The brightness of LEDs, nevertheless, is ascertained a little differently.<br /><br /><br />Contrary to common belief, wattage is not a measurement of how much energy the bulb draws, although an indicator of luminosity. For incandescents, there's an approved correlation between the brightness and the watts drawn, but watts are not of how bright the bulb will be a great predictor. (The purpose, in the end, is they draw less energy.)<br /><br />For instance, an LED lightbulb with comparable brightness to a 60W incandescent is only 8 to 12 watts.<br /><br /><br /> Instead, a different form of measurement should be used.<br /><br />The lumen (lm) is the real measurement of brightness provided by a light bulb, and is the number you ought to look for when shopping for LEDs. For reference, here's a chart that shows the watt-lumen conversion for LEDs and incandescents.<br /><br /><br />Choosing the right colour LED<br />You always have the option to count on incandescents providing a warm, yellowish colour. But LEDs come in a wide variety of colors.<br /><br /><br />As shown off by the Philips Hue, LED lightbulbs are capable of displaying an impressive color range, from purple to red, into a spectrum of whites and yellows. For something similar to the light, yet, you are likely looking for the home that incandescents produce.<br /><br />Warm white and soft white will produce a yellow color, close to incandescents, while lightbulbs tagged as brilliant white will create a whiter light, closer to daylight and similar to what you see in retail stores.<br /><br /> So, your typical incandescent is someplace between 2,700 and 3,500K. Look for this particular variety while shopping for LED lightbulbs for, if that's the color you are <img src="http://images.freeimages.com/images/thumbs/e46/faces-1621072.jpg" align="left" width="239" style="padding:10px;"/>going.<br /><br />You will pay more for an LED lightbulb<br />LED bulbs are like hybrid cars: not more expensive to work but costly upfront.<br /><br />Don't expect to save buckets of cash when switching to LED lightbulbs. Think of it as an investment. Luckily, competition has grown and LED lightbulbs have come down in price, but you still ought to expect to pay more than an incandescent.<br /><br />The LED bulbs will pay off, and in the meantime, you will love even the choice of controlling them with your smartphone, longer bulb life, and less heat generation.<br /><br />Bottom line: you won't see significant savings in your electricity bill unless you're replacing many incandescent bulbs in a big house.<br /><br />Be cautious about non-dimmable LEDs<br />Due to their circuitry, LEDs are incompatible with conventional dimming switches. In some instances, the switch must be replaced. Other times, you will pay only a little more for a LED that is compatible.<br /><br />Most dimmers, which were probably designed to function with incandescents, work by cutting off the amount of electricity sent to the lightbulb. The electricity that was less drawn, the dimmer the light. But with your recently acquired knowledge of LED lingo, you realize that there is energy drawn and no direct correlation between LED brightness.<br /><br />This guide explains why some LEDs will hum, flickr, or buzz when tied to some dimmer.<br /><br />If you'd like your LED to be dimmable, you have to do 1 of 2 things: locate LED bulbs compatible with conventional dimmers, or replace your current dimming switch with a leading-edge (LED-compatible) dimmer.<br /><br />
