Full Spectrum Daylight Bulbs – Simply Light Years Ahead!

Sunlight is a vital nutrient, which regulates the activity of the hypothalamus gland that secretes seratonin, controlling our moods, biorythms, sleep patterns, body temperature, digestion and sex drive.
In addition, the photochemical action of sunlight on our skin activates the production of vital Vitamin D essential for growth and maturation of cells, the maintenance of the bones and a healthy immune system.

Most of us don’t think of ourselves as light deficient yet research shows that even on an average overcast day our seratonin levels fall and we can become depressed, moody, irritable, gain weight from overeating, develop carbohydrate cravings, become insomniac or sleep excessively, suffer from lethargy and fatigue, lose our sex drive, lose concentration easily or just feel extra stressed.

Indeed most of us tend to be confined indoors in homes or at work – artificially lit with narrow spectrum, low intensity light for as much of 90% of the day! A season-less perpetual twilight existence indoors day in- day out, its no wonder we get a yearning for natural sunlight and we instinctively pine for sunny holidays. Longer term, the effects of this so called ‘light pollution’ puts stress on the body and eyes and may even compromise the body’s immune system.

Switch on the lights and the Biobulb Full Spectrum Electronic Daylight Bulbs safely and gently bathe you in the glow of mood enhancing, life giving ambient simulated daylight replacing those lost hours of daylight and helping to alleviate a whole range of conditions from anxiety, sleep problems, fatigue and low energy levels, depression, eyestrain, headaches, jet lag, libido, hyperactivity, irritability and give us drive, vitality, mental agility, alertness and energy to face the challenges of the day. Research also shows full spectrum daylight can even help to lower blood pressure and cholesterol levels as well as significantly increase cardiac output.

On at night – the light emitted from the bulbs appears in the room as if illuminated by natural daylight. But by day the light emitted from the bulbs is so close to natural daylight that it’s light merges into the natural daylight of the room – making the room naturally brighter, gently stimulating the senses – yet most people would be blissfully unaware that the lights were switched on at all! That’s the magic of Biobulb Full Spectrum Electronic Daylight Bulbs

And apart from the profoundly positive influence on mind, body and soul Biobulb Full Spectrum Electronic Daylight Bulbs are also proven to be the kindest light for the eyes – excellent for reading and writing as well as intricate crafts including needlework, drawing, painting, sewing and so on.

What’s This Digital Television Thing All About?

What is DTV?

Digital television is the next generation of video broadcast technology. The old system, called analog television, was created in the 1950s. DTV was created for the 21st Century by a working group of programmers, broadcasters and engineers, so that consumers will get the best product. The same way computers scan photos into data files (literally turning your vacation pictures into a series of 1s and 0s); DTV changes the film and video into digital images (those same 1s and 0s) and transmits them.

Analog still works, so why switch?

They used to say, “If it ain’t broke, don’t fix it,” but 8-track tapes were replaced by cassette tapes, which were replaced by CDs and so on. New technology does the same thing, but does it better. By changing the way TV signals are broadcast, the signals use less bandwidth, meaning more programming can be sent out over the airwaves. According to the FCC website, “That means better quality, more choices, and more control over your television.”

Using less bandwidth also means parts of the broadcast spectrum will no longer be needed by the TV industry. This spectrum is limited, like a series of pipes; there are many, but only so many. DTV means television needs fewer pipes. The others can be reassigned to public safety–police, fire and paramedic services–or wireless phone service providers or other uses.

When and how did the switch happen?

The Federal Communications Commission (FCC) started setting up the switch-over in 1996. Starting March 1, 2007, all televisions built in or imported to the US must have a digital tuner as well as an analog tuner. Many stations launched digital broadcasting in addition to analog broadcasts in late 2008 or ’09. On June 12, 2009, all major TV stations ceased sending out analog signals. A few small, local TV stations will continue using analog.

