CFLs Vs. LEDs Consumer Guide

A proper lighting in your home can make an enormous difference in your home’s ambiance and overall comfort of your home.

LEDs which have been used for decades in many opto-electronic components, are now making a strong move into household light bulb market. Can these more expensive, energy efficient, greener and longer lasting light bulbs replace the current King – CFLs in the near future as a lighting bulb product of choice for the environmentally conscious consumers?

Proponents of LED light bulbs claim that LEDs are not only energy efficient and environmentally friendly, but can also last 10 times longer than CFLs. One fact that is not often mentioned though, is that similarly to the early CFLs, modern (early) household LEDs provide only a limited amount of brightness that usually does not exceed the level provided by a 35-watt incandescent light bulb. This is considered to0 little for focused tasks like reading and writing for most people.

The higher price of LEDs and limited brightness is what makes choosing between CFLs vs. LEDs rather difficult. At any rate, it helps to know what each of these “green lighting alternatives” to incandescent light bulbs has to offer.

In a nutshell

You have surely seen many CFLs, or Compact Fluorescent Lamps. They have spiral shapes and are primarily used in homes as an affordable and greener (more energy efficient) alternative to incandescent light bulbs. Unlike their predecessor, incandescent light bulbs, CFLs do not contain any filament that produces a lot of heat and some light when the electricity passes through it. Only a small proportion of electricity goes towards light generation in incandescent light bulbs, while a great amount of electricity is wasted as heat. This renders incandescent light bulbs energy inefficient and is the reason why CFLs became a popular replacement option.

Further, frequent Ons and Offs can dramatically reduce a lifespan of incandescent light bulbs because of rapid expansion and contraction of the filament, which leads to a premature failure of incandescent light bulbs.

LEDs or light emitting diodes, produce light whenever an electric current passes through them. LED light bulbs are far more energy efficient and longer lasting than CFLs, but they also cost more, and have a rather limited brightness and narrowly focused light distribution range.

LEDs are illuminated by the movement of electrons in a semiconductor material, there is no filament to burn out. Thus LEDs can last as long as a standard transistor, in theory. In practice, LEDs generate some amount of heat, and frequent Ons and Offs can lead to cracking of the epoxy and the circuit board, which can lead to a shorter lifespan than 50,000 hours (10 years) claimed by many.


Viable – Brighter LED Light Bulbs Alternatives

EvoLux LED Light Bulb

13 Watt EvoLux LED Light Bulb – 100 Watt Incandescent Replacement

EvoLux S 13 Watt LED Medium Base Light Bulb producing Warm White Light equivalent to a 100-watt incandescent light bulb (According to Manufacturer). It uses use multiple LEDs in a single casing to generate light. This bulb can be purchased for about $60 per bulb as of the date of this post May 1st, 2011. The price tag may still be too high for many homeowners to swallow.

Further, many people who have purchased LEDs for their home, report that the amount of light produced by EvoLux LED light bulb is no where near to what the manufacturer claims, and is roughly equivalent to the amount of light produced by the 60-75 watt incandescent light bulb. The narrow focus of the bulb is also a concern for many homeowners.

Concerns about Chemicals in CFLs

LED light bulbs do not have any significant chemical content, while CFLs contain mercury and thus require a proper recycling. Recycling of old CFLs does not have to be difficult, though. You can simply return them to the hardware store where you originally bought them for a proper recycling. If the CFL light bulb breakage occurs, you and your family can be exposed to to the risks posed by the small amount of mercury it contains. Be sure to open the windows and properly clean and ventilate the space where the breakage occurred.

Heat Production is Minimal in LEDs

LED light bulbs generate a very small amount of heat compared to CFLs and incandescent light bulbs. Naturally, the risk of fire hazards is reduced. In fact, you can even touch the lamp itself without getting hurt. Most electricity goes directly towards producing the light in LEDs.

