Energy adviser: LED lighting not yet practical for many uses

26 Mar

With a countdown under way to eliminate incandescent light bulbs from store shelves by Jan. 1, what should consumers know about LED lighting as an alternative in the home?

The Energy Independence and Security Act of 2007 set in motion a transition mandating that all light bulbs use 30 percent less energy than current incandescent bulbs by 2014.

As part of the change — between Jan. 1, 2012, and Jan. 1, 2014 — all conventional incandescent light bulbs with ratings between 40 watts and 100 watts will be gone from the U.S. market. The change does not mean that consumers can’t use incandescent bulbs, just that retailers can’t sell them.

Replacement options from manufacturers come in the form of compact florescent lamps, called CFLs, and light-emitting diodes, called LEDs. This column focuses on LED technology.

An LED is a semiconductor light source that releases energy in the form of photons across a luminescent spectrum. According to industry experts, LEDs offer advantages over incandescent light sources because of their lower energy consumption, longer lifetime, improved robustness, smaller size, faster switching, and greater durability and reliability. However, LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamp sources of comparable output.

The advantages of LED lights are that, in addition to their higher energy efficiency, they have a longer life, are rugged and do not contain mercury.

Their disadvantages? More expensive than incandescent bulbs or CFLs and their light output is limited to lower-light-level applications.

According to a report by Portland General Electric, “Because LEDs cast light in one direction at a narrow angle, they are not yet practical or cost effective for general illumination.” In addition, their heat sensitivity can hurt performance and longevity.
Consumers must be informed

Bob West, an energy adviser with Clark Public Utilities in Vancouver, acknowledges that there are still industry “issues” with LED products. Consumers must study up on what LED products are worth the investment and where they best should be used.

To assist consumers, as well as manufacturers and retailers, the U.S. Department of Energy has established a website at The DOE also has developed a new Lighting Facts label for LED lighting.

Why? “The rapid growth of LEDs has resulted in an increasing number of new products on the market,” according to the DOE. “While many of these products showcase the energy-saving potential and performance attributes of LED lighting, under-performing products are also appearing in the market. Since bad news travels fast, such products could discourage consumers from accepting this new technology.”

When CFLs came to the market a few years ago, the same product challenges and slow market acceptance occurred, the DOE said.

To help consumers sort through the information, new Lighting Facts labeling has been introduced to help “evaluate product performance against manufacturer claims.”

Lighting Facts labeling should not be confused with Energy Star ratings. While Energy Star differentiates products that are above the minimum standards, the Lighting Facts label is an industry tool to help retailers and other buyers better select and understand the products they are selling, DOE’s website said.

“Armed with this information, retailers and other industry stakeholders can keep poorly performing products from reaching their shelves,” the agency said. The good news is that the technology is improving rapidly. New energy-efficient consumer LED lamps have been announced from three of the lighting industry’s largest producers, Osram Sylvania, Philips, and General Electric. As with many new technologies, mass production will mean lower costs and improved performance of LEDs over the next several years.
Certain uses make sense

Clark Public Utilities’ West said that in certain lighting applications in the home LEDs make sense, such as in-can lights at the top of a vaulted ceiling. But because of their higher cost, LEDs are really no more economical than a fluorescent in most applications. To see that you are getting the most for your money, make sure the LED products you buy have been registered and approved to use the Lighting Facts label. This labeling becomes effective on July 1.

Introduction of Brighten your home with LED lights

09 Mar

People cannot decorate their home or any other venue without proper lighting. Lighting is very important for each and every occasion. Different types of LED lights are available in the market at reasonable rate. LED lights are available in various designs for specific purposes, such as flood lights, spot lights, down lights, etc. One of the popular forms of outdoor lighting is LED landscape lighting. LED lights come with AC-DC power supplies for electrical savings. Before sometimes, incandescent, fluorescent or halogen bulbs have been used as the conventional sources of lighting. After some period of time, LED or light emitting diode is introduced that refers to a semiconductor device, which is used for exchange of electricity to light.

At the time of introduction of LED lights, it produces low intensity red light, but now, many different advanced versions of LED lights is produced. Many people prefer LED lighting as standard in homes and business everywhere. LED lighting and light emitting diodes becomes the first choice of the people because it is more efficient way to illuminate a room. The movement of electrons is utilized by LED lighting for power and light. The LED lights are manufactured in such a way that a huge amount of photons are released outward and the light from a diode is centered via the end of a plastic bulb that makes a bright glow.

About a third of the electricity is used by LED lighting and offering approximately 60,000 hours of light. With the help of LED lighting, one can create the atmosphere of natural light in the winter months that is essential for the person who is suffering from SAD. LED lighting has a tendency to mimic natural, outdoor light. LED lighting cuts down on energy demands significantly since the electricity that is used in it is being directly used for light.

Recessed LED Lights Save Energy and Look Great at the Same Time

19 Feb

In addition to their energy effectiveness, a single on the greatest factors about LED lights is their versatility. You can do as a lot with vitality saving LED lights as you are able to with incandescent or compact fluorescent. Recessed LED lights, one example is, seem fantastic in equally modern-day and common homes.

LED, which stands for light-emitting diode, is really a semiconductor light supply that delivers just one wavelength of light when it is electrically charged. A single matter individuals could possibly must think about when you are looking for your proper LED lights for their homes is CRI or shade rendering index. As explained by EERE. Energy.Gov, colour rendering index is a “measure of how very well light sources render the coloration of objects, materials and skin tones.” The a lot more genuine they want things to appear, the a lot more thorough they will have to be with regards to the kind of LED lights they invest in. Cool white LED lights, as an example, have a bluish glow, so anything they illuminated would glimpse blue. Warm white LED lights possess a yellowish tint, similar to incandescent lights, and organic white is far more like daylight.

