Lighting up landscaping

"We have an outdoor lighting laboratory, he said. "It's an outdoor scene with a darkroom, a front entrance, a patio walkway, a fountain and a statue. In that room we have about 30 different light fixture options."

Techniques such as uplighting, cross lighting, grazing, silhouetting, spread lighting, and path lighting can all be developed to the homeowners' vision, Dodick explained.

"Any kind of scene you want to do..Solar antiquelamp is a kind of solar light which used for garden decoration and lighting,it is popular as it do not need wiring and Mains Power supported..when it comes to creativity, the sky is the limit," he said.

Professional lighting is an investment, but one that will last, Dodick said.

"It is possible to spend as much on lighting the exterior of your home as you spent lighting the interior," he said. "Most of our job quotes come in at $1,200 to $1,500."

If you have an existing 120-volt exterior receptacle, you can install lights on your own, he said, which may help cut down on costs.

"It really can enhance and expand your living space -- especially during the dark winter months," Dodick said. "Looking out on a beautifully lit landscape has a whole different feel than looking through a window and seeing nothing more than the darkness of night."

It in many ways defines you and your living style, making your house truly "a home," Dodick said.

"It most certainly enhances the beauty of your home whether inside or out and more than ever sets your home apart from the next,Energy efficient, eco-friendly lighting, contemporary outdoorlightss, LED light fixtures." he said.

Highlighting some focal points in your yard including tall trees, evergreens, shrubs,Get outdoor lighting, including popular patio lights and goodchandelier fixtures. perennials or ground cover completes the big picture and provides a beautiful portrait of your home both from the inside or outside of your home, Dodick said.

"It is possible to start small and add to your system annually by focusing on areas of your lawn and landscape that you want highlight and create a series of focal points over time," Dodick said.

Dodick said Wholesale Electric Supply is a supplier and they do not do installations. However, they are available to assist customers with a layout if they can bring in a scale drawing of their landscape.

It's also important to be familiar with your plants, shrubs, and trees and even how you expect them to mature in size down the road.

"We can show you several different scenarios that you can create outside," he said. "Just come on in."

Jim Bacon of Helping Hand Landscaping of Midland said solar lights are an affordable option.

"The technology is better now than when they first came on the market," Bacon said. "I have a set in my yard I bought for $1.99 a piece that are very bright and last about nine hours between sun charges."

Bacon offers a variety of landscaping services including installing lighting schemes. He said the choices are almost endless.

"It depends on what they want ... some lights are made with copper or brass finish, Bacon said. "These go for $5 to $10 a piece. Some low voltage lights are expensive, but once you get the transformer box you can add several lights to the system. Most boxes handle halogen or LED lights."

Bacon also explained that fiber optic lighting is gaining in popularity now especially with ponds and waterfalls.

"Basically you can get a solar light for $2 or a state of the art low voltage LED system for a few hundred dollars," he said. "Solar lights absorb light during the day and at night they come on. During the winter they only last part way through the night because there is less daylight and more dark time."

They can light up your life ... or not

Before you report a burned out street light, you must know the street light’s pole number. Without that number, your complaint will go nowhere.

A complaint that went nowhere has kept residents of Valleyview Avenue in Thornhill waiting more than six months to have their light replaced though they have all complained over and over to both regional district and BC Hydro.

While some wait time is understandable, a wait of more than six months is not only absurd but a hint something has gone awry.T5 fluorescent lamps are thinner, ledstreetlight, and offer a higher intensity of light output than T8 lamps .

Valleyview Avenue is a short street in Lower Thornhill. When its only light is out the entire street is dark. No other light exists on either side to compensate.

Here, courtesy of the Ministry of Transport’s Terrace office,We can produce crystal according to your requirements. are the steps to report a burned out street light in order to generate a work order with B.C. Hydro:

1. Get the pole number. This is embossed on a credit card-sized metal tag and consists of two rows of numbers, about 14 numbers on each row.

2. B.C. Hydro will then advise you who is responsible for that particular light -- regional district, municipality, or Ministry of Transport.

3. Next, contact the group responsible for the light and ask them to go online to BC Hydro’s Street Light Information Management System (SLIM) and file a repair request (using the pole number). Only the responsible party (and BC Hydro) can put the request into the program.

4. Once the repair request is entered into SLIM it will automatically generate a work order for BC Hydro.The bestfloorlamp are designed to run for 30 minutes before turning,”

For street lights in Thornhill, report your outed street light to regional district. They in turn will pass your information along to their Works and Services who will pass your information along to B.C. Hydro who will initiate a work order and set the wheels in motion.

If you do not supply the pole number, some enterprising staff member has to look up the pole number on a plan or maybe even drive out to look at the pole. (Don’t expect anyone to do that.) Your report will certainly be slowed, more likely sidelined into oblivion. Which is probably what happened in Valleyview’s case.

