Tips on Buying and Using LED Light Bulbs

Green is good, and right now, energy efficient lighting is all the rage. With the looming phase-out of old-fashioned incandescent light bulbs in many developed countries, people are faced with choosing between a handful energy efficient forms of lighting � compact fluorescents (CFL) and light emitting diodes (LED). This article will help you make good decisions when buying residential LED light bulbs.

CFLs are good for now, but�

You have likely already adopted energy efficient compact fluorescents (CFL) as part of your effort to reduce your carbon footprint. While CFLs are energy efficient, they have drawbacks such as mercury and relatively short lifespan. Also, CFLs are not available in sizes that replace track light bulbs, such as MR16 and GU10. It is unlikely that CFLs will be available in these sizes.

CFLs have made giant inroads over the last couple of years. The low cost and high energy efficiency of CFLs have made them favorites with people replacing incandescent lights. According to the Energy Information Administration, a government agency, 9% of a household�s energy costs are related to lighting. People are genuinely concerned with lowering their energy consumption, and lighting is one of the easiest things a person can improve on. With worldwide support from mass-market retailers, governments, and citizens, energy efficient lighting is seeing a new dawn. While CFLs provide a good combination of efficiency and cost, there is an even better option on the horizon � LED light bulbs.

Introducing the next generation of ultra energy efficient light bulbs � LEDs

LED light bulbs are semiconductors, just like the chips in your computer. These semiconductors emit energy in the form of photons of light. LEDs have come a very long way since they were invented in the 1960s. You have seen LED lamps for decades in the form of indicator lights on electronic products. Now, these LED lamps light bulbs have evolved to the point produce enough light for household and commercial applications. LEDs are extremely energy efficient, and have lifetimes ranging from 50,000 hours to 100,000 hours. LED light bulbs are the perfect complement to your collection energy efficient lighting products.

Tips for Buying LEDs

There are several varieties of residential LED light bulbs on the market. Presently, LEDs best replace track lighting and flood lights, both of which take advantage of the directional nature of LED light. Below are some tips for buying LED light bulbs.

� The Basics

You want to find an LED bulb that produces a healthy amount of light, but at the lowest possible power consumption. A good metric that equalizes your search is �lumens per watt�. To derive this figure, simply divide the bulb�s number of watts into the number of lumens. Right now, a good LED bulb should have at least 40 lumens per watt, but preferably more.

The question is often asked about comparisons between normal light bulbs and LEDs. Here are some examples to guide you:

5-watt, 3 high power CREE LED, MR16 ~ 25-watt MR16 Halogen

5-watt, 3 high power CREE LED, E27 spot ~ 30-watt E27 spot Halogen

6-watt, 165 traditional LEDs, PAR38, ~ 50-watt PAR38 incandescent

� Lifetime of Bulb

Many manufacturers of LED bulbs claim lifetimes of 50,000 hours to 100,000 hours. The lifetime of an LED lamp is generally considered to be the point where the light output has declined to 70% of it�s initial output, measured in lumens. So, a 300 lumen LED bulb with a lifespan of 50,000 hours will have 210 lumens at the end of it�s lifetime. However, the lifetime of a bulb does not mean it is unusable, only that it�s light output has degraded to a certain point. The LED bulb may continue to be useful for several thousand hours past it�s stated lifetime. Unlike old-fashioned light bulbs, it is extremely rare for an LED light to simply burn out. Rather, it will gradually fade over time.

� Color

As a general rule, you should use warmer light indoors, and whiter light outdoors. A color temperature of 2500-4000 Kelvin works great indoors. You should use a bulb with a color temperature of 5000-7000 Kelvin outdoors, as the whiter light allows your eyes to see better at night.

White light in the 5000-7000 Kelvin range is also excellent for display cases, boutiques, artwork, or other settings where you need excellent color rendition.

� Type of LED lamp

LED light bulbs use one or more tiny semiconductor lamps to produce very focused light. Contrast this with normal light bulbs that generate light in all directions. LED lamps are currently available in two forms: traditional LEDs (typically 5mm), which are smaller, and high power LEDs. Light bulbs using traditional LEDs require a large number of LED lamps to produce sufficient light, whereas high power LED bulbs use one or more lamps to generate light.

In general, the more LEDs, the better the light dispersion. Always get LED bulbs with more than one LED. You will find that single LED bulbs produce a very conspicuous outline, similar to a halo. Unless you enjoy halos across your walls, it�s better to buy light bulbs with multiple LEDs.

