless and could have you from New York to Los Angeles in 45 minutes, as opposed to the nearly five hours a direct flight would take. It could even have you depart from New York and be in Beijing in two hours. The tubes would be set up like freeways to prevent crowding and traffic congestion problems. Plus, ET3 claims that passengers need not worry about feeling discomfort while traveling at such high speeds. The high velocity at which the tubes move is equal to 1G of force at top speed, which is similar to the force felt by someone traveling in a car on the freeway. , the founder and CEO of ET3, says that he got the idea for the tube transport system when he visited China back in the 1980s. When and if the tubes make their debut in the next decade, they will initially be used to transport cargo, not people. [Related: ] Like us on , and follow "Trending Now" on Twitter: and .

Bulb, abbreviated B, is a setting on an adjustable camera that allows for long exposure times under the direct control of the photographer. With this setting, the simply stays open as long as the shutter release button remains depressed. An alternative setting common on film cameras is Time, abbreviated T, where the button is pressed once to open the shutter and again to close it. History [] The term bulb is a reference to old-style pneumatically actuated shutters; squeezing an air bulb would open the shutter and releasing the bulb would close it. According to the Focal Encyclopedia of Photography: It is not clear when the term actually originated. The first industrial produced leaf shutters from in Germany in 1890 had two settings. 'M' for Moment exposure and 'Z' for Zeit (Engl.: Time) exposure. The M-setting enabled the adjustable fractions of a second. With the Z-setting the shutter opened when pressed and closed when it was triggered again. Around 1894 the third setting 'B' for Beliebig (Engl.: any time) was added for the shutter of in . The B-setting enabled his shutter to stay opened as long as the release was pressed. in Rochester overtook these settings for their popular Unicum shutters in 1898. With the worldwide success of the Optimo shutter of in 1909, most of the other shutter manufacturers in the world overtook the (now international) settings T for Time, I for Instantaneous. The B setting was kept for the familiar bulb behavior that could be duplicated with a cable release in the English speaking world and for Beliebig in Germany. Use [] The bulb setting is used on some cameras, including some point-and-shoot cameras, to obtain shutter speeds slower than the maximum offered by the camera otherwise. Because of the risk of camera movement,MR11 LED, the camera is most often mounted on a for the duration of the exposure. While it's generally possible to use the shutter release button on the camera itself, a cable release or electronic remote is often used to further eliminate the risk of shaking the camera during the long exposure. The cable releases generally include a locking feature to eliminate the need to keep the button or plunger depressed during extremely long exposures. The bulb setting is useful for the following types of photographic subjects: On modern cameras [] On some modern cameras, bulb is a mode available as an option on the menu only, if possible at all. On others, including many cameras, bulb is typically available from the mode and—rarely—also from mode. When set to bulb, generally on the "M" or manual setting of the camera, the will stay open as long as the shutter release button (or shutter release cable or remote) remains depressed. Some mid-level or such as the SP-560UZ have a 'limited' bulb setting, allowing time exposures up to 8 minutes and at an of 200 ISO and lower. In 2012, introduced a new form of bulb mode with their "Live Bulb" (without toggle) and "Live Time" (with toggle) settings in their digital camera, where the viewfinder and display gets updated 'during' the exposure in order to allow the photographer to inspect the exposure while it "develops". The display refresh rate for this mode can be configured between 0.5 s and 60 s. Some specialized cameras use other . Gallery []References []