More savings for everyone

There is no denying that nowadays many people are making extra efforts to make ends meet. Thus, every opportunity wherein you will be able to earn bigger energy savings will come as a welcome thought especially to people who are environmentally conscious and green oriented, right? With LEDs many people can recoup the higher initial cost of LEDs in a few years. Thus LEDs, can actually be a cost effective alternative to CFLs event today!.


Benefits of LED Light Bulbs Vs. CFLs

LEDs get bright as soon as they are turned on. CFLs do not work that way. Instead, they need to be warmed up for about a minute in order to achieve their brightest.

CFLs are made of materials that break easily such as its glass tubing that is extremely thin. Thus, once dropped, they break into pieces making it useless. LED lamps are more durable because of their solid materials that are far less susceptible to breakage caused by the impacts like accidentally dropping the bulb.

Advantages of CFLs

Looking at the other side of the fence, CFLs also have their own share of benefits and advantages. Apart from its cost, CFLs can provide brighter lightning than LEDs. For those who prefer dimmer shades, newly released CFLs have available dim lights already. On top of it, LED technology is still new and therefore expensive and not yet fully developed.


Conclusion and Forecast

While immediate energy-cost savings from using LEDs are dubious at this point it time, the green benefits of using LEDs are quite clear. Cost-wise, LEDs will become more affordable and are likely to replace CFLs altogether at some point in the near future.

HQ LED Light Bulbs for Your Home

LEDs or Light Emitting Diodes can be an excellent choice for lighting your home, but there are a wide range of different LED light bulbs to choose from, so it is important to consider your choices carefully before you make your purchase.

LED Light Bulbs

LED light bulbs are a type of semiconductor. As electricity passes through them, they produce light energy. The chemicals which the LEDs and the surrounding bulbs contain will determine the color of the light that is emitted. The energy efficiency of LED light bulbs stems from the fact that they convert most of the energy that they use into light. With incandescent light bulbs, a lot of the energy is lost in the form of heat. This makes incandescent light bulbs far less energy efficient. The difference between the energy efficiency of incandescent and LED light bulbs can be huge. An LED light bulb can be as much as 90 percent more energy efficient than an incandescent bulb.

HQ LED Light Bulbs

HQ LED light bulbs are modern and compact lights that offer excellent energy efficiency. HQ aims to produce brighter, more energy efficient LED bulbs for everyday use in the home. HQ LED light bulbs are carefully tested to ensure they will offer good value for money and keep working as long as possible.

HQ LED bulbs come in a range of different sizes, shapes, colors and styles, so you can find the right type of LED light bulb to light your home. You may be looking for light tubes, globe shaped bulbs, ceiling lights, spotlights or light strips, to create different types of lighting effects.

Advantages of LED Light Bulbs

LEDs can be more environmentally friendly than either traditional incandescent light bulbs or the newer energy saving light bulbs, which are usually Compact Fluorescent light bulbs (or CFLs). A CFL bulb is more energy efficient than an incandescent light bulb, but it is still only about half as efficient as an LED light bulb. A 10 Watt LED light bulb can provide the same amount of light as a 20 Watt CFL bulb. An LED light bulb will usually save you about 80 percent of the energy that you would use with an incandescent light bulb.

Although CFL bulbs do offer some important advantages over incandescent light bulbs in terms of energy efficiency, which can help to reduce your energy bills and which can also offer some important environmental benefits, LED light bulbs can provide greater energy efficiency in combination with some other important advantages. LED light bulbs will reach full brightness immediately and they can be turned on and off frequently without experiencing any damage. They can also be a lot more attractive than CFL bulbs and they can be used in lights that use a dimming feature, unlike CFL bulbs.

LED light bulbs also do not contain the same toxic chemicals as CFL bulbs. This means that they are a much more environmentally friendly option when it comes to disposal. CFL bulbs contain mercury, which can be very harmful for the environment, so they can result in serious pollution problems during disposal.

LED light bulbs can last a lot longer than either incandescent light bulbs or CFL bulbs. You will enjoy the convenience of not having to replace your light bulbs as often, as well as the financial savings on the cost of buying new light bulbs. LED light bulbs are usually designed to last for 50,000 hours of use. A single LED light bulb can last as long as 25 conventional incandescent bulbs.

