Meet the Next Generation LED Light Bulbs

26 Jul

Incandescent bulbs which convert 90% of the power that they consume into heat are energy swallowing monsters since they emit light by transforming power into heat first. When the tungsten filament achieves a certain temperature, it will emit light. However, only 10% of the power is effectively transformed into light, other 90% is wasted. Next generation LED light bulbs with light emitting diodes as light source which are cold light source have the classic incandescent appearance with traditional standard bases. LED light bulbs are much more energy efficient, more durable and more eco-friendly with over 50,000 hour lifespan than incandescent bulbs.

LED light bulbs can deliver the same brightness as incandescent bulbs do with only 10% energy consumption as incandescent bulbs’. LEDs are brand new light source with a luminous flux of over 100 lumen per watt for indoor lighting. LED light bulbs can easily deliver high lumen output with low power consumption. 90% energy savings can greatly reduce your electricity bills. Meanwhile LED light bulbs bring more comfortable light which is more suitable for residential lighting and will not cause eye strain. Whereas incandescent bulbs bring sharp light which can do harm to human beings’ eyes.

LED light bulbs are solid state lighting fixtures which are more durable than incandescent bulbs. Incandescent bulbs are fragile while LED light bulbs are shock proof. LED light bulbs can last over 50,000 hours while incandescent bulbs can only last 1,000 hours, which means that you can save bulb replacement costs during the lifetime of LED light bulbs. Just install the LED light bulbs and leave them alone, you even don’t have to maintain them.

LED light bulbs are more eco-friendly than incandescent bulbs since they are made from 100% recyclable materials. LED light bulbs do not contain any hazardous materials such as mercury and lead which can do harm to human beings’ health. And also when you dispose LED light bulbs, they will not cause any environment pollutions.

To sum it up, next generation LED light bulbs are the optimum replacement for incandescent bulbs. They can be easily installed into most traditional fixtures, plug and play, and you will benefit much from them.

Choose Your Way from CFL to LED Light Bulbs

26 Jul

Compact fluorescent lamps nowadays are widely used for residential lighting and commercial lighting, and they are energy saving lamps when compared with incandescent lamps and halogen lamps. LED light bulbs are the new generation of light source which is designed to replace conventional lamps including CFL. Then what are the advantages of LED light bulbs over compact fluorescent lamps? Why should CFL be replaced by LED light bulbs?

Firstly LED light bulbs are more energy efficient than compact fluorescent lamps. LED light bulbs can deliver the same light intensity as compact fluorescent lamps with only 50% energy consumption due to the high efficacy of LEDs. Meanwhile the light quality of LED light bulbs can be equivalent to compact fluorescent lamps’ when combining specially designed optic lens.

Secondly LED light bulbs’ lifetime can be as 10 times as compact fluorescent lamps’. LED light bulbs can last over 50,000 hours while compact fluorescent lamps can only last around 5,000 hours. LED light bulbs are more durable than compact fluorescent lamps since they are solid lighting fixtures. During the lifetime of LED light bulbs, you can save expensive bulb replacement costs and maintenance costs. In addition, LED light bulbs emit little heat to the environment, which will greatly reduce the corresponding electricity bills for air conditioners.

Thirdly LED light bulbs do not contain any hazardous materials which may pollute the environment after disposal. Compact fluorescent lamps contain mercury which is harmful to human body and the environment.

Although LED light bulbs are more expensive than compact fluorescent lamps, they are more cost effective than compact fluorescent lamps during their lifetime.

Advantages and Disadvantages of LED Tube Lights

16 Jul

LED tube lights are designed with the latest LED lighting technology and high efficient LEDs, and they are supposed to replace conventional CFLs which are widely used for commercial lighting and residential lighting. Why LED tube lights can replace conventional CFLs? What are the advantages of LED tube lights? LED tube lights feature many advantages when compared to CFLs.

LED tube lights are of high energy efficiency. LED tube lights adopt high efficient LEDs as light source, which can achieve a luminous efficacy of 100 lumens per watt. Therefore LED tube lights can deliver the same light output as CFLs do while just consume 50% energy as CFLs do, which means by using LED tube lights to replace CFLs you will save over 50% energy bills.

LED tube lights can last over 50,000 hours, which is as ten times as the lifetime of CFLs. LED tube lights are solid state lighting fixtures, so they can last much longer than conventional lighting fixtures. During their lifetime, LED tube lights hardly need any maintenance, which will greatly save your maintenance costs. Meanwhile, you don’t have to replace bulbs frequently since they can last more than 10 years, and the bulb replacement costs they save for you can be also very considerable.

LED tube lights are green and eco-friendly lighting fixtures without any hazardous materials such as mercury and lead. They will not cause any environment pollutions when they are disposed. Unlike CFLs, LED tube lights do not emit IR or UV radiation, and they do no harm to human beings’ health.

