Use LEDs Bulbs At Home—Some Features About LEDs Bulbs

I have often heard people say that they do not like CFL lights because the color is wrong, they're too yellowish or dingy. Well, they weren't kidding, the light can be a slightly different color - some folks are simply more sensitive to the color of light than others. By paying attention to the information on the bulb container, you may be able to adjust the color of the light your purchasing by noticing the warm and cool scale indicating the kelvin temperature of the light. What is light appearance?That brings us to Light Appearance. See along the bottom where it has a line and it says warm on the left and cool on the right? And underneath the line, over on the left side is a small arrow with the figure 3000 K. This small graph gives us an indication of the color of the light that is produced. This business of light being colored and referring to light color as warm and cool reminds me of referring to a drink as being dry, basically it makes little sense. What we might need to remember concerning light color is this: The K behind the number ( 3000 K ) refers to temperature on the Kelvin scale.Color temperatures over 5000 K are cool colors and are usually bluish white in color.Lower color temperatures ( 2,700 - 3000 K ) are called warm colors and are usually yellowish white through red.A warmer or lower color temperature is often used in public areas and promotes relaxation.A cooler or higher color temperature is often used to enhance concentration and focus as in an office setting. How long will a LEDs bulbs last?Right below the LED in the picture is the pronouncement - Long Lasting, 25,000 hours.How long is 25,000 hours? 24 hours in a day, do some dividing, and you get 1000 days, divide again, 2.74 years. So, right there on the package, it is telling us that this light bulb will brighten our lives, burning continuously for 2.74 years. Compare this to the 10,000 hours of a CFL and the 1,000 hours of an incandescent and the LED is the hours winner. Look at the lower left corner of the picture, see where it says, 7.5 W - 40 W and indicates that 1 LED bulb equals 25 incandescent bulbs? That means in energy use, measured in watts, a 7.5 watt LED equals the energy use of a 40 watt incandescent bulb. It is also indicating that the lifetime of one LED equals the lifetime of 25 incandescent bulbs. Most of your incandescent bulbs have a lifetime of 1000 hours compared to the 25,000 hours of the LED. How bright is a 7.5 watt LED bulb?Looking again at the picture, the package gives the information that this bulb gives off 450 lumen's. Of course, lumen's is how we measure the power of light perceived by the human eye. The more the lumen's, the more bright the light. Of course! 7.5 watt ( 40 watt ) LED produces 450 lumen's.13 watt ( 60 watt ) CFL produces about 900 lumen's.60 watt incandescent, soft white, 840 lumen's. Is the LEDs bulbs being used in the home office where you need more light, or in the ceiling fan with five other bulbs where you do not need the light bulb to be so bright. When selecting a light bulb, what you might want to consider is the number of lumen's in comparison to the watts - lumen's per watt - energy efficiency would be increased with lots of lumen's and little watts. The other thing to consider with lumen's is how much light does your application call for.