Here are some common track light and flood light bulb types, and suggestions for the LED arrangements:

For track bulbs such as MR-type and GU-type, try to get bulbs with 3 high power LED lamps (preferably using CREE or Nichia lamps). Avoid buying track bulbs using an array of traditional LED lamps, as these are not as effective as high power lamps.

For flood light bulbs, such as PAR-type, you can find reasonably priced traditional LED arrangements. High-power LED flood lights produce good light, but are also very expensive. In my experience, a PAR bulb using 120 or more traditional LED lamps works just as good, at a fraction of the price.

� Cost and energy savings

LED bulbs have a higher upfront cost, but they pay for themselves several times over their lifetime. Because LEDs have lower power consumption and a very long lifetime, they are very energy efficient. Let�s take an example of a $45, 5-watt, 50,000 hour MR16 LED bulb. Let�s assume a constant electricity cost of $0.10 per kilowatt hour, and a 0.61 electrical grid CO2 output factor. Compared with a similar $8, 25-watt halogen MR16 bulb, the LED will save $255 and reduce carbon emissions by 1,345 pounds. Not bad for a light bulb.

As energy costs continue to rise, the cost savings and carbon reduction from using LEDs will become far more pronounced.

Buyer beware � LEDs cannot replace general illumination bulbs (yet)

Right now, there are plenty of options for LED light bulbs. And that�s a bit of a problem. Several sellers of LED bulbs claim their bulbs are powerful enough to replace general illumination bulbs such as incandescent and CFL. This is simply untrue. Many of these �replacement� bulbs cost nearly $100 and use over 10 watts of power. You are much better off using a $3.00, 10-watt CFL for now. However, keep an eye out for LED general illumination bulbs over the next few years, as they will become very competitive with normal light bulbs.

Start today with LEDs

As LED technology rapidly advances, you will see them replace all other forms of light bulbs, including CFLs. If you have track lights or flood lights, you can begin incorporating LED light bulbs right away. Remember, now is the time to take steps to save energy and money. Your wallet and the planet will both thank you.

Ceiling Light for Beauty and Function

Ceiling light is the most common and fundamental type of lighting for homes and businesses as it's the main source of ambient light - the main illumination for a room. Adequate ambient light is essential for indoor living and working so it has to be high quality. Fortunately, you have a wide choice as ceiling lights take many forms such as fluorescent strips, chandeliers, recessed and non-recessed down lights, pendant lights and track lights. Here's your guide to getting this vital form of illumination right to create that desirable blend of beauty and function.

When most of us enter our homes and offices, the first thing we do is to switch on the ceiling light. The ambient light it produces plays the same role as natural light in providing overall illumination to a space. At one time, you were pretty much limited to a standard shaded bulb or fluorescent strip. These are still common, but nowadays you can also find a whole range of ceiling lights offering the ultimate in style and functionality.

Popular nowadays are down lights. These are mounted in the ceiling and can be used in all the rooms in a home. Downlights produce a soft, even illumination which creates a relaxing atmosphere in any room. You can get them with many different types of fixtures. Recessed down lights are very sleek and stylish. You can get bezels in a range of shapes and the lights are typically finished in white or brushed chrome for a clean, modern look.

Down lights fitted with a gimble make excellent accent lights to highlight special objects or areas in a room. The rotatable design allows you to focus the beam on the desired object such as painting or porcelain item.

When it comes to bulbs you have many choices including compact fluorescent lamps (CFL) or halogen. CFLs are most suited to areas such as kitchens and dining rooms or external use where the lights need to be on for extended periods.

Halogen ceiling lights are very popular nowadays owing to their combination of energy efficiency and stylishness. These were originally designed for use as accent lighting; they're now popular as task lights for illuminating cooking spaces in kitchens for example.

The most celebrated types of ceiling lights are chandeliers which date back to medieval times and grace some of the world's most glorious buildings. Their enduring popularity is due to the shimmering blaze of luminescence they produce. Often, they're bought for their decorative value as much as their illumination. The good thing is, you don't have to live in a palace to grace your home with a chandelier; you can find affordable items to fit any room, whether coloured or crystal, in antique gold or polished brass.

Other popular options are pendant lights. These hang down from the ceiling and are perfect as task lights above a kitchen work space or a dining table, for example.

So, how to choose the most suitable ceiling lights?

