FLIPPING THE SWITCH ON LED BULBS
The bulb is an LED (light-emitting diode), not just a highly evolved version of the incandescent light, but a new class of appliance entirely. It's a device with a low running cost, and after years languishing on shelves, it's finally a cheap, good.
There are many reasons to choose LED lighting over traditional, bulbs halogen and fluorescent bulbs and these are just some of them...
Why Choose Modern LED Lighting?
It's all well and good to offer such a wide and varied selection of LED related goods, but unless you are already aware of the potential benefits of LED bulbs over regular, traditional forms of lighting, you might be a little reluctant to give this concept further thought. So, in order to clear up any potential queries you may have with regard to LED lighting and related products, here are five rather impressive reasons to check out this format in a little more detail and, as a result, reap the benefits.
Whilst this might not be something you have considered in too great a detail, LED lighting is actually far safer than other, more traditional forms of lighting and the related bulbs. LED bulbs manage to provide you with a long lasting and impressive level of lighting whilst also maintaining the unique stance of being able to completely avoid harmful chemicals such as Mercury. Traditionally speaking, many bulbs contained a range of less than wonderful chemicals but with an LED bulb, such issues are avoided.
Now, this is something which will no doubt be on everybody's mind where lighting needs are concerned as, put simply, nobody wants to have to be constantly replacing faulty bulbs or stocking up for exactly this kind of eventuality. Thankfully, an LED bulb is the kind of item which has been proven to possess a much, much greater life span than other types of bulb and the levels of efficiency are certainly worth shouting about. LED bulbs are also efficient in another way. Those traditional, incandescent light bulbs which we all remember have a tendency to utilise just 20% of the electric current it uses for production of light. This means that a very sizeable 80% of the energy is wasted as heat. LED bulbs on the other hand do not have this problem, which leads us on to point three.
It is perhaps something which you are sick of hearing about, but reducing the amount of energy you use can of course have some rather beneficial repercussions, environmentally speaking. LED bulbs use much less energy than traditional bulbs and as such, by making use of such a concept, you can reduce your carbon footprint and make savings at the same time.
Pretty self explanatory this one; reduced energy consumption doesn't just benefit mother nature, it can also impress your bank manager to boot as long term savings are guaranteed.
This might not be something which you have thought about too frequently, but what if you suddenly decide that a room or space of yours needs a brand new edge? Is it really that easy to get hold of different coloured bulbs? Well, in terms of LEDs, it couldn't be easier as there really is magnificent scope out there in terms of colour and style.
LED Lighting means the light source of the lamp is LEDs, LEDs have many types: Miniature LEDs, Five- and twelve-volt LEDs, Flashing LEDs, High power LEDs, Multi-color LEDs, Alphanumeric LEDs and so on. And LED Lighting can be in many fields:

What does LED stand for? - A Light Emitting Diodes.
What’s so great about LEDs? LEDs can be used to build energy-efficient lighting products that save energy, help protect the environment, reduce maintenance costs and make people and things look much more attractive than traditional lighting. And they can last much longer than traditional lighting. A Light Emitting Diode (LED) is a semiconductor device which converts electricity into light. LED lighting has been around since the 1960s, but is just now beginning to appear in the residential market for space lighting. At first white LEDs were only possible by "rainbow" groups of three LEDs -- red, green, and blue -- by controlling the current to each to yield an overall white light. A blue indium gallium chip with a phosphor coating that is used to create the wave shift necessary to emit white light from a single diode. This process is much less expensive for the amount of light generated.
Just how energy-efficient are LED lights?
LED lighting can save up to 85 percent of the electricity used by incandescent bulbs and up to 50 percent of electricity used by fluorescents. When comparing LED lighting to fluorescent lights, energy savings depend on the type of fluorescent light. For example, LED lighting can save up to 50 percent of the energy used by CFLs and between 20 to 30 percent of the energy used by fluorescent tube lighting
LEDs, or light emitting diodes, are extremely energy efficient and extremely long-lasting light bulbs. LEDs are just starting to hit the consumer market in a big (affordable) way. In most locations, they still cost quite a bit more than even CFLs, but use even less energy and last even longer. An LED light bulb can reduce energy consumption by 80-90% and last up to 50,000 to 100,000 hours. Christmas lights using LEDs have come down in price, but make sure you like the set you buy, as they may last you your lifetime given the few hours per year that they are turned on.