I’m betting no office informed Valleyview residents of the need to supply the pole number, guaranteeing they would wait forever to see the light.

In an email, BC Hydro offered this:

“1. While we do not have any set requirements as to how quickly a street light is repaired, we do have an expectation that once a work order is received the work is completed in 10 days. To be kept in mind is priority and emergency work takes immediate precedence over street lights.

The SLIM program received a phone call regarding this particular street light as opposed to an online request through the SLIM system. The agent entered the repair request immediately on 26 June 2012, which generated the repair work order overnight.

3. BC Hydro does take street light repair seriously hence the development of and investment in maintaining the SLIM program and the processes associated. Given the number of variations in street lighting around B.C. a single solution just isn’t possible, but we would welcome any feedback on the current set up as improvements are always welcome.”

The SLIM website allows the pole owner to check the pole’s repair history. SLIM showed no entry requesting repair of Valleyview’s only street light. So get that pole number before you report a light outage.

Utah Physicists Invent ‘Spintronic’ LED

University of Utah physicists invented a new “spintronic” organic light-emitting diode or OLED that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used in television and computer displays, lighting, traffic lights and numerous electronic devices.

“It’s a completely different technology,” says Z.Bellacor offers a large selection of bestledlight2011 for your yard or patio. Valy Vardeny, University of Utah distinguished professor of physics and senior author of a study of the new OLEDs in the July, 2012 issue of the journal Science. “These new organic LEDs can be brighter than regular organic LEDs.”

The Utah physicists made a prototype of the new kind of LED – known technically as a spin-polarized organic LED or spin OLED – that produces an orange color. But Vardeny expects it will be possible within two years to use the new technology to produce red and blue as well, and he eventually expects to make white spin OLEDs.

However, it could be five years before the new LEDs hit the market because right now, they operate at temperatures no warmer than about minus 28 degrees Fahrenheit, and must be improved so they can run at room temperature, Vardeny adds.

Vardeny developed the new kind of LED with Tho D. Nguyen, a research assistant professor of physics and first author of the study, and Eitan Ehrenfreund, a physicist at the Technion-Israel Institute of Technology in Haifa.

The study was funded by the U.S. National Science Foundation,Westinghouse's collection of bluecrystal1 fixtures includes wall lanterns, the U.S. Department of Energy, the Israel Science Foundation and U.S.-Israel Binational Science Foundation. The research was part of the University of Utah’s new Materials Research Science and Engineering Center, funded by the National Science Foundation and the Utah Science Technology and Research initiative.

The original kind of LEDs, introduced in the early 1960s, used a conventional semiconductor to generate colored light. Newer organic LEDs or OLEDs – with an organic polymer or “plastic” semiconductor to generate light – have become increasingly common in the last decade, particularly for displays in MP3 music players, cellular phones and digital cameras. OLEDs also are expected to be used increasingly for room lighting. Big-screen TVs with existing OLEDs will hit the market later this year.

The new kind of OLED invented by the Utah physicists also uses an organic semiconductor, but isn’t simply an electronic device that stores information based on the electrical charges of electrons. Instead,Shop for a wide variety of bestledlig lighting at ElementalLED. it is a “spintronic” device – meaning information also is stored using the “spins” of the electrons.

Invention of the new spin OLED was made possible by another device – an “organic spin valve” – the invention of which Vardeny and colleagues reported in the journal Nature in 2004.Gamma is a professional supplier of indoor and outdoor solarstreetlight solutions for office, The original spin-valve device could only regulate electrical current flow, but the researchers expected they eventually could modify it to also emit light, making the new organic spin valve a spin OLED.

Spin valves are electrical switches used in computers, TVs, cell phones and many other electrical devices. They are so named because they use a property of electrons called “spin” to transmit information. Spin is defined as the intrinsic angular momentum of a particle. Electron spins can have one of two possible directions, up or down. Up and down can correlate to the zeroes and ones in binary code.

Organic spin valves are comprised of three layers: an organic layer that acts as a semiconductor and is sandwiched between two metal electrodes that are ferromagnets. In the new spin OLED, one of the ferromagnet metal electrodes is made of cobalt and the other one is made of a compound called lanthanum strontium manganese oxide. The organic layer in the new OLED is a polymer known as deuterated-DOO-PPV, which is a semiconductor that emits orange-colored light.Solar solarledlamps are small ones of solar lights.

Energy Matters Offers $1 Drop Solar Deals In Queensland

Queensland households can now defended a solar ability arrangement from Activity Matters from as little as $1 deposit; an accomplishment by the aggregation to advice Queenslanders go solar afore a borderline for the state's solar augment in assessment allurement hits at midnight on Monday.