In your home, each room will have different demands. Every room requires ambient lighting and your living room demands the kind of gentle relaxing light that downlights provide along with strategically placed task lighting, in the form of track lighting or pendant. You kitchen needs effective task lighting for cooking and your bedroom needs soft lighting that down lights provide to create the bedtime mood.

For commercial lights, it depends on the kind of business you're in. If you have an office that uses a lot of computers such as a graphic design company, you'll need to keep your main ambient lighting low to avoid screen glare and use accent lighting to fill in.

For an up market restaurant, chandeliers add that touch of glamour that really sets off a room. If you're the owner of a high end boutique, you'll want to maximize the use of accent lighting to bring out the best in your merchandise. You could set up track lights to shine a spotlight on key areas, and you'll probably want to experiment with coloured bulbs.

You have a vast choice when it comes to ceiling light. The best way to get ideas is to visit an online lighting wholesaler and browse the offerings of domestic and commercial lights. You can choose the best lighting for your particular needs and buy chandelier or track lights as you need. After ordering online, your goods will be delivered in a few days.

Lights For The Dream Home

One of the best ways to transform your home is through the judicious use of lighting. For effective illumination doesn't just light your home, it also confers safety, comfort, style and even a sense of drama to all your rooms. But that's only if you do things right. Here's your guide to lights for the dream home.

The key to getting the illumination right in your home is first to understand and then artfully apply the main types of lighting you have at your disposal. Essentially you have three main types - ambient, task and accent - and each one has its own uses and applications.

Ambient lighting comprises the main lights that give overall illumination to a place. All spaces need this light as it works as natural light to make it possible to function in an area. The main source is ceiling lights that provide direct ambient light covering the whole room. Another type is indirect ambient lighting which shines upwards and produces a more diffuse illumination. Or you could decide to combine both.

Task lighting is a specialised form of light used to illuminate spaces where activities are carried out. In the home, reading and cooking are the most common activities. Examples are the use of special reading lamps, and pendant lights that hang down from the ceiling in the kitchen to provide the illumination you need to function effectively.

Accent lighting, the third main type, works to highlight special objects and areas. These can include paintings, porcelain pieces, flower arrangements and tapestries, for example. Ceiling mounted spotlights and track lighting are popular here, along with floor lamps which direct their beams upwards. Another popular application is cabinet lights that work to accentuate objects on a shelf such as vases and ceramic pieces. Task lighting can also balance ambient lighting by bringing light to shaded corners.

Now that we're familiar with the various types of lighting, it's time to consider the types of fixtures available. Lighting fixtures are the structures that hold and provide power to the bulbs. They vary as to the types of light you wish to install, the effects they produce and also how they themselves look. For example, recessed lights are extremely sleek and stylish in appearance, while chandeliers offer a timeless elegance to any setting. Meanwhile, track lights are an extremely flexible solution to your accent lighting needs. These are long tracks that can hold as many spotlights as you wish (space allowing).

Once you've installed your lighting, you can tweak the settings until you're completely satisfied. Track lights can be adapted to take pendant lights, for example. Plus, you can try various bulbs to see the result. Different bulbs create differing warmth, clarity and brightness, each of which can make a tremendous difference to the atmosphere of your rooms. You can also experiment with shades until you get the desired effect. Other tools at your disposal include dimmers which allow you to set the lighting to your chosen level.

The type of bulb is important for both the quality of the light and the atmosphere it creates. Incandescent bulbs produce a warm yellow light and are best for spaces such as the living room; fluorescent lights give a bright white light that's effective but can be harsh. It's best for use in rooms like the kitchen where work has to be done.

Now that you know the mechanics of lights, you should determine the following three matters about each room - what tasks will be carried out there, what mood or atmosphere do you want to create, and what type of illumination will provide a comfortable environment. This will guide you to getting the right lights for each room and thus transforming your home. A great way to get inspiration is to browse the web sites of lighting wholesalers and see the range of products you have to choose from.

One exciting thing to remember is that the world of illumination is a constant state of development. You can now get modern lights that offer great versatility. An example is the dual purpose light that comprises one lamp shining upwards to the ceiling to create ambient light with a standard lamp that creates task lighting for reading. These types of lights offer great flexibility and allow you to illuminate your home with ease and convenience.

You can find the best in modern and traditional illumination by visiting the web sites of online lighting wholesalers. By buying your chandeliers online, along with all your other needs, you can get the widest range of products at the best prices.
