Lighting Up Your House With LEDs - Are They Overrated? led tv 3dMore and more homeowners are turning their eyes in the direction of LED bulbs as a technique to save energy. But will you really get the best effectiveness by buying this still expensive alternative right away? Or is it better to wait, or to buy other energy-efficient lighting, and use the savings that generates to buy LED house lights later on?
You have most likely seen LEDs already: camping headlamps, LED Christmas tree lights, wind-up unexpected emergency flashlights. How about LED house lights? If LEDs use so little energy, why aren't manufacturers scrambling to sell LED lights for the home, and why aren't consumers scrambling to buy them?
I wouldn't try to sell you on LED lights as a way to address high energy bills or as the most environmentally beneficial lighting solution around. In fact, I think LEDs have a stretch to go yet, in terms of mild power, durability, and price. There are some LED applications you should invest in now, such as LED Christmas lights. And you might enjoy testing out one or two LED lights, if you're the energy-conserving type. But you are going to do better keeping with your current lighting, and moving over to fluorescent lighting in the short term. Compact fluorescent lights, or CFLs, will pay for themselves before LEDs have improved enough to make CFLs obsolete.
LEDs are more efficient than incandescent or fluorescent bulbs. But LEDs have very directed mild. An incandescent bulb shines over a wide area quite evenly, while LED bulbs are very focused, so that the area they directly illuminate is very bright, while the further you go from the direct beam, the fainter the mild. For LED Christmas lights, that isn't an issue you just want some bright factors of mild, which LEDs do very efficiently. But an incandescent or CFL will do a much better job of lighting your dining room than an LED bulb in the same fixture. The mild will be more evenly and broadly unfold, and with a warmer color temperature.
When you see LED merchant statements of LED mild output, you should be suspicious. A score in Lumens, which indicates brightness, is misleading for LEDs, because of their focused beam. Lumens levels are measured using a sensor positioned immediately below the mild supply. A household LED bulb at 2 watts could have the same lumens score as a 50 watt incandescent lamp, or as a 15 watt compact fluorescent, but the LED bulb may only deliver a focused mild directly below it to the photo sensor, while the incandescent bulb and compact fluorescent will mild up a much broader area, and still give that same lumens measurement for the area immediately beneath the bulb. This could be the supply of a frequent negative comment among LED purchasers, such as: "The packaging statements this 2-watt LED mild is equivalent to a 50-watt incandescent but it seems closer to a 30-watt incandescent bulb to me."
When it comes to halogen lights, they are only as energy efficient as incandescent bulbs, so the same energy effectiveness considerations apply here. But since halogen lights are generally much more focused than incandescent lights, LED house lights that are made to be swapped in to replace halogen lights are both more efficient than the halogens they replace, and work well for the direct lighting that halogen bulbs are known for. You can purchase LED replacements for the most common halogen bulbs such as GU10 and MR13, and here is where you may want to start the switchover.
LED house mild designers work around the problem of the slim beam of a mild emitting diode, by designing household LED bulbs that are a assortment of individual LEDs, with each LED aimed at a different angle, so that a wider area is highly illuminated. This increases the angle of full mild provided by an LED mild. However very few such bulbs provide the breadth of area coverage of traditional incandescent bulbs or CFLs and at the same time match their total mild output.
Where LED lights are an improvement over current bulbs is as replacements for lighting that is (or should be) highly directed. For example, a mild in a slim hall, where the chief point of the mild is to show people their way from one room to another, would be a good use of LEDs.
Task lighting is another area where LEDs are suitable. Why mild up your entire workshop if all you need to see is the tools on the work bench right before your eyes? A couple of LED bulbs hanging above the work bench will do the job. But you can only cost-justify this in energy savings if you live fifty percent your life in the workroom.
LED lights are, in theory at minimum, very reliable, when compared to incandescent bulbs and CFLs. LED bulb life ranges from 35,000 to 200,000 hrs, versus 1,000 hrs for an incandescent mild, and 8,000 hrs for a CFL. But I have seen consumer reviews of LED lights that report burn-out within a few weeks of installation. So there are quality control issues still to be settled - again, this is a good reason for holding off a year or two before a major conversion to LEDs.
Whether LEDs will really fulfill their long life expectancy stays to be seen - even the 35,000 hour types would need to be left on 24x7 for 4 years before they come near to reaching their marketed range. And LED lights do dim with age - so while a bulb might have a lifetime of 35,000 hrs, that doesn't mean it will emit its starting mild level for the full 35,000 hrs - the more mature it gets, the less mild it will emit. LED lights do slowly fade in brightness and therefore in effectiveness, although they will remain more efficient than both CFLs or incandescent bulbs throughout their life.
The "color temperature" of a mild, measured in 'degrees Kelvin', decides how we respond to its mild. Most people are used to the yellowish glow of incandescents at around 2800 Kelvin (2800K), even though fluorescent lights are closer to the natural daylight temperature of 6000K. Any LED house mild with a color temperature of 6000K or higher will seem to appear bluish, and any LED house mild with a color temperature over about 4000K will appear whiter than an incandescent.
While people are typically worried about how fluorescent or LED lights can make their rooms look hospital- white instead of the comforting yellow hue given off by incandescent lamps, remember that a little compromise on color temperature will really help reduce your energy bill. Be a trend-setter, not a trend-follower - start converting your lights to true daylight colors, whether with fluorescent lights or LED house lights. You will make it easier for your neighbors to change over, when they find out they won't be the first people with a slightly bluer mild tinge in their homes.
Whether you change some of your lights to LED lights now, or wait for the technology and reliability to improve, you can be sure that LEDs will play a bigger part in lighting our houses in the years forward. In my opinion it makes sense to wait, except in certain special lighting situations where the highly directed, focused mild of LEDs is what you want, and where you have money to spare. If you just want to save money - or to cut your energy use for environmental reasons - the same amount of money invested on weather-