Recessed lights isn’t only acceptable in ceilings. It may possibly be used in floors, also. The ground application is, generally, noticed in trend displays or other industrial utilizes, but you could have recessed lights inside floor of your bathroom or patio. To more add to their vitality effectiveness, it is possible to use solar LED lights outdoors as part of the recessed lighting in your deck or patio.

You will get them in bright white, warm white, cool white or within a number of other colors. Photo voltaic LED lights which are utilised outdoors as recessed walkway lights come in square panels, also. The square panels get the job done mainly perfectly when utilised to light the edge of a swimming pool. As with most other varieties of LED lights, recessed LED lights and outdoor solar LED lights can be found in dimmable styles.

LED lights for houses makes sense, primarily, due to the dollars you can conserve. You may need to shell out a lot for LED lights at first, but because they very last for countless hours and eat such a smaller amount of energy, you end up conserving funds around time. For the reason that incandescent lights will quickly develop into obsolete, it is essential for people today to get used on the plan of employing LED lights to replace the incandescent lights in their houses. Compact fluorescent lights are nonetheless an alternative, however they incorporate poisonous mercury.

How LED Lights Can Shrink Electric Bills

05 Nov

LED lights have been considered a luxury within lighting technology, but it has proven and practical uses that could save any household plenty of money. With improved technology, LEDs are now capable of lighting a house by replacing some standard bulbs, and in the form of specially crafted LED lamps. Read on to discover just a few reasons why this technology is so good at saving users time and money.

Light emitting diodes, as the letters in LED stand for, are a very clean source of energy. By firing electrons, the smallest atomic particles, instead of filaments, these lights are much brighter within a smaller glass area than most incandescent bulbs three or more times their size. The concentrated power within a diode gives it not only a brighter appearance, but a better way to make more light out of less energy.

It is known that incandescent bulbs are only capable of using around twenty percent of the power fed into them to make light, with the other eighty converted straight into heat. LEDs on the other hand offer the exact opposite case, with eighty percent put toward light, and only twenty wasted on heat. Although no light created so far is a perfect converter, diode technology has started to come close.

Another way which these little lights save their owners money is through their increasingly impressive longevity. An individual light has proved in studies to last over a decade of constant use, and two decades of occasional use. Since users do not have to replace these lights on a yearly basis, their single investment into a bulb pays for itself quickly, and begins saving energy for many years to come.

Governments and commercial businesses have also taken notices of LED benefits, made apparent by their use in both stoplights and high-definition televisions. Due to their incredible longevity, they are able to save local governments the same costs as home owners on electricity, time, and maintenance. Because LEDs come in such a variety of colors, they can be very useful for creative designers, toys, and tools that call for the use of a small, bright light.

Although lights are necessary to see the world, they are also credited with the gradual loss of eyesight. Doctors have found that certain high-frequency light waves are much more detrimental to vision sensors than simpler, low-frequency lights. In comparison to the sun and certain other lighting fixtures, LED lamps have shown significantly less effect on eye strain.

With regular updates in the world of LED technology, people are able to bring this new form of light into their home for many kinds of uses. Bulbs are made with clusters of individual diodes when a fixture calls for size, such as a candelabra or wall sconce. Their reliability also makes them a wise choice for use in any kind of emergency lighting device, like a flashlight, for those times when the electricity fails.

LED lights can contribute a simple way for any home to save electricity and utility expenses. Their technology is an expanding field, making their use more practical on a residential level each year. Good for the environment, eyesight, and the bank account, they are definitely worth further research from interested individuals.

LED Light Boxes, Light Up Your Marketing

12 Jul

LED lights can last for up to 30 years and use much less power than conventional bulbs, so they are ideal for light boxes. The strong yet pleasant light emitted by LEDs can be used to create decorative light boxes for displaying any photo, graphic, poster or document you want to draw attention to, especially in permanent displays.

Although LED boxes cost more, the initial expenses are quickly regained in both replacement costs of bulbs and energy saved. Compare the lifetime of a florescent bulb — 15,000 hours maximum — to the 100,000 hours of use an LED bulb produces and it is easy to see how just eliminating the chore of replacing bulbs can be a distinct advantage. LED bulbs also come in a range of colors that can be installed to complement your graphics. Commercial businesses are finding LED light boxes to be a perfect way to advertise both outside to attract customers and inside to promote in-store sales and special offers. The shadow-free illumination provided by professionally designed LED light boxes includes technologies that transfer the bright light from the edge of the box to the center. They are also much lighter and thinner than florescent or conventional light boxes so they are easier to install and relocate as needed.

LED light boxes are perfect for companies who have booths at conventions and trade shows. Freestanding displays made with LED light boxes can attract attention and generate interest in your product or service. You can change the graphics as often as you like for different events and promotions. You can even use these lightweight attractive light boxes in the lobby of your business when they are not on the road to give your entrance a professional appeal.
LED light box pedestals are also very useful for businesses who need to display directories or provide convenient maps for their visitors. The steady, even transmission of the LED light in a pedestal box makes all points visible in the display so even the fine details are easy to read. When you attach it to a permanent sturdy frame, you can place it in high-traffic areas since it is durable and requires little to no maintenance. LED Boxes can also be designed to include audio loops for informative messages and directions. Some LED light boxes have been adapted to react to musical beats, pulsing on an off in synchronization with the music. These create an excellent ambiance for entertainment venues and restaurants and also can liven up convention displays.

Because they use so little power and are so thin and light weight, LED boxes are an excellent choice for advertising at mobile venues and can be put to good use on DJ stages, as menus for food service trailers or a merchandise list for mobile retail merchants. LED light boxes can be run on rechargeable batteries if needed, or plugged directly into the car battery with cigarette lighter adaptors.
