Instead, an alternate kind of measurement should be used: lumens.<br /><br /> For reference, here's a chart that reveals the watt-lumen conversion for incandescents and LEDs.<br /><br /><br />Deciding on the best color LED<br />You can always count on incandescents providing a warm, yellowish color. But LEDs come in an extensive variety of colors.<br /><br /><br />LED lightbulbs can handle showing an impressive colour variety, from purple to red, to a spectrum of whites and yellows as shown off by the Philips Hue. For the home, nevertheless, you're probably trying to find something similar to the light that incandescents generate.<br /><br />While lightbulbs labeled as bright white will produce a whiter light, closer to daylight and similar to what you see in retail stores, warm white and soft white will create a yellow color, close to incandescents.<br /><br /> The lower the number, the warmer (yellower) the light. So, your typical incandescent is somewhere between K. 2,700 and 3,500 If that's the colour you're going for, look for this particular range while shopping for LED bulbs.<br /><br />You'll pay more for an LED bulb<br />LED lightbulbs are like hybrid cars: not more expensive to operate but expensive upfront.<br /><br />Don't expect to save buckets of cash, when changing to LED lightbulbs. Instead, think of it as an investment. Luckily, competition has increased and LED bulbs have come down in cost, but you should still expect to pay much more than an incandescent.<br /><br />The LED lightbulbs will pay off, and in the meantime, you'll love even the choice of controlling them, longer bulb life, and less heat production.<br /><br />Bottom line: you will not see substantial savings in your electricity bill, unless you are 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 dimming switches that are traditional. In some instances, the switch must be replaced. Other times, you will pay a bit more for a compatible LED.<br /><br />Most dimmers, which were probably designed to operate with incandescents, work by cutting the number of electricity sent to the bulb off. The less electricity drawn, the dimmer the light. But with your newly acquired knowledge of LED lingo, you realize that there's energy drawn and no direct correlation between LED brightness.<br /><br />This guide describes why some LEDs will hum, flickr, or buzz when tied to your dimmer.<br /><br />When shopping for LEDs, it helps to know what kind of dimming switch you have, but should youn't understand (or would rather not go through the trouble), simply search for <img src="http://librestock.com/media/thumbs/metal-444497_640.jpg" align="right" width="283" style="padding:10px;"/>LED bulbs compatible with standard incandescent dimmers. We tested a slew of them to find out which LED bulbs work best with dimmers to make things simpler for you.<br /><br />LEDs should be used by not all light fixtures<br />Understanding where it is OK to place an LED will ensure the bulb won't fizzle ahead of its time.<br /><br /><br />You probably understand that LED lightbulbs run not drastically warmer than their incandescent cousins, but that doesn't mean they don't create heat. LED lightbulbs do get hot, but a heat sink pulls away the heat in the base of the lightbulb.<br /><br />And therein lies the issue: the lightbulb needs a way to dissipate the warmth.
