Recessed downlights are commonly used in residential kitchens, hallways, and bathrooms, and in a number of office and commercial settings. DOE estimates there are more than 600 million recessed downlights installed in U.S. homes and businesses.


LEDs consume far less electricity than incandescent bulbs, and decorative LED light strings such as Christmas tree lights are no different. Not only do LED holiday lights consume less electricity, they also have the following advantages:


In the early 60s, a young scientist working for General Electric developed the first LEDs. Companies first used them as indicator lights for circuit boards, and they became known for their durability and energy savings. Many municipalities used the second generation of LEDs, which became available in the 80s and 90s, as replacements for the traditional incandescent bulb in streetlights. Some people began to experiment with using them as a replacement for fluorescent lights in outdoor signs.


If you replaced all the lighting in your office, school or other facility with LEDs, you could see as much as a 60% to 70% improvement in your overall energy savings. In some cases, the improvement could be as great as 90%, depending on what kind of lights you are replacing and what kind of LED lights you are using.


These improvements in energy efficiency are directly correlated with financial savings. When you replace a traditional light source with an LED light source, your energy usage is going to plummet, making LED lights are a smart investment for the bottom line of any business!


The environmental benefits of LED lighting also extend to their manufacturing process. Many traditional lighting sources, like fluorescent lighting and mercury vapor lights, use mercury internally as part of their construction. Because of this, when they reach the end of their lifespans, they require special handling. You do not have to worry about any of these issues with LED lights.


LED lights, on the other hand, perform better in cold temperatures by about 5%. This is why LED lights are a better choice for lighting needed in freezers, meat lockers, cold storage spaces or refrigerated display cases. Their ability to perform so efficiently in cold weather also makes them the perfect choice for lights in parking lots, lights used to illuminate the perimeters of buildings and lights used in outdoor signage.


Also, traditional lighting sources have a shorter lifespan if you frequently switch them on and off. LED lights are not affected by frequent switching. It does not cause any reduction in their lifespan or efficiency.


This feature makes LEDs an ideal solution for your business if you need your lights to come back on immediately after a blackout or a power surge. This capability is also useful if you want your lights to come on promptly when an employee opens a building early in the morning before the sun comes up.


LED lights do cost more than traditional lighting sources but these costs fall with each passing year. Even if you have to pay a bit more upfront, what you save in the long term more than makes up for the higher upfront cost. LED lights are one of the most important developments in reducing energy usage and costs in the past few decades.


The first one was in the fifth inning, when Will Smith poked an RBI single to right field before the lights dimmed and flickered while Jake McCarthy fielded the ball and threw it back into the infield.


The second problematic light display came during the eighth inning as Diamondbacks reliever Carlos Vargas warmed up on the mound before his major league debut. Arizona catcher Gabriel Moreno had trouble seeing the pitches so home plate umpire Marvin Hudson immediately signaled to have someone turn the lights on.


LED lights can be your best choice for lighting your studio. They're inexpensive, don't put out the amount of heat that other studio lights do, and come in a variety of configurations. Their illumination is similar to natural light, and has the versatile color balance. When tungsten lights or fluorescent lights don't fit the situation or the budget, consider LEDs.


Light-emitting diodes are semiconductors that convert electricity to light. Although you might think of this type of light as new technology, an engineer at General Electric invented the first one in 1962. The original lights were red, followed by yellow, green, and blue. White lights debuted in the 1990s. While colored lights had been used only in things such as clocks and traffic lights, white LEDs gained widespread use in photography and video.


Why Use LEDs for Photos?LEDs can provide continuous light, as opposed to the off-and-on flashes of strobe lighting. For photography and videography, choose continuous light when you need to mimic certain types of illumination sources, or you need to see the result of composition before shooting an image. LEDs convert 90 percent of their energy into light. This makes them not only a cost-effective choice, but environmentally friendly as well. Like the tungsten light kits that are still popular in videography, LEDs come grouped with accessories in LED lighting kits. If you need convenience, some kits are built around battery LED lights.


LEDs offer a choice of styles. You can use a small panel on a light stand to highlight a face in a portrait, while larger LED panel lights would provide soft light for a full body image. Single LED lights are too small to light a photo, but used as accents, they could add interest to a picture.


Energy-efficient LEDs are cooler than traditional studio lights. You can place them close to a subject without causing discomfort. You can also use them in spaces that are too small to be safe for lights that run hot. These characteristics make LEDs useful for portrait photography. For drama in your portrait, put a light on either side of your subject. This results in an all-over highlight. If your design calls for only one highlight, place a light on just one side. Use colored LEDs to alter the mood in your photograph. Since LEDs are continuous light, you can move around as you compose a shot, or use a remote camera control. If you're a videographer, this constant light is suitable for action shots.


Enjoy season-long mosquito repellency without the hassle of expensive yard treatments of the mess and odor of sprays and creams. Our one-of-a-kind string lights offer a silent and invisible zone of 330 square feet of protection. Welcome your family and friends while driving away mosquitoes with these string lights with a 2-in-1 solution that pays off season after season.


Whether you hang them from a deck, trellis or between trees, each string light offers a variety of configurations. Add another string for even more design options. For best results, hang lights no higher than 10 feet above the ground.


But energy efficiency is just part of the story. The other part is time efficiency: A good-quality LED bulb theoretically can have a life span of 25,000 hours or more, while incandescent bulbs have a 1,000-hour life span. Solid-state lights like LEDs are more stable light sources than incandescent or fluorescent bulbs, and the difference is startling: You'd have to leave a LED light on for 24 hours a day, seven days a week for three years before it matches an incandescent bulb's life span. (In fairness, not all LED light bulbs last as long as they can in theory. Some may have shorter life spans if parts wear out prematurely.)


The reality is, even at $9.48 for a pack of four bulbs, LEDs will end up saving money in the long run, because you only need one every decade or two and you spend less money on home lighting, which can be six to seven times more energy efficient than incandescent lights and cut energy use by more than 80 percent.


LEDs are poised to take over household lighting. Philips has a collection of LED lights that includes color changes and Wi-Fi connected bulbs. And General Electric has a LED+ series that includes light bulbs with speakers, timers, color changes and more. It's estimated that LEDs will account for 75 percent of all lighting sales by 2030.


A growing number of studies have come out about the blue light that LEDs emit. Researchers say it may be damaging our eyes and health. A French health agency said it can damage the eye's retina while disturbing our biological rhythm and sleep disruption. The agency recommended limiting the use of LED devices with the highest blue-light content, especially for children. This would include computers, smartphones and other screens, as well as perhaps, certain toys and decorative lights.


Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light.[7] Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (UV), and infrared wavelengths, with high, low, or intermediate light output, for instance white LEDs suitable for room and outdoor area lighting. LEDs have also given rise to new types of displays and sensors, while their high switching rates are useful in advanced communications technology with applications as diverse as aviation lighting, fairy lights, automotive headlamps, advertising, general lighting, traffic signals, camera flashes, lighted wallpaper, horticultural grow lights, and medical devices.[8]


Surface-mounted LEDs are frequently produced in chip on board (COB) arrays, allowing better heat dissipation than with a single LED of comparable luminous output.[127] The LEDs can be arranged around a cylinder, and are called "corn cob lights" because of the rows of yellow LEDs.[128] 041b061a72
