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.

 

The History of Light Bulbs From Incandescent to Fluorescent Bulb and LED

11 Jul

Out of all of the inventions that mankind has brought about, there is one that has made so many of the other inventions possible. The light bulb has so drastically changed the course of human events, that it only seems fitting to learn a little more about this incredible invention.

Everyone knows that the light bulb was invented in 1879 by Thomas Edison, right? Wrong! Artificial electric light first happened in 1810 when Englishman Humphrey Davy invented a lamp connecting a battery to coal using two wires that caused the coal to become electrically charged and glow. Then came Edison right? Nope! It was Joseph Swan in 1860 who patented the first incandescent lamp with a filament, or the first light bulb. In 1878, Swan replaced the filament, originally made of paper, with one made of cotton thread and demonstrated it to the world, a full year before Edison. Edison bought the patent and began to work on improving the life span of the light bulb, eventually getting it to last from 1200-1500 hours instead of only 13 1/2 hours.

After his work with the incandescent bulb, Edison moved on to fluorescent lighting, seeing the potential for it’s use commercially. In 1896, he invented a fluorescent lamp that used a coating of calcium tungstate as the fluorescing substance and had it patented in 1907. Fluorescent lighting really took off during World War II and by 1951 in the US, more lighting was produced by fluorescent lights than incandescent bulbs.

In the 1960s, General Electric, Texas Instruments and RCA Laboratories began developing the LED, or Light Emitting Diode, lights. Light emitting materials had been around since the early 1900s but hadn’t been properly researched. Through their research, it was discovered that when electric currents were applied to crystals of gallium arsenide, the crystals gave off infrared radiation. The first visible light emitted from LED’s was red, which have been used in indicator devices since the 1970s, followed by blue in 1971 and green, amber, yellow, and white in the early 1990s. It was during this time when energy efficient light bulbs facts were also discovered.

Incandescent, fluorescent and energy efficient light bulbs LED are everywhere these days, from giant billboards to restaurant signs to the lamps in our own homes. Imagine all the hours of work that were put into these inventions by so many dedicated inventors. Truly no invention of the 20th century has so drastically changed the lives of people worldwide as the light bulb. If only Thomas Edison could read LED light bulb reviews today, he would see the light!

 

Led Lights: The Next Generation Of Home And Outdoor Lighting

07 Mar

Light Emitting Diode or LED lighting has been in existence for many years, mainly in niche applications like small trinkets and indicator lighting. However, due to LED lighting being highly energy efficient, not to mention technologically superior over other light sources such as incandescent and fluorescent lighting, it is forecasted to reach beyond electronic applications into commercial and home LED lighting as well. In a recent report by Global Industry Analysts it is predicted that the market for fluorescent and LED lighting could climb to $97 billion by 2010. The spike in growth would be mainly from construction and industrial development industries.

As more individuals become aware of the energy efficiency of LED lighting, the price of such items as LED bulbs will decrease in price. Currently, the price of one LED bulb is substantially higher than the price of incandescent or fluorescent lighting. However, the initial price for LED bulbs would more than pay for itself in the long run. On average, one incandescent 60-watt bulb lasts 1,000 hours whereas one 2-watt LED light bulb lasts 60,000 hours. Therefore, one would need to purchase 60 incandescent bulbs for every one LED light bulb.

Home LED lighting is a cut above the rest when it comes to energy efficiency. As compared to incandescent lighting, LED lighting wins hands down where energy consumption is concerned. For every 60,000 hours of usage, incandescent lighting uses approximately 3,600 kWh of electricity where LED lighting uses 120 kWh. Bottom line: energy efficiency equals a significant cost savings. LED lighting gives off directional light. Therefore, it is useful as a source of light for reading or spotlighting in the home. Its powerful light output also makes it great for outdoor floodlighting and path illumination. LED bulbs are now available that can replace most halogen or fluorescent light bulbs used in the home.

Although LED lighting may not be useful for all home lighting needs, replacing a few bulbs with LED bulbs would have a noticeable affect in the amount of electricity used.

LED light displays are already used in signs and videos in many indoor and outdoor sporting events and concerts. LED video displays and signs are often preferred because of their higher brightness, which is critical when people are viewing a sign or video from a long distance. Added advantages of LED video displays are their capacity to incorporate curves and 3-D design. This makes LED video displays technologically superior to currently available large screen displays. Research and developers in the consumer electronics space are eager to take advantage of this overwhelmingly useful technology in future products.

Other uses for LED lighting include LED flashlights and key chains, automobile taillights and interior lights, and LED based projection televisions. LED lighting is also being used in the military for LED flashlights that work with night-vision goggles, UV-LED canteen water treatment devices and the sterilization of surgical equipment.

With LED lighting being more energy efficient and technologically superior to many other light sources, numerous LED light applications are sure to evolve. Future generations can expect to consider LED lighting as the standard light source for most lighting applications.

 

USB Aquarium Refit with Circulation Pump, LED Lights & Thermometer

03 Mar

As self describe tech geeks we do have to admit that we love USB gadgets. Whether it’s a Delorean clad hard drive, a set of cufflinks that hide flash drives, or even Lady Gaga LCD shades. You can take the corniest, oddest, kitschiest thing in the world and stick a USB plug on it and we probably will think its cool; however, when a company not only takes an existing device but MULTIPLE devices and makes it USB interface-able… .that goes beyond cool and cranks the cool dial all the way to 11!

Take the USB Aquarium with Alarm Clock and Thermometer. This funky little thang is first and foremost an honest to god fish tank that has its recirculation pump work off the 5volt line of your USB port. This by itself is pretty cool as we always thought those fake fish USB tanks were really lame. This right here would make the USB Aquarium with Alarm Clock and Thermometer pretty cool, but Brando was not satisfied with just making a real fish tank that connects to your computer but it is also a working alarm clock (with built in LCD display), has a built in thermometer and even sports a 6 LED light! This shotgun approach to novelty kitsch means even if the idea of water + computer scares you then maybe a Zen garden fish tank with alarm clock or one of the myriad of other possibilities will tickle your fancy. All in all, the USB Aquarium with Alarm Clock and Thermometer is pure kitsch, but it has elevated it a freakin’ art form and for that we really think its awesomely, geek cool that will at the very least make for a great show piece in your cubicle… .as long as you don’t mind shelling out $40 for kitsch that is!