LED light bulbs do not usually experience a sudden failure, which can happen with other types of light bulbs. This can make an LED light much safer since it is very unlikely to fail suddenly when you need it most, for example when you are about to go down the stairs. When LED lights fail, it is usually through a gradual dimming, so that eventually they will lose enough of their brightness that they will need to be replaced. Typically, it can take between 35,000 and 50,000 hours of use for an LED light bulb to lose half of its original brightness.

The main disadvantage of choosing an LED light bulb rather than an incandescent or CFL bulb is that the initial cost of buying the bulbs tends to be higher. However, these higher costs are offset by the longer lifetimes of the bulbs, which means that they need to be replaced less often, and by the superior energy efficiency. Since they need to be replaced less often and because they can reduce your energy bills, an LED light bulb can end up being cheaper than the alternatives in the long-term.

Choosing the Right HQ LED Light Bulb

If you want to use HQ LED light bulbs in your home, you will need to make sure that you have the right type of light fittings for these bulbs. It is possible to use LED light bulbs in many different ways, including as lighting strips, as the main ceiling lights in your room or in lamps. You can either install LED light fittings or use an adapter to convert an existing light fitting or lamp into an LED light.

HQ LED light bulbs come in a range of different shapes. Light bars and strips are ideal for creating atmospheric lighting. Spotlights are a good choice if you want the light to be focused in a particular direction. They are ideal for table lamps, tracked lighting and recessed lighting. Globe LED bulbs are the best choice if you want to light an entire room since they spread the light out over a wide angle. However, you should remember that if the light is being dispersed in this way, it will seem less bright, so you need to buy a more powerful bulb if you want to achieve the same brightness with a globe bulb as with a spotlight.

As well as choosing the right shape bulb, you will need to consider the color. In terms of color, you will probably be looking for a white bulb, although it is possible to find colored LED bulbs that produce lights of all possible colors. However, even if you are choosing a white LED bulb, you will find that there are a range of different options. These are usually referred to in terms of color temperature. Warmer lights produce a softer, yellower light rather like the sunlight at dawn or dusk. Colder lights produce a whiter or bluer light rather like moonlight. Cooler color temperatures of 5000 to 7000 Kelvin are suitable for outdoor use, while color temperatures of 2500 to 4000 Kelvin are better indoors. Cooler white lights will be brighter than warm white lights, even if they use LED bulbs of the same power. This is because the color temperature of the warm white light is created by a coating of phosphor on the bulb. This dims the light at the same time as changing the color.

As a bare minimum, you should ensure that you choose an LED light bulb that produces 50 lumens per watt. However, you will be able to enjoy a brighter light if you choose an HQ bulb that produces 75 or 100 lumens per watt. Using lumens rather than watts gives a better idea of the brightness of an LED light, which works very differently to the incandescent light bulbs that are measured using watts. Lumens are a measurement of the amount of light that is being emitted, while watts are a measurement of the amount of power being used by the light. A 100 watt incandescent light bulb typically produces about 1500 lumen of light.

A 3 watt high power LED bulb is comparable to an incandescent light bulb of 25 watts. A 9 watt high power LED bulb will be comparable to a 50 watt incandescent light bulb. An 18 watt high power LED bulb is comparable to a 100 watt incandescent bulb.

It is also important to consider the angle over which the light will be spread. Light bulbs with wider angles will be less focused, but the light that they produce will be dimmed as it will be more dispersed. You will therefore need to choose a brighter or more powerful bulb if you are choosing a wide angle bulb.

Most LEDs have beam angles of between 30 and 70 degrees. The smaller the angle, the more focused the light will be. However, you can also find bulbs with wider beam angles, which will spread the light over a larger area, producing an effect that is more similar to a traditional light bulb. If you are looking for a more dispersed light rather than a spotlight, you should look for an HQ LED bulb with a beam angle of at least 120 degrees.