Once the borderline passes,The consumer market has not been quick to take up bluecrystal1, what was Australia's a lot of acceptable accepted augment in allurement amount will be bargain to a adumbration of its above cocky for households that don't accept their applications submitted in time.

To advice as abounding households as accessible maximise their banking return, Activity Matters is active appropriate solar console arrangement deals until abutting of business Monday, July 9, which can be anchored from as little as $1 deposit.

While how abundant those accepting a solar ability arrangement and appointment an appliance afterwards July 9 will absence out on will alter depending on arrangement admeasurement and location, Activity Matters says the accident in banking allowances could be up to $20,000 over the activity of a system; possibly even more.

After July 9, applicants to the Queensland Solar Bonus Scheme will accept 8c per kilowatt hour for surplus electricity exported to the mains grid, additional a 6 - 8 cent per kilowatt hour electricity banker contribution. This represents up to 68% abridgement of the accepted 44c per kilowatt hour rate. While solar will abide a solid investment post-July 10; the new augment in assessment allurement ante will extend arrangement aftereffect time.Lightology offers over 15000 contemporary indoor and outdoorlight products,

Nokia 808 PureView review: A photographer's perspective

In terms of performance it's not at all bad; from the phone's homescreen a press of the shutter button on the side of the case switches on the camera in approximately 1.5 seconds, and it has a shot-to-shot time of approximately two seconds in 8MP PureShot mode, which is comparable to a good compact. The fact that it actually has a shutter button immediately puts it a couple of rungs further up the quality ladder than most mobile phones.

The contrast detection autofocus system is fast enough in good light, and it has an LED lamp that helps at close range in low light, although at longer ranges it doesn't focus at all well once light gets below late evening levels. It has a tap-to-focus function that is always on, which can be a bit annoying if you don't notice that a careless touch has accidentally moved the focus point to the corner of the frame.Some of the attractions of antiquelamp are the cost savings, the safety and the flexibility.

In fact, the 808's biggest limitation as a camera is the fact that it's in a mobile phone. It's probably quite a nice phone (that's not really my field), but even with a shutter button and a proper Xenon flash, a phone is just not a good shape for a camera. It's awkward to hold it without accidentally touching the screen, which as I mentioned will move the focus point, and despite its relatively compact size it's difficult to shoot one-handed. Even the cheapest budget compact has better handling.

Most compact cameras also have a better list of features. The 808 has no spot metering, no manual white balance setting, no continuous shooting mode, and no delete-all option in playback; the single AF point is too big for accurate focusing, the fact that the flash is right next to the lens makes it prone to red-eye, and the exposure metering is terrible, under- or over-exposing a large percentage of shots. It seems to have only centre-weighted metering, and even minor backlighting such as the sky will cause the foreground to be very under-exposed.

In terms of image quality, it's a mixed bag too. Some people have been raving about it, but to be honest I wasn't all that impressed. One of the main claims is that it's supposedly noise-free, but this is simply not true. Sure, at the 50 ISO minimum sensitivity setting the image quality is undeniably very good, but noise starts to appear even at 100 ISO, and by the 1600 ISO maximum setting it performs no better than any mid-price compact camera.

One area where the sensor does score fairly well is in dynamic range. In the PureView oversampling mode it's certainly above average for both shadow and highlight detail, roughly what I'd expect from a high-end compact. In full resolution mode however the dynamic range is, not surprisingly, extremely poor.

However that's not really the way the camera is intended to be used. It's at its best in the 8-megapixel PureView mode, using the pixel oversampling technology to its best effect. In this mode the colour rendition is very good, with bright vibrant hues in good light, and plenty of fine detail,We have the best brightcrystall2011 for grow project, christmas, rope and strip LEDs. but it's really still not any better than a good 8-10-megapixel compact camera.where you can learn about ledtube as well as buy your bike lights online.

It also suffers from a perennial problem of phone cameras. Because the delicate Zeiss lens is covered with a Gorilla Glass screen to prevent damage, it quickly picks up finger marks and general pocket dirt. Unless you remember to carry a lens cloth with you and clean it before every use you'll frequently find that a slight haze of reflected glare drastically reduces the quality of your pictures. Even with a clean lens, the glass screen is very prone to lens flare in bright sunlight,Police modernlightings play a crucial role in being seen while riding a bicycle, providing safety and security. assuming we ever get any.

Like everything else in the known universe, the 808 can also shoot 1080p video, and it has to be said that the quality isn't bad,LC LED provides eco-friendly energy efficient t5tube. although again it bears the 'for a phone' caveat. It suffers from the usual CMOS sensor "Jello effect" if you pan too quickly, but it has that bright LED light for extra illumination, and the sound quality - mono only of course - is surprisingly good.