Consumers who purchased TVs built March 2007 or after didn’t need to do anything; they were built switchover-ready. In fact, the switchover went smoothly, most people probably didn’t even notice it was happening. Those with older sets can buy a new TV or a converter than translates digital back to analog signals.

Analog-only TV sets built before March 2007 may still be available for sale; if so, retailers must to post a notice clearly stating which sets are analog-only.

Will consumers need a special antenna to get digital television programs?

Consumers who currently use an antenna, either on-the-set ‘rabbit ears’ or a roof-mounted antenna, should receive digital signals as well as they received analog signals.

Is this related to high-definition television?

No, HDTV is a separate issue. HDTV audio and video signals were always digital, this action means that regular TV (sometimes called ‘enhanced’ television or ETV) are is also now digital. Consumers do not have to buy an HDTV to see digital-TV programming. Broadcasting programs in enhanced and high-def formats is called ‘multi-casting,’ which will be one of the big advantages of the digital switch.

Other useful facts:

Consumers who decide to buy a new television don’t have to send their old set to a landfill; many communities have recycling programs.

Cable systems are not required to switch to digital; many cable companies offer digital and high-definition program packages as well as analog. Some may eventually choose to switch to all-digital programming. The FCC’s DTV rules apply only to broadcasters–those who use the public airwaves to deliver programming to consumers.

Parental controls (like the V-chip) will work as well with digital signals as they have worked with analog.

Like all consumer electronics, televisions have changed a lot over the past fifty years. With few exceptions, these have been changes for the better. Digital television is simply the newest member of that list.

White Space – The Debate Over Free Wireless Spectrum

With the announcement of the website FreetheAirWaves.com by Google in order to support the white space campaign, the debate over the “white space” issue has reached a new level.

In terms of Google white space is the space of unused frequencies in the range traditionally defined for TV channels. Google and some other leading companies wants to transform this range from licensed, like TV where specific frequencies are granted exclusively to a specific channel, to unlicensed, like Wi-Fi where anyone can use it. They call it “Wi-Fi on steroids.” The spectrum would enable longer-range, higher data rate, and faster wireless connectivity for all types of gadgets.

Along with Google other technology companies like Intel, Dell, HP, Microsoft, and Phillips Electronics are united in a coalition called the Wireless Innovation Alliance. They have been lobbying the FCC (Federal Communications Commission) to open up this spectrum for unlicensed use after the digital TV transition early next year.

The National Association of Broadcasters (NAB) and phone companies are entirely against this initiative. The Television and phone companies want exclusive rights to various frequencies. These spectrum that sit idle between TV channels as buffers, in order to ensure that TV signals don’t interfere with each other, could be used to provide broadband wireless services. But according to the broadcasters, these channels will cause interference with their TV signals and eventually resulting in major problems for people watching TV.

The FCC has done a number of testing of the spectrum to see if wireless devices will interfere with each other. The results of the tests have been mixed. But Google has make out a solution for this problem. Now it is proposing new rules to designate specific frequencies for TVs, wireless microphones, and for other devices, and then another spectrum for wireless Internet access.

Next month the FCC is likely to release a report based on the test results. It will finally vote on whether to open the spectrum in the next few months. This issue has become as much of a political debate as it has a technical one. The National Association of Broadcasters is pointing that interference can’t be avoided, based on tests as evidence. While Google and other technology companies argue that these are simply proof of concept devices and are not even like the prototypes that could be used in commercial products.

NAB and other Wireless companies, such as Verizon are opposing the use of white spaces because they have their own business motivations for opposing the use of white spaces. The afraid of interference might be a concern for the NAB but the more prominent reason for opposing this concept is that its members are reluctant to give up control of airwaves, which they believes are theirs.

Along with other technology companies, Google has its own motivations and interests to consider. Google can make more from advertising if more wireless spectrum and broadband services are available. Other companies like Intel, Microsoft, and Motorola would also be benefited as they could sell more products and services to consumers who use this unlicensed spectrum.