Listed below are a few benefits of Solid State Lighting: LEDs
Unparalleled maintenance savings - This is where LED lighting makes most sense, especially for homes, municipalities, large facilities, building owners, that incur large costs relative to their lighting systems. Let’s look at some factors that affect your maintenance costs.
Long life- How often do you change your lamps? White LEDs currently have a usable life of 30-75,000 hours and growing. Usable life of solid state lighting is the amount of time passed before a reduction of lumen output is 30% less than initial output. How long is 50,000 hours? Or how about 100,000 hours.
50,000 hours? Depending on bulb life.
- 50,000 hrs running 24/7 365 days a year = 5.7 years.
- 50,000 hrs running 12 hrs a day 365 days a year = 11.4 years
- 50,000 hrs running 08 hrs a day 365 days a year = 17.12 years
Can LED lighting really save energy and money?
Take a look at the statistics. The U.S. Department of Energy estimates that widespread adoption of LED lighting by 2025 will:
- Reduce electricity demands from lighting by 62 percent.
- Eliminate 258 million metric tons of carbon emissions.
- Reduce the amount of materials being put into landfills.
- Avoid the building of 133 new power plants.
- Save the US over $280 billion
Why is LED lighting better than incandescent bulbs?
Most of the energy emitted from incandescent bulbs is converted to heat instead of light. That’s why you’ll burn yourself if you try to touch an incandescent bulb once it’s turned on.
LED lighting is about 85 percent more efficient than incandescent bulbs. Since LEDs consume significant less energy, they don’t emit as much heat. That’s why you typically won’t burn yourself if you try to touch an LED light once it’s turned on.
LED lights are also designed to last about 50 times longer, which means less maintenance and less waste.
Why is LED lighting better than fluorescent lighting and CFLs? LEDs don’t contain hazardous materials, such as mercury. Since fluorescent tubes and CFLs contain mercury, they must be properly disposed of in order to prevent mercury from poisoning landfills. Here are some tips from the U.S. Environmental Protection Agency on how to dispose of fluorescent lights.

The small size of LED lights encourages a variety of design options. White LED lamps are available with Edison (screw-in type) bases to retrofit existing fixtures. There are LED strips that can be used under cabinets. In addition, outdoor landscaping fixtures are available.
LEDs emit more light per watt than incandescent light bulbs. Their efficiency is not affected by shape and size, unlike fluorescent light bulbs or tubes. LED light sources consume more than two thirds less electricity than conventional lighting. The efficacy of a typical residential application LED is approximately 20 lumens per watt (LPW), though efficacies of up to 100 LPW have been created in laboratory settings. Incandescent bulbs have an efficacy of about 15 LPW and ENERGY STAR® qualified compact fluorescents are about 60 LPW, depending on the wattage and lamp type. Some manufacturers claim efficacies much higher than 20 LPW.
LEDs can emit light of an intended color without using any color filters as traditional lighting methods need. This is more efficient and can lower initial costs.
LEDs can be very small (smaller than 2 mm2) and are easily populated onto printed circuit boards.
LEDs light up very quickly. A typical red indicator LED will achieve full brightness in under a microsecond. LEDs used in communications devices can have even faster response times.
LEDs are ideal for uses subject to frequent on-off cycling, unlike fluorescent lamps that fail faster when cycled often, or HID lamps that require a long time before restarting.
LEDs can very easily be dimmed either by pulse-width modulation or lowering the forward current. LEDs do not change their color tint when dimmed unlike incandescent lamps that turn yellow.
In contrast to most light sources, LEDs radiate very little heat in the form of IR that can cause damage to sensitive objects or fabrics. Wasted energy is dispersed as heat through the base of the LED.
LEDs mostly fail by dimming over time, rather than the abrupt failure of incandescent bulbs.
LEDs can have a relatively long useful life. One report estimates 35,000 to 50,000 hours of useful life, though time to complete failure may be longer. Fluorescent tubes typically are rated at about 10,000 to 15,000 hours, depending partly on the conditions of use, and incandescent light bulbs at 1,000–2,000 hours.
LEDs, being solid state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs which are fragile. Require zero maintenance and do not contain harmful or hazardous chemicals associated with other low energy lighting products. Turn on Instantly from -40C° to 185C°, making them ideal for applications subject to frequent on-off cycling, such as garages and basements.
The solid package of the LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner.
LED lighting solutions are available in most common formats and can replace almost all existing applications.