As a matter of fact, LED tube lights are far more than the above mentioned advantages. However, LED tube lights also feature some disadvantages. LEDs are currently more expensive, price per lumen, on a startup cost basis, than more conventional lighting technologies. The additional expense partially stems from the relatively low lumen output and the drive circuitry and power supplies needed.

LED performance largely depends on the ambient temperature of the operating environment. Over-driving the LED in high ambient temperatures may result in overheating of the LED package, eventually leading to device failure.

LEDs do not approximate a “point source” of light, so cannot be used in applications needing a highly collimated beam.

Save Energy with LED Tube Lights

16 Jul

Conventional fluorescent tubes are widely used not only for commercial lighting, but also for residential lighting nowadays, although they are of great advantage to incandescent bulbs and halogen bulbs and are more energy efficient, they are still not energy efficient and eco-friendly enough compared with LED tube lights.

Thanks to the high efficacy of LEDs, LED tube lights can save over 50% energy over conventional fluorescent tubes. Come with frosted lens, LED tube lights can deliver beautiful and high quality light that you would expect from CFLs, while just consume a half of energy that CFLs consume. Meanwhile, LED tube lights contains no hazardous materials such as mercury and lead, and working under LED tube lights for a long period will not cause headache and eyestrain.

Assume that you family has ten 60 watt conventional fluorescent tubes, and every day you use them for 5 hours, and the price for electricity is 0.17 US dollars per Kwh, and the energy bills per year will be 186.15 US dollars. If you switch all the conventional fluorescent tubes to LED tube lights, you will only need four 25 watt LED tube lights, and the energy bills per year will be 75.65 US dollars. You can save 110.5 US dollar energy bills every year, which does not include the maintenance cost saving and air conditioner expense saving due to the long lifetime and low heat generation of LED tube lights. The total saving can be much more than just 110.5 US dollars.

LED tube lights can be the ideal replacement for conventional fluorescent tubes since they are more energy efficient and eco-friendly. Just switch the energy wasting old tubes to the brand new LED tubes, save your energy bills and bulb replacement costs, and create green and healthy lighting for your family.

LED Household Illumination – How You Can Have The Benefit Of It

15 Jul

Lot of individuals have come across LED home lighting in one form or another; usually in torches, Christmas light fittings and solar or mains powered garden lighting. However many are still ignorant that home LED home lighting is currently not only possible, but very much the future of household lighting.

The Lighting Business is rapidly dropping additional investment within the present generation of low-power lamps (Compact Fluorescent Lamps or CFLs – ungainly, garish and, being crammed with Mercury vapour, a disposal nightmare). Firms like Philips Lighting Corporation have already stated their dedication to LED home lighting as the best way forward.

Consequently the provision, range and affordability of LED home lighting solutions is rising at an explosive rate. However as at this point it is still best to set up LED home lighting into your personal home by approaching those application that LEDs are best in a position to replace.

The important distinction between conventional incandescent light bulbs and LED lights is that the former wastes as much as ninety eight% of the electrical energy provided as heat however does shine light in all directions, whereas LED light sources convert almost all their electrical energy into light (therefore the reason they stay cool to the touch) however shine a pure and very intense directional light.

Another key differentiator is value of ownership. LED light bulbs last an extremely long time (three decades of normal use) and cost so little to run that the amount of electricity utilised throughout the entire life time of a bulb is almost certain to be less than the price of the bulb itself. It is in stark contrast to normal non-LED bulbs which are typically well over 500 times the purchase price of the bulb itself in operating and replacement costs.

These certain qualities (extremely efficient, zero fire risk and focused light) make LED light bulbs a perfect alternative for spot lights, particularly the popular halogen lamps currently found in numerous homes and that waste heat and money in abundance.

However changing domestic halogen down lighters is just one aspect of spot lighting that LED lamps are good for. In addition they make appropriate display lights and as a bonus can be put in places where you couldn’t even think about using conventional incandescent spot lights due to the danger of damage and fire from their extremely high operating temperature.

LED spot illuminations are a natural alternative for bringing illumination to display units, cabinets, beneath kitchen shelves and inside cupboards and wardrobes. They can be readily installed next to objects and surfaces without any threat of causing heat damage and often give a much better light than ordinary light bulbs in such uses.

The other dimension that home LED home lighting is revolutionizing is mood lighting, bringing completely new array of effects that existing lighting technology can not begin to emulate. LED mood lighting offers a brand new palette of vibrant color that may be altered and blended at will to produce stunning effects, either as a focal point or cast against floor surfaces, ceilings and walls to change the ambiance of any room or space in your house.
